X86: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests.

Fix SelectionDAG::ReplaceAllUsesWith to behave correctly when uses are added to the From node while it is processing From's use list, because of automatic local CSE. The fix is to avoid visiting any new uses. Fix a few places in the DAGCombiner that assumed that after a RAUW call, the From node has no users and may be deleted. This fixes PR3018. llvm-svn: 62533 2009-01-20 05:44:21 +08:00

Convert CodeGen//.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( \)\([A-Z0-9_]\):\( \)test\([A-Za-z0-9_-]\):\( \)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen//*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258 2013-07-14 04:38:47 +08:00			`; CHECK-LABEL: test:`
