[llvm-commits] Patch for Bug 13556: ARM AsmPrinter doesn't support %H modifier in inline ASM

[Weiming Zhao]

Hi,

 

I'm attaching a patch to fix bug 13556:
http://llvm.org/bugs/show_bug.cgi?id=13556

 

In ARM inline AMM, %H represents the highest-numbered register of a pair. 

Routines like atomic read of 64-bit values needs this modifier.

Currently, ARMAsmPrinter doesn't support this modifier.

 

The patch fixes this issue.

Please feel free to review it.

 

Thanks,

Weiming
