From //third_party/blink/renderer/config.gni:40
|
|
|
|
How many symbols to include in the build of blink. This affects
|
|
the performance of the build since the symbols are large and dealing with
|
|
them is slow.
|
|
2 means regular build with symbols.
|
|
1 means medium symbols, usually enough for backtraces only. Symbols with
|
|
internal linkage (static functions or those in anonymous namespaces) may not
|
|
appear when using this level. On some platforms (including Windows)
|
|
filenames and line numbers will be included. Information about types and
|
|
locals is not included.
|
|
0 means minimal symbols, which on some platforms (including Windows) may

|
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

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.

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.

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.
|

Current value = false
|

From //out/Linux/args.gn:17
|

Overridden from the default = false
|
|
From //build/config/c++/c++.gni:41
|
|
|
|
When set, enables libc++ debug mode with iterator debugging.
|
|
|
|
Iterator debugging is generally useful for catching bugs. But it can
|
|
introduce extra locking to check the state of an iterator against the state
|
|
of the current object. For iterator- and thread-heavy code, this can
|
|
significantly slow execution - two orders of magnitude slowdown has been
|
|
seen (crbug.com/903553) and iterator debugging also slows builds by making
|
|
generation of snapshot_blob.bin take ~40-60 s longer. Therefore this
|
|
defaults to off.

Enables out-of-process printing. While this definition matches

Current value (from the default) = false

From //third_party/perfetto/gn/perfetto.gni:257

The traced_probes daemon is very Linux-specific, as it depends on ftrace and

|
various /proc interfaces. There is no point making its code platform-neutral
|
|
as it won't do anything useful on Windows.
|
|
The only reason why we still build it on Mac OS is to be able to run the
|
|
unittests there and making dev on mac less cumbersome. The traced_probes
|
|
code happens to build cleanly and for now the mainteinance cost on Mac is

extremely low.

exclude_unwind_tables

Current value = true
|

From //out/Linux/args.gn:15
|
|
Overridden from the default = true
|
|
From //build/config/compiler/compiler.gni:120
|
|
|
|
Exclude unwind tables by default for official builds as unwinding can be
|
|
done from stack dumps produced by Crashpad at a later time "offline" in the
|
|
crash server. Since this increases binary size, we don't recommend including
|
|
them in shipping builds.
|
|
For unofficial (e.g. development) builds and non-Chrome branded (e.g. Cronet
|
|
which doesn't use Crashpad, crbug.com/479283) builds it's useful to be able
|
|
to unwind at runtime.
|
|
Include the unwind tables on Android even for official builds, as otherwise
|
|
the crash dumps generated by Android's debuggerd are largely useless, and
|
|
having this additional mechanism to understand issues is particularly helpful
|
|
to WebView.

|
|
extended_tracing_enabled
|

Current value (from the default) = false
|

ffmpeg_use_unsafe_atomics
|
|
Current value (from the default) = false
|
|
From //third_party/ffmpeg/ffmpeg_options.gni:62
|
|
|
|
Set to true to force the use of ffmpeg's stdatomic fallback code. This code
|
|
is unsafe and does not implement atomics properly. https://crbug.com/161723.
|
|
|
|
Windows and GCC prior to 4.9 lack stdatomic.h.
|
|
|
|
This is also useful for developers who use icecc, which relies upon
|
|
clang's -frewrite-includes flag which is broken with #include_next
|
|
directives as used in chromium's clang stdatomic.h.

Current value (from the default) = ""

From //build/config/gcc/BUILD.gn:19
|

When non empty, overrides the target rpath value. This allows a user to
|
|
make a Chromium build where binaries and shared libraries are meant to be
|
|
installed into separate directories, like /usr/bin/chromium and
|
|
/usr/lib/chromium for instance. It is useful when a build system that
|
|
generates a whole target root filesystem (like Yocto) is used on top of gn,
|
|
especially when cross-compiling.
|
|
Note: this gn arg is similar to gyp target_rpath generator flag.

|
include_ash_ambient_animation_resources
|
|
Current value (from the default) = false
|
|
From //ash/ambient/resources/resources.gni:16
|
|
|
|
Build flag to include resources for the animated screensaver in ash builds.
|
|
|
|
Currently, these resources are included by default for internal ChromeOS
|
|
builds as both conditions below are prerequisites for downloading Lottie
|
|
ambient mode resources from CIPD in the DEPS file.
|
|
|
|
May be overridden locally to false for testing purposes if desired.
|
|
|
|
include_transport_security_state_preload_list
|
|
Current value (from the default) = true
|
|
From //net/features.gni:36
|
|
|
|
Includes the transport security state preload list. This list includes
|
|
mechanisms (e.g. HSTS, HPKP) to enforce trusted connections to a significant
|
|
set of hardcoded domains. While this list has a several hundred KB of binary
|
|
size footprint, this flag should not be disabled unless the embedder is
|
|
willing to take the responsibility to make sure that all important
|
|
connections use HTTPS.

init_stack_vars
|
|
Current value (from the default) = true
|
|
From //build/config/compiler/BUILD.gn:140
|
|
|
|
Initialize all local variables with a pattern. This flag will fill
|
|
uninitialized floating-point types (and 32-bit pointers) with 0xFF and the
|
|
rest with 0xAA. This makes behavior of uninitialized memory bugs consistent,
|
|
recognizable in the debugger, and crashes on memory accesses through
|
|
uninitialized pointers.

From //out/Linux/args.gn:12
|
|
Overridden from the default = false
|
|
From //build/config/BUILDCONFIG.gn:136
|
|
|
|
Set to enable the official build level of optimization. This has nothing
|
|
to do with branding, but enables an additional level of optimization above
|
|
release (!is_debug). This might be better expressed as a tri-state
|
|
(debug, release, official) but for historical reasons there are two
|
|
separate flags.
|
|
|
|
IMPORTANT NOTE: (!is_debug) is *not* sufficient to get satisfying
|
|
performance. In particular, DCHECK()s are still enabled for release builds,
|
|
which can halve overall performance, and do increase memory usage. Always
|

is_perfetto_embedder
|
|
Current value (from the default) = false
|
|
From //third_party/perfetto/gn/perfetto.gni:87
|
|
|
|
This is for override via `gn args` (e.g. for tools/gen_xxx). Embedders

From //base/BUILD.gn:60
|
|
|
|
Unsafe developer build. Has developer-friendly features that may weaken or

From //build/config/c++/c++.gni:55
|
|
|
|
WARNING: Setting this to a non-default value is highly discouraged.
|
|
If true, libc++ will be built as a shared library; otherwise libc++ will be
|
|
linked statically. Setting this to something other than the default is
|
|
unsupported and can be broken by libc++ rolls. Note that if this is set to
|
|
true, you must also set libcxx_abi_unstable=false, which is bad for
|
|
performance and memory use.

|
From //third_party/libyuv/BUILD.gn:19
|
|
|
|
When building a shared library using a target in WebRTC or

limit_android_deps
|
|
Current value (from the default) = false
|
|
From //build_overrides/build.gni:35
|
|
|
|
Limits the defined //third_party/android_deps targets to only "buildCompile"
|
|
and "buildCompileNoDeps" targets. This is useful for third-party
|
|
repositories which do not use JUnit tests. For instance,

|
|
link_pulseaudio
|
|
Current value (from the default) = false
|
|
From //media/media_options.gni:19
|
|
|
|
Allows distributions to link pulseaudio directly (DT_NEEDED) instead of

|
If this is set to true, we use the revision in the llvm repo to determine

the CLANG_REVISION to use, instead of the version hard-coded into
|
|
//tools/clang/scripts/update.py. This should only be used in

|
From //media/media_options.gni:247
|
|
|
|
The process that the mojo MediaService runs in. By default, all services
|
|
registered in |mojo_media_services| are hosted in the MediaService, with the
|
|
exception that when |enable_library_cdms| is true, the "cdm" service will
|
|
run in a separate CdmService in the CDM (utility) process, while other
|
|
|mojo_media_services| still run in the MediaService in the process specified
|
|
by "mojo_media_host".

monolithic_binaries
|
|
Current value (from the default) = false
|
|
From //third_party/perfetto/gn/perfetto.gni:214
|
|
|
|
Only for local development. When true the binaries (perfetto, traced, ...)
|
|
are monolithic and don't use a common shared library. This is mainly to
|
|
avoid LD_LIBRARY_PATH dances when testing locally.
|
|
On Windows we default to monolithic executables, because pairing
|
|
dllexport/import adds extra complexity for little benefit. Te only reason
|
|
for monolithic_binaries=false is saving binary size, which matters mainly on
|
|
Android. See also comments on PERFETTO_EXPORT_ENTRYPOINT in compiler.h.

|
|
From //third_party/perfetto/gn/perfetto.gni:229
|
|
|
|
Whether DCHECKs should be enabled or not. Values: "on" | "off" | "".
|
|
By default ("") DCHECKs are enabled only:
|
|
- If DCHECK_ALWAYS_ON is defined (which is mainly a Chromium-ism).
|
|
- On debug builds (i.e. if NDEBUG is NOT defined) but only in Chromium,
|
|
Android and standalone builds.
|
|
- On all other builds (e.g., SDK) it's off regardless of NDEBUG (unless
|

|
From //build/config/linux/pkg_config.gni:33
|
|
|
|
A pkg-config wrapper to call instead of trying to find and call the right
|
|
pkg-config directly. Wrappers like this are common in cross-compilation
|
|
environments.
|
|
Leaving it blank defaults to searching PATH for 'pkg-config' and relying on

|
|
Current value (from the default) = false
|
|
From //base/third_party/symbolize/BUILD.gn:13
|
|
|
|
Stack traces will not include function names. Instead they will contain
|
|
file and offset information that can be used with
|
|
tools/valgrind/asan/asan_symbolize.py. By piping stderr through this script,
|
|
and also enabling symbol_level = 2, you can get much more detailed stack

traces with file names and line numbers, even in non-ASAN builds.

From //build/config/features.gni:26
|
|
|
|
Enables proprietary codecs and demuxers; e.g. H264, AAC, MP3, and MP4.
|
|
We always build Google Chrome and Chromecast with proprietary codecs.
|
|
|
|
Note: this flag is used by WebRTC which is DEPSed into Chrome. Moving it

|
previous slot (or in metadata if a slot starts on the page boundary), as
|
|
opposed to the beginning of the slot.
|
|
- enable_backup_ref_ptr_slow_checks: enable additional safety checks that
|
|
are too expensive to have on by default.
|
|
- enable_dangling_raw_ptr_checks: enable checking raw_ptr do not become

remoting_webrtc_verbose_logging
|
|
Current value (from the default) = false
|

From //remoting/build/config/remoting_logging.gni:13
|
|
|
|
Enabling this will cause WebRTC's LS_INFO and LS_VERBOSE (level 1)
|
|
messages to appear in the debug log output. Note that WebRTC's
|
|
"VERBOSE1" messages are very spammy and it is impossible to
|
|
separately filter LS_INFO and LS_VERBOSE messages (see
|
|
third_party/webrtc_overrides/rtc_base/). So a separate GN option is
|
|
provided here, to allow this logging to be quickly enabled for Debug
|
|
or Release builds.

Chromium currently has a Rust toolchain for Android and Linux, but
|
|
if you wish to experiment on more platforms you can use this
|
|
argument to specify an alternative toolchain.
|

This should be an absolute path to a directory

rustc_can_link
|
|
Current value (from the default) = true
|
|
From //build/config/rust.gni:73
|
|
|
|
Rust code may end up being linked into a final executable by:
|
|
* rustc (which calls lld)
|
|
* our pre-existing C++ linker invocations
|
|
At the moment, this first pipeline is incompatible with the ldflags we use
|
|
for thin LTO, due to some problem in escaping gn rules. There's a further
|
|
problem with -lunwind on Android.
|
|
However, Rust code is still useful if it's contributing to our existing
|
|
C++ linker invocations, so this doesn't disable Rust entirely. It does
|
|
disable Rust unit test executables, so we do need to fix this.

Whether we should consider the profile we're using to be accurate. Accurate

|
|
You can set the variable 'use_internal_isolated_origins' to true to use this

|
|
From //build/config/compiler/compiler.gni:42
|
|
|
|
Set to true to use lld, the LLVM linker.
|
|
In late bring-up on macOS (see docs/mac_lld.md).
|
|
Tentatively used on iOS, except in cronet builds (cronet still supports
|
|
32-bit builds, which lld doesn't support).
|

use_lto_in_rustc_linking
|
|
Current value (from the default) = false
|

From //build/config/rust.gni:55
|
|
|
|
Use LTO when using rustc to link binaries. Experimental. Currently incompatible
|
|
with the options we use in our C++ toolchain to split LTO units.
|
|
This has no effect on the production of normal Chrome binaries, which are
|
|
linked by clang/lld rather than rustc.

true to use the Google-internal file containing official API keys
|
|
for enterprise connector partners even in a developer build. Setting this
|

internal file is missing.
|
|
|
|
Note that official builds always behave as if the variable

use_official_google_api_keys
|
|
Current value (from the default) = ""
|
|
From //google_apis/BUILD.gn:33
|
|
|
|
You can set the variable 'use_official_google_api_keys' to true
|
|
to use the Google-internal file containing official API keys
|
|
for Google Chrome even in a developer build. Setting this
|
|
variable explicitly to true will cause your build to fail if the

internal file is missing.
|
|
|
|
The variable is documented here, but not handled in this file;
|
|
see //google_apis/determine_use_official_keys.gypi for the

implementation.
|
|
|
|
Set the variable to false to not use the internal file, even when

it exists in your checkout.
|
|
|
|
Leave it unset or set to "" to have the variable
|
|
implicitly set to true if you have

Whether PartitionAlloc should be available for use or not.
|
|
true makes PartitionAlloc linked to the executable or shared library and

|
makes it available for use. It doesn't mean that the default allocator
|
|
is PartitionAlloc, which is governed by |use_allocator|.
|
|
|
|
This flag is currently set to false only on Cronet bots, because Cronet
|
|
doesn't use PartitionAlloc at all, and doesn't wish to incur the library

From //build/config/compiler/BUILD.gn:80
|
|

but some sanitizers are known to require it, like CFI diagnostics
|
|
and UBsan variants.
|
|
|
|
use_runtime_vlog
|
|
Current value (from the default) = true
|
|
From //build/config/logging.gni:31
|
|
|
|
Use runtime vlog everywhere except for ash-chrome.
|
|
When `use_runtime_vlog` is true,
|
|
command line switch `--vmodule=xxx` or `--v=x` could be used to
|
|
control vlog level at runtime.
|
|
when `use_runtime_volog` is false,
|
|
verbose log level is controlled by `ENABLE_VLOG_LEVEL` macro. VLOG(n)
|
|
is kept and generate output if `n` is less than or equal to the vlog
|
|
level defined by the macro.
|
|
Command line switch `--vmodule=xxx`, or `--v=x` would have no effect.
|
|
|
|
Runtime vlog is used everywhere except on ash-chrome.
|
|
Ash-chrome has a few vmodule patterns that need to be used indefinitely
|
|
to investigate problems from logs in feedback reports. These vmodule
|
|
patterns are using too much cpu cycles (see http://crbug/489441). Turning
|
|
off runtime vlog and using build time vlog would avoid paying that cpu tax
|
|
and have a nice side effect of a smaller production binary.

use_swiftshader_with_subzero
|
|
Current value (from the default) = true
|
|
From //third_party/swiftshader/src/Reactor/reactor.gni:27
|

|
|
Subzero produces much smaller binaries, so always use it when available,

use_system_freetype
|
|
Current value (from the default) = false
|
|
From //build/config/freetype/freetype.gni:13
|
|
|
|
Blink needs a recent and properly build-configured FreeType version to
|
|
support OpenType variations, color emoji and avoid security bugs. By default
|
|
we ship and link such a version as part of Chrome. For distributions that
|
|
prefer to keep linking to the version the system, FreeType must be newer
|
|
than version 2.7.1 and have color bitmap support compiled in. WARNING:
|

use_system_harfbuzz

Current value (from the default) = false

From //third_party/harfbuzz-ng/harfbuzz.gni:11
|
|
|
|
Blink uses a cutting-edge version of Harfbuzz; most Linux distros do not
|
|
contain a new enough version of the code to work correctly. However,
|
|
ChromeOS chroots (i.e, real ChromeOS builds for devices) do contain a
|
|
new enough version of the library, and so this variable exists so that

ChromeOS can build against the system lib and keep binary sizes smaller.

use_system_libsync
|
|
Current value (from the default) = false
|
|
From //third_party/libsync/BUILD.gn:13
|
|
|
|
Controls whether the build should use the version of libsync
|

library shipped with the system. In release builds of Chrome OS we
|
|
use the system version, but when building on dev workstations we
|
|
bundle it because Ubuntu doesn't ship a usable version.

Current value (from the default) = false
|
|
From //build/config/compiler/BUILD.gn:149
|
|
|
|
This argument is to control whether enabling text section splitting in the
|
|
final binary. When enabled, the separated text sections with prefix
|
|
'.text.hot', '.text.unlikely', '.text.startup' and '.text.exit' will not be
|
|
merged to '.text' section. This allows us to identify the hot code section
|
|
('.text.hot') in the binary which may be mlocked or mapped to huge page to
|
|
reduce TLB misses which gives performance improvement on cpu usage.
|
|
The gold linker by default has text section splitting enabled.

used for profile-guided optimization of builtins.
|
|
|
|
To do profile-guided optimizations of builtins:
|
|
1. Build with v8_enable_builtins_profiling = true
|
|
2. Run your chosen workload with the --turbo-profiling-log-builtins flag.
|
|
For Chrome, the invocation might look like this:
|
|
chrome --no-sandbox --disable-extensions
|
|
--js-flags="--turbo-profiling-log-builtins --logfile=path/to/v8.log"
|
|
"http://localhost/test-suite"
|
|
3. Run tools/get_hints.py to produce the branch hints, selecting min_count
|
|
and threshold_ratio as you wish.
|
|
4. Optionally repeat steps 2-3 for additional workloads, and use
|
|
tools/combine_hints.py to combine the hints produced in step 3 into a
|
|
single file.
|
|
5. Build again with v8_builtins_profiling_log_file set to the file created
|
|
in step 3 or 4.

|
v8_target_cpu
|
|
Current value (from the default) = ""
|
|
From //build/config/v8_target_cpu.gni:33
|
|
|
|
This arg is used when we want to tell the JIT-generating v8 code
|
|
that we want to have it generate for an architecture that is different
|
|
than the architecture that v8 will actually run on; we then run the
|
|
code under an emulator. For example, we might run v8 on x86, but
|
|
generate arm code and run that under emulation.
|
|
|
|
This arg is defined here rather than in the v8 project because we want
|
|
some of the common architecture-specific args (like arm_float_abi or
|
|
mips_arch_variant) to be set to their defaults either if the current_cpu
|
|
applies *or* if the v8_current_cpu applies.
|
|
|
|
As described below, you can also specify the v8_target_cpu to use
|
|
indirectly by specifying a `custom_toolchain` that contains v8_$cpu in the
|
|
name after the normal toolchain.
|
|
|
|
For example, `gn gen --args="custom_toolchain=...:clang_x64_v8_arm64"`
|
|
is equivalent to setting --args=`v8_target_cpu="arm64"`. Setting
|
|
`custom_toolchain` is more verbose but makes the toolchain that is
|
|
(effectively) being used explicit.
|
|
|
|
v8_target_cpu can only be used to target one architecture in a build,
|
|
so if you wish to build multiple copies of v8 that are targeting
|
|
different architectures, you will need to do something more
|
|
complicated involving multiple toolchains along the lines of
|
|
custom_toolchain, above.

|
|
used for development. Only has an effect on Windows builds.
