Chris: On my _local_ x86_64 Ubuntu 7.10 machine, the shift_ops.ll is an unexpected success (i.e., "grep -w shlh %t1.s | count 9" succeeds.) I get the same unexpected success on my x86_64 Mac 10.4.11. On the x86_64 buildbot, the same test fails. The culprit is grep, evidently. It's just that simple. I suspect there's not really an issue with endianness, since all the test does is (a) gener...

...t entirely sure how to categorize this particular problem, but it's clearly platform test related: "grep -w" appears to operate differently on the x86_64 linux buildbot versus my local Mac OS 10.4.11 and Ubuntu x86_64. In the CellSPU's shift_ops.ll test case, "grep -w shlh" returns the correct 9 expected occurances, whereas the x86_64 buildbot finds 10. Any suggestions for a workaround, other than to ditch using "grep -w"? -scooter

Does the asm output differ, or does grep output itself differ on these two platforms, with the same asm input file? I just took the .s output file from a run on an x86/Linux box, and tested it with grep o...
