David Majnemer c2a990bc00 InstCombine: (icmp eq B, 0) | (icmp ult A, B) -> (icmp ule A, B-1) ... This transform allows us to turn IR that looks like: %1 = icmp eq i64 %b, 0 %2 = icmp ult i64 %a, %b %3 = or i1 %1, %2 ret i1 %3 into: %0 = add i64 %b, -1 %1 = icmp uge i64 %0, %a ret i1 %1 which means we go from lowering: cmpq %rsi, %rdi setb %cl testq %rsi, %rsi sete %al orb %cl, %al ret to lowering: decq %rsi cmpq %rdi, %rsi setae %al ret llvm-svn: 185677		2013-07-05 00:31:17 +00:00
