1# This file contains the build configurations of Skia that we use for testing on the CI. 2# These allow a short-form reference for our supported combinations of build features. 3# https://bazel.build/docs/bazelrc#config 4# 5# For most build configurations, we will want to set the --cc_output_directory_tag [1] 6# with a unique identifier per configuration name. 7# 8# By default, Bazel's "unique target BuildConfiguration" [2] incorporates the compilation_mode, 9# the target platform, and some suffixes to avoid Bazel-caused and user-caused conflicts. [3] [4] 10# For example, a default output directory might look like "k8-fastbuild-ST-6a54c1377847". 11# Inside this output directory is a subfolder for the target (e.g. executable) name. 12# 13# Note that multiple definitions of a config are allowed - in this event, they are added together. 14# This is handy if we need to comment on why certain settings are necessary. Otherwise, escaping 15# the trailing newline (and thus having a multi-line definition) is preferred for brevity. 16# 17# Notably, the flags that we turn on and off via //bazel/common_config_settings do not affect 18# the output directory. The output directory is used to store compiled object files (.o files) 19# and generated dependency files (e.g. the output of clang --write-dependencies [5]), so having 20# these be overwritten unnecessarily will slow down incremental rebuilds when switching between 21# building different configurations of the same targets. 22# 23# [1] https://bazel.build/reference/command-line-reference#flag--cc_output_directory_tag 24# [2] https://bazel.build/docs/output_directories#layout-diagram 25# [3] https://github.com/bazelbuild/bazel/blob/ad37a3748c78e0ee903b56366322c70ab8b22187/CODEBASE.md#the-structure-of-the-output-directory 26# [4] https://github.com/bazelbuild/bazel/blob/e0e589658463beb9605030b4820dcc97e6a36f48/src/main/java/com/google/devtools/build/lib/analysis/config/OutputDirectories.java#L198-L236 27# [5] https://clang.llvm.org/docs/ClangCommandLineReference.html#dependency-file-generation 28 29# ============================================================================= 30# Targets (what to build for) 31# ============================================================================= 32 33# --platforms refers to the target for which we are compiling. By setting the target to be a 34# platform which has our own custom constraint_setting and constraint_value 35# (skia_hermetic_toolchain=use_hermetic_toolchain), this causes Bazel to resolve the toolchain 36# to be our hermetic one because our hermetic toolchains have that same constraint set in their 37# target_compatible_with list. 38build:for_linux_x64_debug
