| # Defines a Clang-based toolchain. |
| # |
| # Parameters |
| # |
| # toolchain_cpu |
| # Required: Value of "current_cpu" inside this toolchain. |
| # |
| # toolchain_os |
| # Required: Value of "current_os" inside this toolchain. |
| # |
| # toolchain_args |
| # Optional: Scope specifying build arguments to override in this |
| # toolchain context. |
| # NOTE! Do not use this in the toolchain used as the default toolchain. |
| # It will have no effect, and you will be confused. |
| # |
| # use_strip |
| # Required: Whether to strip binaries, leaving unstripped ones |
| # in lib.unstripped and exe.unstripped subdirectories. |
| # |
| # prefix |
| # Optional: The path from which "cc", "cxx", "ar", "ld" and |
| # "strip" will be found (unless overridden). If not given, |
| # prefix defaults to $clang_prefix. |
| # |
| # cc |
| # cxx |
| # ar |
| # ld |
| # strip |
| # Optional: Override default tool names. |
| # |
| # use_ccache, use_goma |
| # Optional: Override the global setting, useful to opt out of |
| # ccache/goma in a particular toolchain. |
| # |
| # deps |
| # Optional: Dependencies of this toolchain. |
| # |
| # propagates_configs |
| # Optional: public_configs should escape this toolchain via deps |
