2006-11-08optimize single MBB loops better. In particular, produce:Chris Lattner
LBB1_57: #bb207.i movl 72(%esp), %ecx movb (%ecx,%eax), %cl movl 80(%esp), %edx movb %cl, 1(%edx,%eax) incl %eax cmpl $143, %eax jne LBB1_57 #bb207.i jmp LBB1_64 #cond_next255.i intead of: LBB1_57: #bb207.i movl 72(%esp), %ecx movb (%ecx,%eax), %cl movl 80(%esp), %edx movb %cl, 1(%edx,%eax) incl %eax cmpl $143, %eax je LBB1_64 #cond_next255.i jmp LBB1_57 #bb207.i This eliminates a branch per iteration of the loop. This hurted PPC particularly, because the extra branch meant another dispatch group for each iteration of the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31530 91177308-0d34-0410-b5e6-96231b3b80d8
