[llvm-commits] [llvm-gcc-4.2] r47801 - /llvm-gcc-4.2/trunk/gcc/llvm-convert.cpp

[Evan Cheng]

This breaks x86-64. libgomp/critical compiles to:

define void @GOMP_critical_name_start(i8** %pptr) nounwind  {
entry:
   ...
         tail call i64 @llvm.atomic.lcs.i64( i8** %pptr, i64 0, i64  
%tmp1314 )           ; <i64>:0 [#uses=1]
  ...
         ret void
}
