Aarch64 compile inline asm error: unexpected token in argument list

[davidchisnall]

This is a clang bug. I've reported the issue upstream, hopefully it can be fixed in 3.8.

Could you provide a link to the filed issue so that I can monitor it and try to build clang on Aarch64 when it's fixed?

https://llvm.org/bugs/show_bug.cgi?id=25957 Feel free to follow up with more info. I think Tim Northover is responsible for this breakage.

As of version 3.9 (trunk from 03/15/2016) the issue is still there.

Any idea what line in what file in the CLANG source I have to patch to make this work at least for myself?

[davidchisnall]

Look in clang/lib/CodeGen/TargetInfo.cpp. There's a method AArch64TargetCodeGenInfo::getARCRetainAutoreleasedReturnValueMarker(). This should probably be conditional on targeting a Mac runtime, but if you just want something that works for now then simply making it return nullptr should work.

Found it! Awesome! Thank you!!!!!

I believe that this is now fixed in clang.
