[cfe-dev] clang test failure: CodeGen/atomic.c

[Ted Kremenek]

I'm at ToT for llvm and clang, and I am seeing the following test  
failure on Mac OS X in the CodeGen module:

(kremenek at grue:CodeGen)$ ../TestRunner.sh atomic.c
******************** TEST 'atomic.c' FAILED! ********************
Command:
  clang atomic.c -emit-llvm -o - > Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.las.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.lss.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.min.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.max.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.umin.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.umax.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.swap.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.lcs.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.and.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.or.i32 Output/atomic.c.out.tmp1 &&
  grep @llvm.atomic.load.xor.i32 Output/atomic.c.out.tmp1
Incorrect Output:
******************** TEST 'atomic.c' FAILED! ********************

Anyone else seeing this?
