2005-08-30Make sure the selector emits register register copies with flag operandsChris Lattner
linking them to calls when appropriate, this prevents the scheduler from pulling these copies away from the call. This fixes Ptrdist/yacr2 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23143 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-29Implement DYNAMIC_STACKALLOC, wrap some long linesChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23136 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-29Add a hack to avoid some horrible code in some cases by always emittingChris Lattner
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

2005-08-27Implement PR614:Reid Spencer
These changes modify the makefiles so that the output of flex and bison are placed in the SRC directory, not the OBJ directory. It is intended that they be checked in as any other LLVM source so that platforms without convenient access to flex/bison can be compiled. From now on, if you change a .y or .l file you *must* also commit the generated .cpp and .h files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23115 91177308-0d34-0410-b5e6-96231b3b80d8
