List of variants that will form the basis for variant toolchains. To make use of a variant, set select_variant.
Normally this is not set as a build argument, but it serves to document the available set of variants. See also universal_variants. Only set this to remove all the default variants here. To add more, set extra_variants instead.
Each element of the list is one variant, which is a scope defining:
configs (optional) [list of labels] Each label names a config that will be automatically used by every target built in this variant. For each config ${label}, there must also be a target ${label}_deps, which each target built in this variant will automatically depend on. The variant() template is the recommended way to define a config and its _deps target at the same time.
remove_common_configs (optional) remove_shared_configs (optional) [list of labels] This list will be removed (with -=) from the default_common_binary_configs list (or the default_shared_library_configs list, respectively) after all other defaults (and this variant's configs) have been added.
deps (optional) [list of labels] Added to the deps of every target linked in this variant (as well as the automatic ${label}_deps for each label in configs).
name (required if configs is omitted) [string] Name of the variant as used in select_variant elements' variant fields. It's a good idea to make it something concise and meaningful when seen as e.g. part of a directory name under $root_build_dir. If name is omitted, configs must be nonempty and the simple names (not the full label, just the part after all /s and :s) of these configs will be used in toolchain names (each prefixed by a “-”), so the list of config names forming each variant must be unique among the lists in known_variants + extra_variants.
tags (optional) [list of strings] A list of liberal strings describing properties of the toolchain instances created from this variant scope. See //build/toolchain/variant_tags.gni for the list of available values and their meaning.
toolchain_args (optional) [scope] Each variable defined in this scope overrides a build argument in the toolchain context of this variant.
host_only (optional) target_only (optional) [scope] This scope can contain any of the fields above. These values are used only for host or target, respectively. Any fields included here should not also be in the outer scope.

In protected mode, faults don‘t return as much information so they’re much harder to debug. To work around that, add a mode where protected atoms are executed in non-protected mode and vice-versa.
NOTE: The memory security ranges should also be set (in TrustZone) to the opposite of normal, so that non-protected mode accesses can only access protected memory and vice versa. Also, growable memory faults won't work in this mode, so larger portions of growable memory should precommitted (which is not done by default).

Default Scudo options (before the SCUDO_OPTIONS environment variable is read at runtime). Scudo is the memory allocator in Fuchsia's C library, so this affects all Fuchsia programs. This can be a list of strings or a single string.
This operates similarly to asan_default_options and its cousins for other sanitizers, but is slightly different. If this variable is empty, then no __scudo_default_options function is injected into programs at all. Individual targets can use dependencies on sanitizer_extra_options() targets to cause options to be injected, and that will be compatible with any build-wide settings of scudo_default_options. Programs can define their own __scudo_default_options functions, but doing so will break all builds with this variable is set to nonempty, so any program in the build that needs such a setting (which should be only in tests) can use the sanitizer_extra_options() mechanism instead.

List of “selectors” to request variant builds of certain targets. Each selector specifies matching criteria and a chosen variant. The first selector in the list to match a given target determines which variant is used for that target.
Each selector is either a string or a scope. A shortcut selector is a string; it gets expanded to a full selector. A full selector is a scope, described below.
A string selector can match a name in select_variant_shortcuts. If it‘s not a specific shortcut listed there, then it can be the name of any variant described in known_variants and universal_variants (and combinations thereof). A selector that’s a simple variant name selects for every binary built in the target toolchain: { host=false variant=selector }.
If a string selector contains a slash, then it‘s "shortcut/filename" and selects only the binary in the target toolchain whose output_name matches "filename", i.e. it adds output_name=["filename"] to each selector scope that the shortcut’s name alone would yield.
The scope that forms a full selector defines some of these:
variant (required)
[string or `false`] The variant that applies if this selector
matches. This can be `false` to choose no variant, or a string
that names the variant. See
[`known_variants`](#known_variants) and
[`universal_variants`](#universal_variants).
The rest below are matching criteria. All are optional. The selector matches if and only if all of its criteria match. If none of these is defined, then the selector always matches.
The first selector in the list to match wins and then the rest of the list is ignored. To construct more complex rules, use a blocklist selector with variant=false before a catch-all default variant, or a list of specific variants before a catch-all false variant.
Each “[strings]” criterion is a list of strings, and the criterion is satisfied if any of the strings matches against the candidate string.
host
[boolean] If true, the selector matches in the host toolchain.
If false, the selector matches in the target toolchain.
testonly
[boolean] If true, the selector matches targets with testonly=true.
If false, the selector matches in targets without testonly=true.
target_type
[strings]: `"executable"`, `"loadable_module"`, or `"driver_module"`
output_name
[strings]: target's `output_name` (default: its `target name`)
label
[strings]: target's full label with `:` (without toolchain suffix)
name
[strings]: target's simple name (label after last `/` or `:`)
dir
[strings]: target's label directory (`//dir` for `//dir:name`).

The input to the size checker. The build system will produce a JSON file to be consumed by the size checker, which will check and prevent integration of subsystems that are over their space allocation. The input consists of the following keys:
asset_ext(string array): a list of extensions that should be considered as assets.
asset_limit(number): maximum size (in bytes) allocated for the assets.
core_limit(number): maximum size (in bytes) allocated for the core system and/or services. This is sort of a “catch all” component that consists of all the area / packages that weren't specified in the components list below.
components(object array): a list of component objects. Each object should contain the following keys:
component(string): name of the component.
src(string array): path of the area / package to be included as part of the component. The path should be relative to the obj/ in the output directory. For example, consider two packages foo and far, built to out/.../obj/some_big_component/foo and out/.../obj/some_big_component/bar. If you want to impose a limit on foo, your src will be [“some_big_component/foo”]. If you want to impose a limit on both foo and far, your src will be [“some_big_component”]. If a package has config-data, those prebuilt blobs actually live under the config-data package. If you wish to impose a limit of those data as well, you should add “build/images/config-data/$for_pkg” to your src. The $for_pkg corresponds to the $for_pkg field in config.gni.
limit(number): maximum size (in bytes) allocated for the component.
Example: size_checker_input = { asset_ext = [ “.ttf” ] asset_limit = 10240 core_limit = 10240 components = [ { component = “Foo” src = [ “topaz/runtime/foo_runner” ] limit = 10240 }, { component = “Bar” src = [ “build/images” ] limit = 20480 }, ] }

This should never be set as a build argument. It exists only to be set in toolchain_args. See //build/toolchain/clang_toolchain.gni for details. This variable is a scope giving details about the current toolchain: toolchain_variant.base [label] The “base” toolchain for this variant, often the right thing to use in comparisons, not current_toolchain. This is the toolchain actually referenced directly in GN source code. If the current toolchain is not shlib_toolchain or a variant toolchain, this is the same as current_toolchain. In one of those derivative toolchains, this is the toolchain the GN code probably thought it was in. This is the right thing to use in a test like toolchain_variant.base == target_toolchain, rather rather than comparing against current_toolchain. toolchain_variant.name [string] The name of this variant, as used in variant fields in select_variant clauses. In the base toolchain and its shlib_toolchain, this is "". toolchain_variant.suffix [string] This is “-${toolchain_variant.name}”, "" if name is empty. toolchain_variant.is_pic_default [bool] This is true in shlib_toolchain. toolchain_variant.tags [list of strings] A list of liberal strings, each one describing a property of this toolchain instance. See //build/toolchain/variant_tags.gni for more details. toolchain_variant.configs [list of configs] A list of configs that are added after the default ones to all linkable targets for this toolchain() instance. toolchain_variant.prefix_configs [list of configs] A list of configs that are added before the default ones to all linkable targets for this toolchain() instance. toolchain_variant.remove_common_configs [list of configs] A list of configs that are removed from all linkable targets for this toolchain() instance. Useful when one of the default configs must not be used. toolchain_variant.remove_shared_configs [list of configs] Same a remove_common_configs, but only applies to non-executable (e.g. shared_library()) targets. toolchain_variant.instrumented [boolean] A convenience flag that is true iff “instrumented” is part of toolchain_variant.tags. toolchain_variant.with_shared [boolean] True iff this toolchain() instance has a secondary toolchain to build ELF shared-library code.
The other fields are the variant's effects as defined in known_variants.

Default UndefinedBehaviorSanitizer options (before the UBSAN_OPTIONS environment variable is read at runtime). This can be set as a build argument to affect most “ubsan” variants in $variants (which see), or overridden in $toolchain_args in one of those variants. This can be a list of strings or a single string.
Note that even if this is empty, programs in this build cannot define their own __ubsan_default_options C function. Instead, they can use a sanitizer_extra_options() target in their deps and then any options injected that way can override that option's setting in this list.

If you add package labels to this variable, the packages will be included in the ‘universe’ package set, which represents all software that is produced that is to be published to a package repository or to the SDK by the build.
