| # This file contains the build configurations of Skia that we use for testing on the CI. |
| # These allow a short-form reference for our supported combinations of build features. |
| # https://bazel.build/docs/bazelrc#config |
| # |
| # For most build configurations, we will want to set the --cc_output_directory_tag [1] |
| # with a unique identifier per configuration name. |
| # |
| # By default, Bazel's "unique target BuildConfiguration" [2] incorporates the compilation_mode, |
| # the target platform, and some suffixes to avoid Bazel-caused and user-caused conflicts. [3] [4] |
| # For example, a default output directory might look like "k8-fastbuild-ST-6a54c1377847". |
| # Inside this output directory is a subfolder for the target (e.g. executable) name. |
| # |
| # Note that multiple definitions of a config are allowed - in this event, they are added together. |
| # This is handy if we need to comment on why certain settings are necessary. Otherwise, escaping |
| # the trailing newline (and thus having a multi-line definition) is preferred for brevity. |
| # |
| # Notably, the flags that we turn on and off via //bazel/common_config_settings do not affect |
| # the output directory. The output directory is used to store compiled object files (.o files) |
| # and generated dependency files (e.g. the output of clang --write-dependencies [5]), so having |
| # these be overwritten unnecessarily will slow down incremental rebuilds when switching between |
| # building different configurations of the same targets. |

| # --platforms refers to the target for which we are compiling. By setting the target to be a |
| # platform which has our own custom constraint_setting and constraint_value |
| # (skia_hermetic_toolchain=use_hermetic_toolchain), this causes Bazel to resolve the toolchain |
| # to be our hermetic one because our hermetic toolchains have that same constraint set in their |
| # target_compatible_with list. |
