-fstack-protector Enable stack protectors for some functions vulnerable to stack smashing. This uses a loose heuristic which considers functions vulnerable if they contain a char (or 8bit integer) array or constant sized calls to alloca , which are of greater size than ssp-buffer-size (default: 8 bytes). All variable sized calls to alloca are considered vulnerable. A function with a stack protector has a guard value added to the stack frame that is checked on function exit. The guard value must be positioned in the stack frame such that a buffer overflow from a vulnerable variable will overwrite the guard value before overwriting the function's return address. The reference stack guard value is stored in a global variable.

result is written to the standard output.
USAGE: clang-format [options] [@<file>] [<file> ...]
OPTIONS:
Clang-format options:
--Werror - If set, changes formatting warnings to errors
--Wno-error=<value> - If set, don't error out on the specified warning type.
=unknown - If set, unknown format options are only warned about.
This can be used to enable formatting, even if the
configuration contains unknown (newer) options.
Use with caution, as this might lead to dramatically
differing format depending on an option being
supported or not.
--assume-filename=<string> - Set filename used to determine the language and to find
.clang-format file.
Only used when reading from stdin.
If this is not passed, the .clang-format file is searched
relative to the current working directory when reading stdin.
Unrecognized filenames are treated as C++.
supported:
CSharp: .cs
Java: .java
JavaScript: .js .mjs .cjs .ts
Json: .json .ipynb
Objective-C: .m .mm
Proto: .proto .protodevel
TableGen: .td
TextProto: .txtpb .textpb .pb.txt .textproto .asciipb
Verilog: .sv .svh .v .vh
--cursor=<uint> - The position of the cursor when invoking
clang-format from an editor integration
--dry-run - If set, do not actually make the formatting changes
--dump-config - Dump configuration options to stdout and exit.
Can be used with -style option.
--fail-on-incomplete-format - If set, fail with exit code 1 on incomplete format.
--fallback-style=<string> - The name of the predefined style used as a
fallback in case clang-format is invoked with
-style=file, but can not find the .clang-format
file to use. Defaults to 'LLVM'.
Use -fallback-style=none to skip formatting.
--ferror-limit=<uint> - Set the maximum number of clang-format errors to emit
before stopping (0 = no limit).
Used only with --dry-run or -n
--files=<filename> - A file containing a list of files to process, one per line.
-i - Inplace edit <file>s, if specified.
--length=<uint> - Format a range of this length (in bytes).
Multiple ranges can be formatted by specifying
several -offset and -length pairs.
When only a single -offset is specified without
-length, clang-format will format up to the end
of the file.
Can only be used with one input file.
--lines=<string> - <start line>:<end line> - format a range of
lines (both 1-based).
Multiple ranges can be formatted by specifying
several -lines arguments.
Can't be used with -offset and -length.
Can only be used with one input file.
-n - Alias for --dry-run
--offset=<uint> - Format a range starting at this byte offset.
Multiple ranges can be formatted by specifying
several -offset and -length pairs.
Can only be used with one input file.
--output-replacements-xml - Output replacements as XML.
--qualifier-alignment=<string> - If set, overrides the qualifier alignment style
determined by the QualifierAlignment style flag
--sort-includes - If set, overrides the include sorting behavior
determined by the SortIncludes style flag
--style=<string> - Set coding style. <string> can be:
1. A preset: LLVM, GNU, Google, Chromium, Microsoft,
Mozilla, WebKit.
2. 'file' to load style configuration from a
.clang-format file in one of the parent directories
of the source file (for stdin, see --assume-filename).
If no .clang-format file is found, falls back to
--fallback-style.
--style=file is the default.
3. 'file:<format_file_path>' to explicitly specify
the configuration file.
4. "{key: value, ...}" to set specific parameters, e.g.:
--style="{BasedOnStyle: llvm, IndentWidth: 8}"
--verbose - If set, shows the list of processed files

root@kali:~# clang-format-diff -h
usage: clang-format-diff [-h] [-i] [-p NUM] [-regex PATTERN] [-iregex PATTERN]
[-sort-includes] [-v] [-style STYLE]
[-fallback-style FALLBACK_STYLE] [-binary BINARY]
This script reads input from a unified diff and reformats all the changed
lines. This is useful to reformat all the lines touched by a specific patch.
Example usage for git/svn users:
git diff -U0 --no-color --relative HEAD^ | clang-format-diff -p1 -i
svn diff --diff-cmd=diff -x-U0 | clang-format-diff -i
It should be noted that the filename contained in the diff is used unmodified
to determine the source file to update. Users calling this script directly
should be careful to ensure that the path in the diff is correct relative to the
current working directory.
options:
-h, --help show this help message and exit
-i apply edits to files instead of displaying a diff
-p NUM strip the smallest prefix containing P slashes
-regex PATTERN custom pattern selecting file paths to reformat (case
sensitive, overrides -iregex)
-iregex PATTERN custom pattern selecting file paths to reformat (case
insensitive, overridden by -regex)
-sort-includes let clang-format sort include blocks
-v, --verbose be more verbose, ineffective without -i
-style STYLE formatting style to apply (LLVM, GNU, Google,
Chromium, Microsoft, Mozilla, WebKit)
-fallback-style FALLBACK_STYLE
The name of the predefined style used as afallback in
case clang-format is invoked with-style=file, but can
not find the .clang-formatfile to use.
-binary BINARY location of binary to use for clang-format
root@kali:~# git-clang-format -h
usage: git clang-format [OPTIONS] [<commit>] [<commit>|--staged] [--] [<file>...]
If zero or one commits are given, run clang-format on all lines that differ
between the working directory and <commit>, which defaults to HEAD. Changes are
only applied to the working directory, or in the stage/index.
Examples:
To format staged changes, i.e everything that's been `git add`ed:
git clang-format
To also format everything touched in the most recent commit:
git clang-format HEAD~1
If you're on a branch off main, to format everything touched on your branch:
git clang-format main
If two commits are given (requires --diff), run clang-format on all lines in the
second <commit> that differ from the first <commit>.
The following git-config settings set the default of the corresponding option:
clangFormat.binary
clangFormat.commit
clangFormat.extensions
clangFormat.style
positional arguments:
<commit> revision from which to compute the diff
<file>... if specified, only consider differences in these files
options:
-h, --help show this help message and exit
--binary BINARY path to clang-format
--commit COMMIT default commit to use if none is specified
--diff print a diff instead of applying the changes
--diffstat print a diffstat instead of applying the changes
--extensions EXTENSIONS
comma-separated list of file extensions to format,
excluding the period and case-insensitive
-f, --force allow changes to unstaged files
-p, --patch select hunks interactively
-q, --quiet print less information
--staged, --cached format lines in the stage instead of the working dir
--style STYLE passed to clang-format
-v, --verbose print extra information
--diff_from_common_commit
diff from the last common commit for commits in
separate branches rather than the exact point of the
commits
root@kali:~# clang-tidy -h
USAGE: clang-tidy [options] <source0> [... <sourceN>]
OPTIONS:
Generic Options:
--help - Display available options (--help-hidden for more)
--help-list - Display list of available options (--help-list-hidden for more)
--version - Display the version of this program
clang-tidy options:
--allow-no-checks - Allow empty enabled checks. This suppresses
the "no checks enabled" error when disabling
all of the checks.
--checks=<string> - Comma-separated list of globs with optional '-'
prefix. Globs are processed in order of
appearance in the list. Globs without '-'
prefix add checks with matching names to the
set, globs with the '-' prefix remove checks
with matching names from the set of enabled
checks. This option's value is appended to the
value of the 'Checks' option in .clang-tidy
file, if any.
--config=<string> - Specifies a configuration in YAML/JSON format:
-config="{Checks: '*',
CheckOptions: {x: y}}"
When the value is empty, clang-tidy will
attempt to find a file named .clang-tidy for
each source file in its parent directories.
--config-file=<string> - Specify the path of .clang-tidy or custom config file:
e.g. --config-file=/some/path/myTidyConfigFile
This option internally works exactly the same way as
--config option after reading specified config file.
Use either --config-file or --config, not both.
--dump-config - Dumps configuration in the YAML format to
stdout. This option can be used along with a
file name (and '--' if the file is outside of a
project with configured compilation database).
The configuration used for this file will be
printed.
Use along with -checks=* to include
configuration of all checks.
--enable-check-profile - Enable per-check timing profiles, and print a
report to stderr.
--enable-module-headers-parsing - Enables preprocessor-level module header parsing
for C++20 and above, empowering specific checks
to detect macro definitions within modules. This
feature may cause performance and parsing issues
and is therefore considered experimental.
--exclude-header-filter=<string> - Regular expression matching the names of the
headers to exclude diagnostics from. Diagnostics
from the main file of each translation unit are
always displayed.
Must be used together with --header-filter.
Can be used together with -line-filter.
This option overrides the 'ExcludeHeaderFilterRegex'
option in .clang-tidy file, if any.
--explain-config - For each enabled check explains, where it is
enabled, i.e. in clang-tidy binary, command
line or a specific configuration file.
--export-fixes=<filename> - YAML file to store suggested fixes in. The
stored fixes can be applied to the input source
code with clang-apply-replacements.
--extra-arg=<string> - Additional argument to append to the compiler command line
--extra-arg-before=<string> - Additional argument to prepend to the compiler command line
--fix - Apply suggested fixes. Without -fix-errors
clang-tidy will bail out if any compilation
errors were found.
--fix-errors - Apply suggested fixes even if compilation
errors were found. If compiler errors have
attached fix-its, clang-tidy will apply them as
well.
--fix-notes - If a warning has no fix, but a single fix can
be found through an associated diagnostic note,
apply the fix.
Specifying this flag will implicitly enable the
'--fix' flag.
--format-style=<string> - Style for formatting code around applied fixes:
- 'none' (default) turns off formatting
- 'file' (literally 'file', not a placeholder)
uses .clang-format file in the closest parent
directory
- '{ <json> }' specifies options inline, e.g.
-format-style='{BasedOnStyle: llvm, IndentWidth: 8}'
- 'llvm', 'google', 'webkit', 'mozilla'
See clang-format documentation for the up-to-date
information about formatting styles and options.
This option overrides the 'FormatStyle` option in
.clang-tidy file, if any.
--header-filter=<string> - Regular expression matching the names of the
headers to output diagnostics from. Diagnostics
from the main file of each translation unit are
always displayed.
Can be used together with -line-filter.
This option overrides the 'HeaderFilterRegex'
option in .clang-tidy file, if any.
--line-filter=<string> - List of files with line ranges to filter the
warnings. Can be used together with
-header-filter. The format of the list is a
JSON array of objects:
[
{"name":"file1.cpp","lines":[[1,3],[5,7]]},
{"name":"file2.h"}
]
--list-checks - List all enabled checks and exit. Use with
-checks=* to list all available checks.
--load=<pluginfilename> - Load the specified plugin
-p <string> - Build path
--quiet - Run clang-tidy in quiet mode. This suppresses
printing statistics about ignored warnings and
warnings treated as errors if the respective
options are specified.
--store-check-profile=<prefix> - By default reports are printed in tabulated
format to stderr. When this option is passed,
these per-TU profiles are instead stored as JSON.
--system-headers - Display the errors from system headers.
This option overrides the 'SystemHeaders' option
in .clang-tidy file, if any.
--use-color - Use colors in diagnostics. If not set, colors
will be used if the terminal connected to
standard output supports colors.
This option overrides the 'UseColor' option in
.clang-tidy file, if any.
--verify-config - Check the config files to ensure each check and
option is recognized without running any checks.
--vfsoverlay=<filename> - Overlay the virtual filesystem described by file
over the real file system.
--warnings-as-errors=<string> - Upgrades warnings to errors. Same format as
'-checks'.
This option's value is appended to the value of
the 'WarningsAsErrors' option in .clang-tidy
file, if any.
-p <build-path> is used to read a compile command database.
For example, it can be a CMake build directory in which a file named
compile_commands.json exists (use -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
CMake option to get this output). When no build path is specified,
a search for compile_commands.json will be attempted through all
parent paths of the first input file . See:
https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html for an
example of setting up Clang Tooling on a source tree.
<source0> ... specify the paths of source files. These paths are
looked up in the compile command database. If the path of a file is
absolute, it needs to point into CMake's source tree. If the path is
relative, the current working directory needs to be in the CMake
source tree and the file must be in a subdirectory of the current
working directory. "./" prefixes in the relative files will be
automatically removed, but the rest of a relative path must be a
suffix of a path in the compile command database.
Parameters files:
A large number of options or source files can be passed as parameter files
by use '@parameter-file' in the command line.
Configuration files:
clang-tidy attempts to read configuration for each source file from a
.clang-tidy file located in the closest parent directory of the source
file. The .clang-tidy file is specified in YAML format. If any configuration
options have a corresponding command-line option, command-line option takes
precedence.
The following configuration options may be used in a .clang-tidy file:
CheckOptions - List of key-value pairs defining check-specific
options. Example:
CheckOptions:
some-check.SomeOption: 'some value'
Checks - Same as '--checks'. Additionally, the list of
globs can be specified as a list instead of a
string.
ExcludeHeaderFilterRegex - Same as '--exclude-header-filter'.
ExtraArgs - Same as '--extra-arg'.
ExtraArgsBefore - Same as '--extra-arg-before'.
FormatStyle - Same as '--format-style'.
HeaderFileExtensions - File extensions to consider to determine if a
given diagnostic is located in a header file.
HeaderFilterRegex - Same as '--header-filter'.
ImplementationFileExtensions - File extensions to consider to determine if a
given diagnostic is located in an
implementation file.
InheritParentConfig - If this option is true in a config file, the
configuration file in the parent directory
(if any exists) will be taken and the current
config file will be applied on top of the
parent one.
SystemHeaders - Same as '--system-headers'.
UseColor - Same as '--use-color'.
User - Specifies the name or e-mail of the user
running clang-tidy. This option is used, for
example, to place the correct user name in
TODO() comments in the relevant check.
WarningsAsErrors - Same as '--warnings-as-errors'.
The effective configuration can be inspected using --dump-config:
$ clang-tidy --dump-config
---
Checks: '-*,some-check'
WarningsAsErrors: ''
HeaderFileExtensions: ['', 'h','hh','hpp','hxx']
ImplementationFileExtensions: ['c','cc','cpp','cxx']
HeaderFilterRegex: ''
FormatStyle: none
InheritParentConfig: true
User: user
CheckOptions:
some-check.SomeOption: 'some value'

exit status and sets to be non zero if it found
potential bugs or zero otherwise. (default: False)
--exclude <directory>
Do not run static analyzer against files found in this
directory. (You can specify this option multiple
times.) Could be useful when project contains 3rd
party libraries. (default: [])
--analyze-headers Also analyze functions in #included files. By default,
such functions are skipped unless they are called by
functions within the main source file. (default:
False)
output control options:

--internal-stats Generate internal analyzer statistics. (default:
False)
--maxloop, -maxloop <loop count>
Specify the number of times a block can be visited
before giving up. Increase for more comprehensive
coverage at a cost of speed. (default: None)
--store, -store <model>
Specify the store model used by the analyzer. 'region'
specifies a field- sensitive store model. 'basic'
which is far less precise but can more quickly analyze
code. 'basic' was the default store model for
checker-0.221 and earlier. (default: None)
--constraints, -constraints <model>
Specify the constraint engine used by the analyzer.
Specifying 'basic' uses a simpler, less powerful
constraint model used by checker-0.160 and earlier.
(default: None)
--analyzer-config, -analyzer-config <options>
Provide options to pass through to the analyzer's
-analyzer-config flag. Several options are separated
with comma: 'key1=val1,key2=val2' Available options:
stable-report-filename=true or false (default) Switch
the page naming to: report-<filename>-<function/method
name>-<id>.html instead of report-XXXXXX.html
(default: None)
--force-analyze-debug-code
Tells analyzer to enable assertions in code even if
they were disabled during compilation, enabling more
precise results. (default: False)
checker options:
--load-plugin, -load-plugin <plugin library>
Loading external checkers using the clang plugin
interface. (default: None)
--enable-checker, -enable-checker <checker name>
Enable specific checker. (default: None)
--disable-checker, -disable-checker <checker name>
Disable specific checker. (default: None)
--help-checkers A default group of checkers is run unless explicitly
disabled. Exactly which checkers constitute the
default group is a function of the operating system in
use. These can be printed with this flag. (default:
False)
--help-checkers-verbose
Print all available checkers and mark the enabled
ones. (default: False)
cross translation unit analysis:
--ctu Perform cross translation unit (ctu) analysis (both
collect and analyze phases) using default <ctu-dir>
for temporary output. At the end of the analysis, the
temporary directory is removed. (default: None)
--ctu-dir <ctu-dir> Defines the temporary directory used between ctu
phases. (default: ctu-dir)
--ctu-collect-only Perform only the collect phase of ctu. Keep <ctu-dir>
for further use. (default: None)
--ctu-analyze-only Perform only the analyze phase of ctu. <ctu-dir>
should be present and will not be removed after
analysis. (default: None)
--use-extdef-map-cmd <path>
'analyze-build' uses the 'clang-extdef-mapping'
executable relative to itself for generating external
definition maps for static analysis. One can override
this behavior with this option by using the 'clang-
extdef-mapping' packaged with Xcode (on OS X) or from
the PATH. (default: clang-extdef-mapping)

-p <string> - Build path
-p <build-path> is used to read a compile command database.
For example, it can be a CMake build directory in which a file named
compile_commands.json exists (use -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
CMake option to get this output). When no build path is specified,
a search for compile_commands.json will be attempted through all
parent paths of the first input file . See:
https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html for an
example of setting up Clang Tooling on a source tree.
<source0> ... specify the paths of source files. These paths are
looked up in the compile command database. If the path of a file is
absolute, it needs to point into CMake's source tree. If the path is
relative, the current working directory needs to be in the CMake
source tree and the file must be in a subdirectory of the current
working directory. "./" prefixes in the relative files will be
automatically removed, but the rest of a relative path must be a
suffix of a path in the compile command database.

--verbose, -v Enable verbose output from 'intercept-build'. A second,
third and fourth flags increases verbosity. (default:
0)
--cdb <file> The JSON compilation database. (default:
compile_commands.json)
--override-compiler Always resort to the compiler wrapper even when better
intercept methods are available. (default: False)
--use-cc <path> When 'intercept-build' analyzes a project by
interposing a compiler wrapper, which executes a real
compiler for compilation and do other tasks (record the
compiler invocation). Because of this interposing,
'intercept-build' does not know what compiler your
project normally uses. Instead, it simply overrides the
CC environment variable, and guesses your default
compiler. If you need 'intercept-build' to use a
specific compiler for *compilation* then you can use
this option to specify a path to that compiler.
(default: cc)
--use-c++ <path> This is the same as "--use-cc" but for C++ code.
(default: c++)
advanced options:
--append Extend existing compilation database with new entries.
Duplicate entries are detected and not present in the
final output. The output is not continuously updated,
it's done when the build command finished. (default:
False)

OPTIONS:
-analyze-headers
Also analyze functions in #included files. By default, such functions
are skipped unless they are called by functions within the main source file.
--force-analyze-debug-code
Tells analyzer to enable assertions in code even if they were disabled
during compilation to enable more precise results.
-o <output location>
Specifies the output directory for analyzer reports. Subdirectories will be
created as needed to represent separate "runs" of the analyzer. If this
option is not specified, a directory is created in /tmp (TMPDIR on Mac OS X)
to store the reports.
-h
--help
Display this message.
-k
--keep-going
Add a "keep on going" option to the specified build command. This option
currently supports make and xcodebuild. This is a convenience option; one
can specify this behavior directly using build options.
--keep-cc
Do not override CC and CXX make variables. Useful when running make in
autoconf-based (and similar) projects where configure can add extra flags
to those variables.
--html-title [title]
--html-title=[title]
Specify the title used on generated HTML pages. If not specified, a default
title will be used.
--show-description
Display the description of defects in the list
-sarif
By default the output of scan-build is a set of HTML files. This option
outputs the results in SARIF format.
-plist
By default the output of scan-build is a set of HTML files. This option
outputs the results as a set of .plist files.
-plist-html
By default the output of scan-build is a set of HTML files. This option
outputs the results as a set of HTML and .plist files.
--status-bugs
By default, the exit status of scan-build is the same as the executed build
command. Specifying this option causes the exit status of scan-build to be 1
if it found potential bugs and the exit status of the build itself otherwise.
--exclude <path>
Do not run static analyzer against files found in this
directory (You can specify this option multiple times).
Could be useful when project contains 3rd party libraries.
--use-cc [compiler path]
--use-cc=[compiler path]
scan-build analyzes a project by interposing a "fake compiler", which
executes a real compiler for compilation and the static analyzer for analysis.
Because of the current implementation of interposition, scan-build does not
know what compiler your project normally uses. Instead, it simply overrides
the CC environment variable, and guesses your default compiler.
In the future, this interposition mechanism to be improved, but if you need
scan-build to use a specific compiler for *compilation* then you can use
this option to specify a path to that compiler.
If the given compiler is a cross compiler, you may also need to provide
--analyzer-target option to properly analyze the source code because static
analyzer runs as if the code is compiled for the host machine by default.
--use-c++ [compiler path]
--use-c++=[compiler path]
This is the same as "--use-cc" but for C++ code.
--analyzer-target [target triple name for analysis]
--analyzer-target=[target triple name for analysis]
This provides target triple information to clang static analyzer.
It only changes the target for analysis but doesn't change the target of a
real compiler given by --use-cc and --use-c++ options.
-v
Enable verbose output from scan-build. A second and third '-v' increases
verbosity.
-V
--view
View analysis results in a web browser when the build completes.
--generate-index-only <output location>
Do not perform the analysis, but only regenerate the index.html file
from existing report.html files. Useful for making a custom Static Analyzer
integration into a build system that isn't otherwise supported by scan-build.
ADVANCED OPTIONS:
-no-failure-reports
Do not create a 'failures' subdirectory that includes analyzer crash reports
and preprocessed source files.
-stats
Generates visitation statistics for the project being analyzed.
-maxloop <loop count>
Specify the number of times a block can be visited before giving up.
Default is 4. Increase for more comprehensive coverage at a cost of speed.
-internal-stats
Generate internal analyzer statistics.
--use-analyzer [Xcode|path to clang]
--use-analyzer=[Xcode|path to clang]
scan-build uses the 'clang' executable relative to itself for static
analysis. One can override this behavior with this option by using the
'clang' packaged with Xcode (on OS X) or from the PATH.
--keep-empty
Don't remove the build results directory even if no issues were reported.
--override-compiler
Always resort to the ccc-analyzer even when better interposition methods
are available.

Provide options to pass through to the analyzer's -analyzer-config flag.
Several options are separated with comma: 'key1=val1,key2=val2'
Available options:
* stable-report-filename=true or false (default)
Switch the page naming to:
report-<filename>-<function/method name>-<id>.html
instead of report-XXXXXX.html

BUILD OPTIONS
You can specify any build option acceptable to the build command.
EXAMPLE
scan-build -o /tmp/myhtmldir make -j4
The above example causes analysis reports to be deposited into a subdirectory
of "/tmp/myhtmldir" and to run "make" with the "-j4" option. A different
subdirectory is created each time scan-build analyzes a project. The analyzer
should support most parallel builds, but not distributed builds.

[--help-checkers-verbose]
...
positional arguments:
build Command to run.
options:
-h, --help show this help message and exit
--verbose, -v Enable verbose output from 'scan-build-py'. A second,
third and fourth flags increases verbosity. (default:
0)
--override-compiler Always resort to the compiler wrapper even when better
intercept methods are available. (default: False)
--use-cc <path> When 'scan-build-py' analyzes a project by interposing
a compiler wrapper, which executes a real compiler for
compilation and do other tasks (record the compiler
invocation). Because of this interposing, 'scan-build-
py' does not know what compiler your project normally
uses. Instead, it simply overrides the CC environment
variable, and guesses your default compiler. If you
need 'scan-build-py' to use a specific compiler for
*compilation* then you can use this option to specify
a path to that compiler. (default: cc)
--use-c++ <path> This is the same as "--use-cc" but for C++ code.
(default: c++)
--intercept-first Run the build commands first, intercept compiler calls
and then run the static analyzer afterwards. Generally
speaking it has better coverage on build commands.
With '--override-compiler' it use compiler wrapper,
but does not run the analyzer till the build is
finished. (default: False)
--status-bugs The exit status of 'scan-build-py' is the same as the
executed build command. This option ignores the build
exit status and sets to be non zero if it found
potential bugs or zero otherwise. (default: False)
--exclude <directory>
Do not run static analyzer against files found in this
directory. (You can specify this option multiple
times.) Could be useful when project contains 3rd
party libraries. (default: [])
--analyze-headers Also analyze functions in #included files. By default,
such functions are skipped unless they are called by
functions within the main source file. (default:
False)
output control options:
--output, -o <path> Specifies the output directory for analyzer reports.
Subdirectory will be created if default directory is
targeted. (default: /tmp)
--keep-empty Don't remove the build results directory even if no
issues were reported. (default: False)
--html-title <title> Specify the title used on generated HTML pages. If not
specified, a default title will be used. (default:
None)
--plist, -plist Cause the results as a set of .plist files. (default:
html)
--plist-html, -plist-html
Cause the results as a set of .html and .plist files.
(default: html)
--plist-multi-file, -plist-multi-file
Cause the results as a set of .plist files with extra
information on related files. (default: html)
--sarif, -sarif Cause the results as a result.sarif file. (default:
html)
--sarif-html, -sarif-html
Cause the results as a result.sarif file and .html
files. (default: html)
advanced options:
--use-analyzer <path>
'scan-build-py' uses the 'clang' executable relative
to itself for static analysis. One can override this
behavior with this option by using the 'clang'
packaged with Xcode (on OS X) or from the PATH.
(default: clang-21)
--no-failure-reports, -no-failure-reports
Do not create a 'failures' subdirectory that includes
analyzer crash reports and preprocessed source files.
(default: True)
--stats, -stats Generates visitation statistics for the project.
(default: False)
--internal-stats Generate internal analyzer statistics. (default:
False)
--maxloop, -maxloop <loop count>
Specify the number of times a block can be visited
before giving up. Increase for more comprehensive
coverage at a cost of speed. (default: None)
--store, -store <model>
Specify the store model used by the analyzer. 'region'
specifies a field- sensitive store model. 'basic'
which is far less precise but can more quickly analyze
code. 'basic' was the default store model for
checker-0.221 and earlier. (default: None)
--constraints, -constraints <model>
Specify the constraint engine used by the analyzer.
Specifying 'basic' uses a simpler, less powerful
constraint model used by checker-0.160 and earlier.
(default: None)
--analyzer-config, -analyzer-config <options>
Provide options to pass through to the analyzer's
-analyzer-config flag. Several options are separated
with comma: 'key1=val1,key2=val2' Available options:
stable-report-filename=true or false (default) Switch
the page naming to: report-<filename>-<function/method
name>-<id>.html instead of report-XXXXXX.html
(default: None)
--force-analyze-debug-code
Tells analyzer to enable assertions in code even if
they were disabled during compilation, enabling more
precise results. (default: False)
checker options:
--load-plugin, -load-plugin <plugin library>
Loading external checkers using the clang plugin
interface. (default: None)
--enable-checker, -enable-checker <checker name>
Enable specific checker. (default: None)
--disable-checker, -disable-checker <checker name>
Disable specific checker. (default: None)
--help-checkers A default group of checkers is run unless explicitly
disabled. Exactly which checkers constitute the
default group is a function of the operating system in
use. These can be printed with this flag. (default:
False)
--help-checkers-verbose
Print all available checkers and mark the enabled
ones. (default: False)

lldb --arch x86_64 /path/to/program program argument -- --arch armv7
For convenience, passing the executable after -- is also supported.
lldb --arch x86_64 -- /path/to/program program argument --arch armv7
Passing one of the attach options causes lldb to immediately attach to the
given process.
lldb -p <pid>
lldb -n <process-name>
Passing --repl starts lldb in REPL mode.
lldb -r
Passing --core causes lldb to debug the core file.
lldb -c /path/to/core
Command options can be combined with these modes and cause lldb to run the
specified commands before or after events, like loading the file or crashing,
in the order provided on the command line.
lldb -O 'settings set stop-disassembly-count 20' -o 'run' -o 'bt'
lldb -S /source/before/file -s /source/after/file
lldb -K /source/before/crash -k /source/after/crash
Note: In REPL mode no file is loaded, so commands specified to run after
loading the file (via -o or -s) will be ignored.

<https://msdn.microsoft.com/en-us/library/7ykb2k5f> for the general de-
scription.
llvm-lib has the following extensions:
* Bitcode files in symbol tables. llvm-lib includes symbols from both
bitcode files and regular object files in the symbol table.
* Creating thin archives. The /llvmlibthin option causes llvm-lib to cre-
ate thin archive that contain only the symbol table and the header for
the various members. These files are much smaller, but are not compati-
ble with link.exe (lld can handle them).
