Chris Lattner 97f37a439c Fix a problem that Nate noticed that boils down to an over conservative check ... in the code that does "select C, (X+Y), (X-Y) --> (X+(select C, Y, (-Y)))". We now compile this loop: LBB1_1: ; no_exit add r6, r2, r3 subf r3, r2, r3 cmpwi cr0, r2, 0 addi r7, r5, 4 lwz r2, 0(r5) addi r4, r4, 1 blt cr0, LBB1_4 ; no_exit LBB1_3: ; no_exit mr r3, r6 LBB1_4: ; no_exit cmpwi cr0, r4, 16 mr r5, r7 bne cr0, LBB1_1 ; no_exit into this instead: LBB1_1: ; no_exit srawi r6, r2, 31 add r2, r2, r6 xor r6, r2, r6 addi r7, r5, 4 lwz r2, 0(r5) addi r4, r4, 1 add r3, r3, r6 cmpwi cr0, r4, 16 mr r5, r7 bne cr0, LBB1_1 ; no_exit git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26356 91177308-0d34-0410-b5e6-96231b3b80d8		2006-02-24 18:05:58 +00:00
