[PATCH] clang compatibility: fpu options

[Volodymyr Turanskyy]

Hi Joel,

Let me fix the commit messages.

Clang does not have vfpxd - vfpv3xd might be the closest, however we believe that it is not needed for clang at all, so it is skipped.

Same with missing commit.

Does the clang assembler have a directive for vfpxd? If I am reading the patch correctly, it just drops the directive rather than replacing it.

Hi,

Following up on the RFC [1], please find attached a patch that adds a check to avoid extra assembler directives that are not compatible with clang and are not needed by clang.
