Dan Gohman	36a0947820	Eliminate more uses of llvm-as and llvm-dis. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81290 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 23:54:48 +00:00
Dale Johannesen	2cf68d4d23	Adjust XFAIL syntax, maybe that will help. The other ... way worked for me... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69414 91177308-0d34-0410-b5e6-96231b3b80d8	2009-04-18 02:01:23 +00:00
Dale Johannesen	f4948450d1	patch 69408 breaks this by removing the opportunity ... for the optimization it's testing to kick in (although it improves the code, getting rid of all spills). I don't understand the optimization well enough to rescue the test, so XFAILing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69409 91177308-0d34-0410-b5e6-96231b3b80d8	2009-04-18 00:11:50 +00:00
Evan Cheng	276b77e66c	Teach spiller to unfold instructions which modref spill slot when a scratch ... register is available and when it's profitable. e.g. xorq %r12<kill>, %r13 addq %rax, -184(%rbp) addq %r13, -184(%rbp) ==> xorq %r12<kill>, %r13 movq -184(%rbp), %r12 addq %rax, %r12 addq %r13, %r12 movq %r12, -184(%rbp) Two more instructions, but fewer memory accesses. It can also open up opportunities for more optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69341 91177308-0d34-0410-b5e6-96231b3b80d8	2009-04-17 01:29:40 +00:00
