* Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵Stephen Lin2013-07-13
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186258 91177308-0d34-0410-b5e6-96231b3b80d8

* fix PR10605 / rdar://9930964 by adding a pretty scary missed check.Chris Lattner2011-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | It's somewhat surprising anything works without this. Before we would compile the testcase into: test: # @test movl $4, 8(%rdi) movl 8(%rdi), %eax orl %esi, %eax cmpl $32, %edx movl %eax, -4(%rsp) # 4-byte Spill je .LBB0_2 now we produce: test: # @test movl 8(%rdi), %eax movl $4, 8(%rdi) orl %esi, %eax cmpl $32, %edx movl %eax, -4(%rsp) # 4-byte Spill je .LBB0_2 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137303 91177308-0d34-0410-b5e6-96231b3b80d8
* Be less aggressive about hinting in RAFast.Jakob Stoklund Olesen2011-06-13
| | | | | | | | | | In particular, don't spill dirty registers only to satisfy a hint. It is not worth it. The attached test case provides an example where the fast allocator would spill a register when other registers are available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132900 91177308-0d34-0410-b5e6-96231b3b80d8
* As Dan pointed out, movzbl, movsbl, and friends are nicer than their aliasBill Wendling2011-04-14
