[llvm-commits] [patch][libLTO/gold] Make it possible to set the flags passed to the assembler

[Rafael Espindola]

The attached patch makes it possible to pass extra flags to the
assembler. The gnu assembler needs extra flags like

* --32/--64 to select x86 or x86-64
* -mfpu on arm to select which fp instructions are available

I could just implement this logic in libLTO, but since a similar logic
exists in clang that didn't look like the right approach. One day I
should implement a use-gold-plugin option in clang and it would be
nice for clang to be able to just pass those flags to libLTO.

Cheers,
