* Fixed issue that broke ssa.Tanya Lattner2005-05-111-1/+24
| | | | llvm-svn: 21878
* fix some GCC 4 warningsChris Lattner2005-05-111-0/+2
| | | | llvm-svn: 21877
* Added support for decomposing constant expressions containing shr and shlJohn Criswell2005-05-111-0/+24
| | | | | | | instructions. Review of this commit would be greatly appreciated. llvm-svn: 21876
* Fix lowering of ctlz, so now UnitTests/2005-05-11-Popcount-ffs-fls passesChris Lattner2005-05-111-40/+26
| | | | | | with the CBE llvm-svn: 21875
* Fix lowering of cttz to work with signed valuesChris Lattner2005-05-111-5/+4
| | | | llvm-svn: 21874
* fix and concisify intinsic lowering for ctpop. Unfortunately, this codeChris Lattner2005-05-111-167/+61
| | | | | | looks completely untested. :( llvm-svn: 21873
* Fix the last remaining bug preventing us from switching the X86 BE overChris Lattner2005-05-111-30/+68
| | | | | | | | | from the simple isel to the pattern isel. This forces inserted libcalls to serialize against other function calls, which was breaking UnitTests/2005-05-12-Int64ToFP. Hopefully this will fix issues on other targets as well. llvm-svn: 21872
* Do not memoize ADJCALLSTACKDOWN nodes, provide a method to hack on them.Chris Lattner2005-05-111-3/+24
