Description Renato Golin 2013-12-06 09:02:55 PST 
In order to simplify execution, reduce external tool-chain dependencies and facilitate the cross-compilation process, we propose to enable the integrated assembler by default.

There were a few critical bugs open that would stop this from happening, but they were all fixed by now, so we propose that, for the remaining non-critical bugs, we allow a -no-integrated-as flag.

Bug #18080 was the last of the required ones by my count.

Other bugs that will need to be implemented to make the IAS complete are:
#8721
#15172
#17769
#18019

But they're not required to turn the IAS on by default.

Checking on the LLVM Linux list for possible problems...
Comment 3 Renato Golin 2013-12-10 04:00:43 PST 
Build systems call the compiler to assemble files, so we need to support some of the assembler flags GCC does to make a seamless change between GAS and Clang:

clang-3.5: error: unsupported argument '-funwind-tables' to option 'Xassembler'
clang-3.5: error: unsupported argument '-march=armv7-a' to option 'Wa,'
