> To expand a bit on Eric's response, the intent here is *not* to make Bazel
a supported build system for LLVM or to replace CMake (which I believe the
proposal makes clear), but rather to enable Bazel usage and shared
configuration for people and projects that already use it. I do not expect
that Bazel will cover all the use cases currently supported by LLVM CMake
any time soon (ever?).I don't work on Bazel itself, so have no insight on
the support plan for those architectures. Only developers interested in
working with Bazel would be expected to use or update the configuration, so
lack of support for specific architectures should not affect things, I
think.
