* * Remove the -stopraise option, which is no longer needed now that we haveChris Lattner2002-09-221-10/+1
| | | | | | | | | | the -debug-pass=Arguments option * Run instcombining BEFORE mem2reg so that getelementptr X, long 0's are cleaned up. This is also important because scalar replacement of aggr. will want instcombine to run before it goes as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3879 91177308-0d34-0410-b5e6-96231b3b80d8
* gcc3.1.1 seems much more selective about what it loads from archives, andVikram S. Adve2002-09-181-2/+2
| | | | | | | | does not link in many passes that are loaded by gcc2.95.3. So use object files instead of archives in many more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3803 91177308-0d34-0410-b5e6-96231b3b80d8
* * No longer need to run die after instcombineChris Lattner2002-09-061-3/+5
| | | | | | | | | * Run new correlated expressions pass * Simplify the CFG (removing dead blocks, merging blocks, eliminating branches on constant booleans, etc) after correlated exprs pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3598 91177308-0d34-0410-b5e6-96231b3b80d8
* - Reformat commentsChris Lattner2002-08-301-18/+19
