Set to "ccache", "icecc" or "distcc".  Probably doesn't work on windows.

chrome_enable_logging_by_default
Current value (from the default) = false
From //chrome/common/features.gni:31

Enables the build to have logging enabled by default.
This is intended for use only in developer builds.

chrome_orderfile_path
Current value (from the default) = “”
From //build/config/compiler/BUILD.gn:190

chrome_pgo_phase
Current value = 0
From //out/arm/args.gn:5
Overridden from the default = 0
From //build/config/compiler/pgo/pgo.gni:20

Specify the current PGO phase.
Here's the different values that can be used:
    0 : Means that PGO is turned off.
    1 : Used during the PGI (instrumentation) phase.
    2 : Used during the PGO (optimization) phase.
PGO profiles are generated from `dcheck_always_on = false` builds. Mixing
those profiles with `dcheck_always_on = true` builds can cause the compiler
to think some code is hotter than it actually is, potentially causing very
bad compile times.

chrome_public_manifest_package
Current value (from the default) = “org.chromium.chrome.stable”
From //chrome/android/BUILD.gn:75

Android package name to use when compiling the public chrome targets
(chrome_public_apk, monochrome_public_apk, etc. as well as the
*_bundle variants). This is particularly useful when using
monochrome_public_apk for WebView development, as the OS only accepts
WebView providers which declare one of a handful of package names. See
https://chromium.googlesource.com/chromium/src/+/HEAD/android_webview/docs/build-instructions.md#Changing-package-name
for details.

chrome_root_store_policy_supported
Current value (from the default) = false
From //chrome/common/features.gni:39

Platforms where the ChromeRootStoreEnabled enterprise policy is
supported. This must must match the supported_on/future_on list of the
policy in policy_templates.json and be a subset of the
chrome_root_store_supported platforms.
See https://crbug.com/1228958. This can be removed when the Chrome Root
Store is unconditionally enabled on all platforms.

chrome_root_store_supported
Current value (from the default) = false
From //net/features.gni:48

Platforms for which certificate verification can be performed using the
builtin cert verifier with the Chrome Root Store, and this can be
configured using the ChromeRootStoreUsed feature flag. When the feature
flag is false, verification may be done with the platform verifier or the
builtin verifier using platform roots, depending on the platform.
See https://crbug.com/1216547 for status.

chrome_wide_echo_cancellation_supported
Current value (from the default) = false
From //media/media_options.gni:315

Currently it is available on Win, Mac and Linux, since it requires the audio
service to run in a separate process.

chromeos_afdo_platform
Current value (from the default) = “atom”
From //build/config/compiler/BUILD.gn:106

This configuration is used to select a default profile in Chrome OS based on
the microarchitectures we are using. This is only used if
clang_use_default_sample_profile is true and clang_sample_profile_path is
empty.

chromeos_is_browser_only
Current value (from the default) = false
From //build/config/chromeos/ui_mode.gni:19

Deprecated, use is_lacros.

This controls UI configuration for Chrome.
If this flag is set, we assume Chrome runs on Chrome OS devices, using
Wayland (instead of X11).

TODO(crbug.com/1052397):
Define chromeos_product instead, which takes either "browser" or "ash".
Re-define the following variables as:
is_lacros = chromeos_product == "browser"
is_ash = chromeos_product == "ash"

clang_base_path
Current value (from the default) = “//third_party/llvm-build/Release+Asserts”
From //build/config/clang/clang.gni:17

clang_diagnostic_dir
Current value (from the default) = “…/…/tools/clang/crashreports”
From //build/config/compiler/compiler.gni:127

From //build/config/compiler/BUILD.gn:109

Emit debug information for profiling wile building with clang.

clang_sample_profile_path
Current value (from the default) = “”
From //build/config/compiler/BUILD.gn:90

Path to an AFDO profile to use while building with clang, if any. Empty
implies none.

clang_use_chrome_plugins
Current value (from the default) = true
From //build/config/clang/clang.gni:14

clang_use_default_sample_profile
Current value (from the default) = true
From //build/config/compiler/BUILD.gn:99

Turn this on to have the compiler output extra timing information.

compute_build_timestamp
Current value (from the default) = “compute_build_timestamp.py”
From //build/timestamp.gni:17

This should be the filename of a script that prints a single line
containing an integer that's a unix timestamp in UTC.
This timestamp is used as build time and will be compiled into
other code.

This argument may look unused. Before removing please check with the
chromecast team to see if they still use it internally.

compute_inputs_for_analyze
Current value (from the default) = false
From //build/config/compute_inputs_for_analyze.gni:13

Enable this flag when running "gn analyze".

This causes some gn actions to compute inputs immediately (via exec_script)
where they would normally compute them only when executed (and write them to
a depfile).

This flag will slow down GN, but is required for analyze to work properly.

concurrent_links
Current value (from the default) = -1
From //build/toolchain/concurrent_links.gni:23

Limit the number of concurrent links; we often want to run fewer
links at once than we do compiles, because linking is memory-intensive.
The default to use varies by platform and by the amount of memory
available, so we call out to a script to get the right value.

content_shell_major_version
Current value (from the default) = “999”
From //content/shell/BUILD.gn:42

content_shell_product_name
Current value (from the default) = “Content Shell”
From //content/shell/BUILD.gn:40

From //content/shell/BUILD.gn:41

coverage_instrumentation_input_file
Current value (from the default) = “”
From //build/config/coverage/coverage.gni:36

The path to the coverage instrumentation input file should be a source root
absolute path (e.g. //out/Release/coverage_instrumentation_input.txt), and
the file consists of multiple lines where each line represents a path to a
source file, and the paths must be relative to the root build directory.
e.g. ../../base/task/post_task.cc for build directory 'out/Release'.

NOTE that this arg will be non-op if use_clang_coverage is false.

cppgc_allow_allocations_in_prefinalizers
Current value (from the default) = false
From //v8/BUILD.gn:303

Enable allocations during prefinalizer invocations.

cppgc_enable_2gb_cage

Current value (from the default) = “socket”
From //third_party/crashpad/crashpad/util/net/tls.gni:19

crashpad_use_boringssl_for_http_transport_socket
Current value (from the default) = false
From //third_party/crashpad/crashpad/util/net/tls.gni:30

cros_board
Current value (from the default) = “”
From //build/config/chromeos/args.gni:8

This is used only by Simple Chrome to bind its value to test-runner scripts
generated at build-time.

cros_sdk_version
Current value (from the default) = “”
From //build/config/chromeos/args.gni:12

Similar to cros_board above, this used only by test-runner scripts in
Simple Chrome.

Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:50

Enable Dawn's ASSERTs even in release builds

dawn_complete_static_libs
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:55

Should the Dawn static libraries be fully linked vs. GN's default of
treating them as source sets. This is useful for people using Dawn
standalone to produce static libraries to use in their projects.

Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:58

Enables the compilation of Dawn's D3D12 backend

dawn_enable_desktop_gl
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:69

Enables the compilation of Dawn's OpenGL backend
(best effort, non-conformant)

dawn_enable_error_injection
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:84

dawn_enable_metal
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:61

Enables the compilation of Dawn's Metal backend

dawn_enable_null
Current value (from the default) = true
From //third_party/dawn/scripts/dawn_features.gni:65

Enables the compilation of Dawn's Null backend
(required for unittests, obviously non-conformant)

From //third_party/dawn/scripts/dawn_features.gni:98

dawn_enable_vulkan_validation_layers
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:93

dawn_use_angle
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:40

TODO(dawn:1545): Re-enable dawn_use_angle on Android. In non-component
builds, this is adding a dependency on ANGLE's libEGL.so and
libGLESv2.so, apparently without regard for the use_static_angle=true
GN variable. Chromium's linker on Android disallows production of more
than one shared object per target (?).

dawn_use_swiftshader
Current value (from the default) = false
From //third_party/dawn/scripts/dawn_features.gni:45

Enables SwiftShader as the fallback adapter. Requires dawn_swiftshader_dir
to be set to take effect.
TODO(dawn:1536): Enable SwiftShader for Android.

dcheck_always_on
Current value = false
From //out/arm/args.gn:6
Overridden from the default = false
