Benjamin Kramer 7d6fe13efc Add some x86 specific dagcombines for conditional increments. ... (add Y, (sete X, 0)) -> cmp X, 1; adc 0, Y (add Y, (setne X, 0)) -> cmp X, 1; sbb -1, Y (sub (sete X, 0), Y) -> cmp X, 1; sbb 0, Y (sub (setne X, 0), Y) -> cmp X, 1; adc -1, Y for unsigned foo(unsigned a, unsigned b) { if (a == 0) b++; return b; } we now get: foo: cmpl $1, %edi movl %esi, %eax adcl $0, %eax ret instead of: foo: testl %edi, %edi sete %al movzbl %al, %eax addl %esi, %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122364 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-21 21:41:44 +00:00
