2005-08-02This code was very close, but not quite right. It did not take intoChris Lattner
consideration the case where a reference in an unreachable block could occur. This fixes Transforms/SimplifyCFG/2005-08-01-PHIUpdateFail.ll, something I ran into while bugpoint'ing another pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22584 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-02When the user hits ctrl-c, bugpoint should attempt to stop reduction asChris Lattner
quickly as possible and output what it has so far. If they hit it twice, bugpoint is killed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22579 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-02200.sixtrack prints FP numbers with a very strange notation that uses DChris Lattner
instead of E for exponentials (e.g. 1.234D-43). Add support for this notation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22574 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22567 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-01ConstantInt::get only works for arguments < 128.Chris Lattner
SimplifyLibCalls probably has to be audited to make sure it does not make this mistake elsewhere. Also, if this code knows that the type will be unsigned, obviously one arm of this is dead. Reid, can you take a look into this further? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22566 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-30Change the fp to integer code to not perform 2-byte stores followed byChris Lattner
1 byte loads and other operations. This is bad for store-forwarding on common CPUs. We now do this: fnstcw WORD PTR [%ESP] mov %AX, WORD PTR [%ESP] instead of: fnstcw WORD PTR [%ESP] mov %AL, BYTE PTR [%ESP + 1] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22559 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-30Commit a new LoopStrengthReduce pass that can use scalar evolutions andNate Begeman
target data to decide which loop induction variables to strength reduce and how to do so. This work is mostly by Chris Lattner, with tweaks by me to get it working on some of MultiSource. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22558 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-30Break SCEVExpander out of IndVarSimplify into its own .h/.cpp file so thatNate Begeman
other passes may use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22557 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-30Use a custom expander for all FP to int conversions, as the X86 only hasChris Lattner
FP-to-int-in-memory: this exposes the load from the stored slot to the selection dag, allowing it to be folded into other operaions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22556 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-29Implement a FIXME: move a bunch of cruft for handling FP_TO_*INT operationsChris Lattner
that the X86 does not support to the legalizer. This allows it to be better optimized, etc, and will help with SSE support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22551 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-28instead of having all conversions be handled by one case value, and then haveChris Lattner
subcases inside, break things out earlier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22546 91177308-0d34-0410-b5e6-96231b3b80d8
