[X86] Autogenerate complete checks. NFC llvm-svn: 350012 2018-12-23 09:54:41 +08:00			`; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py`
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.

Custom lower the memory barrier instructions and add support for lowering without sse2. Add a couple of new testcases. Fixes a few libgomp tests and latent bugs. Remove a few todos. llvm-svn: 109078 2010-07-22 10:48:34 +08:00
