[llvm-commits] CVS: llvm/test/Regression/CodeGen/PowerPC/2007-01-15-AsmDialect.ll

[Bill Wendling]

Changes in directory llvm/test/Regression/CodeGen/PowerPC:

2007-01-15-AsmDialect.ll added (r1.1)
---
Log message:

Fix for PR1095: http://llvm.org/PR1095 :
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.
