Chris Lattner 82e14db9a9 Add a hack to avoid some horrible code in some cases by always emitting ... token chains first. For this C function: int test() { int i; for (i = 0; i < 100000; ++i) foo(); } Instead of emitting this (condition before call) .LBB_test_1: ; no_exit addi r30, r30, 1 lis r2, 1 ori r2, r2, 34464 cmpw cr2, r30, r2 bl L_foo$stub bne cr2, .LBB_test_1 ; no_exit Emit this: .LBB_test_1: ; no_exit bl L_foo$stub addi r30, r30, 1 lis r2, 1 ori r2, r2, 34464 cmpw cr0, r30, r2 bne cr0, .LBB_test_1 ; no_exit Which makes it so we don't have to save/restore cr2 in the prolog/epilog of the function. This also makes the code much more similar to what the pattern isel produces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23135 91177308-0d34-0410-b5e6-96231b3b80d8		2005-08-29 23:21:29 +00:00
