Chris Lattner aa43e9f73b Fix a bug which caused us to never be able to use signed comparisons for ... equality comparisons of a constant. This allows us to codegen the 'sintzero' loop in PR1288 as: LBB1_1: ;cond_next li r4, 0 addi r2, r2, 1 stw r4, 0(r3) addi r3, r3, 4 cmpwi cr0, r2, -1 bne cr0, LBB1_1 ;cond_next instead of: LBB1_1: ;cond_next addi r2, r2, 1 li r4, 0 xoris r5, r2, 65535 stw r4, 0(r3) addi r3, r3, 4 cmplwi cr0, r5, 65535 bne cr0, LBB1_1 ;cond_next This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74 instructions out of kc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35590 91177308-0d34-0410-b5e6-96231b3b80d8		2007-04-02 05:59:42 +00:00
