  Message : Define ANGLE_IS_64_BIT_CPU in common/platform.h. This is more reliable and reduces reliance on build flags. Vendoring into Firefox, it's not trivial to replicate build flags, but C++-native checks always work. Bug: angleproject:6186 Change-Id: Idafd4ef1954efbfa79eae86cddfaa8f2e3992296 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3036589 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
