Chris Lattner 9637d5b22e Teach X86ISelLowering that the second result of X86ISD::UMUL is a flags ... result. This allows us to compile: void *test12(long count) { return new int[count]; } into: test12: movl $4, %ecx movq %rdi, %rax mulq %rcx movq $-1, %rdi cmovnoq %rax, %rdi jmp __Znam ## TAILCALL instead of: test12: movl $4, %ecx movq %rdi, %rax mulq %rcx seto %cl testb %cl, %cl movq $-1, %rdi cmoveq %rax, %rdi jmp __Znam Of course it would be even better if the regalloc inverted the cmov to 'cmovoq', which would eliminate the need for the 'movq %rdi, %rax'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120936 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-05 07:49:54 +00:00
