2004-04-02Rewrite the indvars pass to use the ScalarEvolution analysis.Chris Lattner
This also implements some new features for the indvars pass, including linear function test replacement, exit value substitution, and it works with a much more general class of induction variables and loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12620 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-02Only strip symbols if emitting bytecode to the assembly file.Brian Gaeke
Move lowerselect pass to come after preselection. Move machine code construction and stack slots pass to come right before instruction selection. This is to help fix perlbmk. Update comments. Make the sequence of passes in addPassesToJITCompile look more like the sequence of passes in addPassesToEmitAssembly, including support for -print-machineinstrs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12614 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-02Fix two pretty serious bugs:Chris Lattner
1. Each time the loop extractor extracted a loop, we would leak a module. 2. When we extracted a loop, we didn't add the new function to the list of miscompiled functions. Thus if the bug was in a loop nest and we extracted it, we could actually *LOSE THE BUG*, which is very bad. With these patches, bugpoint has successfully found a bug for me in a function with several nested loops, and cut it down to just one of them. :) :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12605 91177308-0d34-0410-b5e6-96231b3b80d8

2004-03-31Codegen FP select instructions into X86 conditional moves. Annoyingly enoughChris Lattner
the X86 does not support a full set of fp cmove instructions, so we can't always fold the condition into the select. :( Yuck. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12577 91177308-0d34-0410-b5e6-96231b3b80d8
