Define a new intrinsic, @llvm.debugger. It will be similar to __builtin_trap(), but it generates int3 on x86 instead of ud2. llvm-svn: 156593 2012-05-11 02:19:32 +02:00			`; RUN: llc < %s -march=x86 -mcpu=yonah \| FileCheck %s`

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 2013-07-13 22:38:47 +02:00			`; CHECK-LABEL: test0:`
