[llvm-commits] PATCH: llvm-gcc option to emit "va_arg" instruction

[David Meyer]

Hello LLVM,

Attached is a patch to add the option "-fuse-llvm-va-arg" to llvm-gcc. The
default behavior remains unchanged.

When this option is passed, invocations of __builtin_va_arg always emit the
LLVM va_arg instruction instead of being lowered to target-specific
operations.

Visual diff is available at: http://codereview.chromium.org/3694002/show

The code in this patch was originally provided by Alan Donovan of Google,
with contributions from Rafael Espindola and myself.

Thank you,
 David M
