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 getNode to allow a vector for the shift amount for shifts of vectors. Fix the shift amount when unrolling a vector shift into scalar shifts. Fix problem in getShuffleScalarElt where it assumes that the input of a bit convert must be a vector. llvm-svn: 60740 2008-12-09 13:46:39 +08:00

Make x86 test actually test x86 code generation. Fix the construct on ARM, which was breaking by coincidence, and add a similar testcase for ARM. llvm-svn: 79719 2009-08-22 11:13:10 +08:00			`%shr = lshr <2 x i64> %val, < i64 2, i64 3 >`
