1611968 - HOST_OPTIMIZE_FLAGS don't apply to clang-plugin files

Status: NEW

(Firefox Build System :: General, defect, P3)

Description

[(Away)]

I'm trying to change optimization flags on clang-plugin to investigate something. I noticed that changing HOST_OPTIMIZE_FLAGS doesn't affect the flags in the log. Changing MOZ_OPTIMIZE_FLAGS does affect those flags.

According to context.py this is keyed off of CROSS_COMPILE. But I'm not really doing a cross compile, I'm compiling for Windows from Windows, but we still think of clang-plugin as a "host" thing.

As far as I can tell this was the logic in config.mk before, as well. The setup is pretty weird, but you should be able to set HOST_COMPILE_FLAGS['HOST_OPTIMIZE'] in build/clang-plugin/moz.build to the desired value to achieve this.
