* This is a bulk commit that implements the following primary improvements:Chris Lattner2005-01-011-78/+268
| | | | | | | | | | | | | | | | | | | | | | | * We can now fold cast instructions into select instructions that have at least one constant operand. * We now optimize expressions more aggressively based on bits that are known to be zero. These optimizations occur a lot in code that uses bitfields even in simple ways. * We now turn more cast-cast sequences into AND instructions. Before we would only do this if it if all types were unsigned. Now only the middle type needs to be unsigned (guaranteeing a zero extend). * We transform sign extensions into zero extensions in several cases. This corresponds to these test/Regression/Transforms/InstCombine testcases: 2004-11-22-Missed-and-fold.ll and.ll: test28-29 cast.ll: test21-24 and-or-and.ll cast-cast-to-and.ll zeroext-and-reduce.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19220 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a FIXME: Select instructions on longs were miscompiled.Chris Lattner2005-01-011-19/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While we're at it, improve codegen of select instructions. For this testcase: int %test(bool %C, int %A, int %B) { %D = select bool %C, int %A, int %B ret int %D } We used to generate this code: _test: cmpwi cr0, r3, 0 bne .LBB_test_2 ; .LBB_test_1: ; b .LBB_test_3 ; .LBB_test_2: ; or r5, r4, r4 .LBB_test_3: ; or r3, r5, r5 blr Now we emit: _test: cmpwi cr0, r3, 0 bne .LBB_test_2 ; .LBB_test_1: ; or r4, r5, r5 .LBB_test_2: ; or r3, r4, r4 blr -Chris git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19214 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | SimplifyCFG is one of those passes that we use for final cleanup: it should not rely on other passes to clean up its garbage.
