2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-07fix a serious pessimization that Tron on IRC pointed out where we wouldChris Lattner
"boolify" pointers, generating really awful code because getting the pointer value requires a load itself.

2009-03-06While thinking about the one-definition-rule and tryingDuncan Sands
to find a tiny mouse hole to squeeze through, it struck me that globals without a name can be considered internal since they can't be referenced from outside the current module. This patch makes GlobalOpt give them internal linkage. Also done for aliases even though they always have names, since in my opinion anonymous aliases should be allowed for consistency with global variables and functions. So if that happens one day, this code is ready! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66267 91177308-0d34-0410-b5e6-96231b3b80d8

If non constant local GV named A is used by a constant local GV named B (e.g. llvm.dbg.variable) and B is not used by anyone else then eliminate A as well as B. In other words, debug info should not interfere in removal of unused GV. --This life, and those below, will be ignored-- M test/Transforms/GlobalOpt/2009-03-03-dbg.ll M lib/Transforms/IPO/GlobalOpt.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66167 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-14rewrite OptimizeAwayTrappingUsesOfLoads to 1) avoid a temporaryChris Lattner
vector and extraneous loop over it, 2) not delete globals used by phis/selects etc which could actually be useful. This fixes PR3321. Many thanks to Duncan for narrowing this down. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62201 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-02Reimplement the old and horrible bison parser for .ll files with a niceChris Lattner
and clean recursive descent parser. This change has a couple of ramifications: 1. The parser code is about 400 lines shorter (in what we maintain, not including what is autogenerated). 2. The code should be significantly faster than the old code because we don't have to work around bison's poor handling of datatypes with ctors/dtors. This also makes the code much more resistant to memory leaks. 3. We now get caret diagnostics from the .ll parser, woo. 4. The actual diagnostics emited from the parser are completely different so a bunch of testcases had to be updated. 5. I now disallow "%ty = type opaque %ty = type i32". There was no good reason to support this, it was just an accident of the old implementation. I have no reason to think that anyone is actually using this. 6. The syntax for sticking a global variable has changed to make it unambiguous. I don't think anyone is depending on this since only clang supports this and it is not solid yet, so I'm not worried about anything breaking. 7. This gets rid of the last use of bison, and along with it the .cvs files. I'll prune this from the makefiles as a subsequent commit. There are a few minor cleanups that can be done after this commit (suggestions welcome!) but this passes dejagnu testing and is ready for its time in the limelight. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61558 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-17Enhance heap sra to be substantially more aggressive w.r.t PHIChris Lattner
nodes. This allows it to do fairly general phi insertion if a load from a pointer global wants to be SRAd but the load is used by (recursive) phi nodes. This fixes a pessimization on ppc introduced by Load PRE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61123 91177308-0d34-0410-b5e6-96231b3b80d8
