  Hash : d57e0db3
  Message : Remove separate compilerdebug.h in favor of debug.h This unifies the behavior across the compiler and rest of ANGLE - for example, one can use #define ANGLE_TEST_CONFIG to disable UNIMPLEMENTED asserts in both the compiler and the rest of ANGLE. Compiler traces from asserts also go to the same TRACE_OUTPUT_FILE as other traces instead of being directed through ParseContext. The compiler build already includes the common sources, so no changes to build config are needed. The original version of this change was reverted due to release mode build issues. This version adds UNUSED_ASSERTION_VARIABLE where needed. TEST=angle_unittests, angle_end2end_tests, dEQP-GLES3.functional.shaders.* BUG=angleproject:983 Change-Id: I36929020a04251b8bc834fbb3c069e10128c3082 Reviewed-on: https://chromium-review.googlesource.com/267411 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Olli Etuaho <oetuaho@nvidia.com> Tested-by: Olli Etuaho <oetuaho@nvidia.com>
