Chris Lattner 1902ff4d82 This break is bogus and I have no idea why it was there. Basically it prevents ... memoizing code when IV's are used by phinodes outside of loops. In a simple example, we were getting this code before (note that r6 and r7 are isomorphic IV's): li r6, 0 or r7, r6, r6 LBB_test_3: ; no_exit lwz r2, 0(r3) cmpw cr0, r2, r5 or r2, r7, r7 beq cr0, LBB_test_5 ; loopexit LBB_test_4: ; endif addi r2, r7, 1 addi r7, r7, 1 addi r3, r3, 4 addi r6, r6, 1 cmpw cr0, r6, r4 blt cr0, LBB_test_3 ; no_exit Now we get: li r6, 0 LBB_test_3: ; no_exit or r2, r6, r6 lwz r6, 0(r3) cmpw cr0, r6, r5 beq cr0, LBB_test_6 ; loopexit LBB_test_4: ; endif addi r3, r3, 4 addi r6, r2, 1 cmpw cr0, r6, r4 blt cr0, LBB_test_3 ; no_exit this was noticed in em3d. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23602 91177308-0d34-0410-b5e6-96231b3b80d8		2005-10-03 00:37:33 +00:00
