The code that disables Arm and Intel assembly code under MSan is duplicated in cpu_support.h and planar_functions.h. This CL does not address the code duplication. Bug: b:407277484, b:407278016, b:407278132 Change-Id: If70fd8d3382916041d75efabcc84010ea3f1e60e Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/6430806 Commit-Queue: Frank Barchard <fbarchard@chromium.org> Reviewed-by: Frank Barchard <fbarchard@chromium.org>
