[PATCH] D11148: [ARM] Implement -Wa, -mfpu and friends for assemblers

[Renato Golin]

rengolin added a comment.

So, what do you suggest?

A warning might break -Werror builds that already depend on this option to work.

Checking the last option is not possible using filters, since they have different types.

Replacing -Wa,-mfpu by -mfpu Arg inplace (to allow for last-of filtering) is not possible, since the ArgList is const.

When there is only -Wa and no -mfpu, not doing anything gets the wrong behaviour.

Any other ideas?

cheers,
