2009-09-03Revert 80959. It isn't sufficient to solve the full problem. And itDan Gohman
introduced regressions in the Ocaml bindings tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80969 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Remove the API for creating ConstantExprs with the nsw, nuw, inbounds,Dan Gohman
and exact flags. Because ConstantExprs are uniqued, creating an expression with this flag causes all expressions with the same operands to have the same flag, which may not be safe. Add, sub, mul, and sdiv ConstantExprs are usually folded anyway, so the main interesting flag here is inbounds, and the constant folder already knows how to set the inbounds flag automatically in most cases, so there isn't an urgent need for the API support. This can be reconsidered in the future, but for now just removing these API bits eliminates a source of potential trouble with little downside. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80959 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Remove the vicmp and vfcmp instructions. Because we never had a release withNick Lewycky
these instructions, no autoupgrade or backwards compatibility support is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74991 91177308-0d34-0410-b5e6-96231b3b80d8
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
2008-08-12Add a NullFolder class that doesn't fold constants.Duncan Sands
This may be used as the second IRBuilder template parameter, the idea being that people learning LLVM may find it helpful (several people asked on IRC if it was possible to turn off constant folding because it made it hard for them to see what was going on). Compiles, but otherwise completely untested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54698 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-12Point people to ConstantExpr and ConstantFolding,Duncan Sands
in case they get the wrong idea. Fit in 80 columns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54676 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11Make it possible to use different constantDuncan Sands
folding policies with IRBuilder. The default, provided by ConstantFolder, is to do minimal folding like now: what ConstantExpr provides. An alternative is to use TargetFolder, which uses target information to fold constants more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54640 91177308-0d34-0410-b5e6-96231b3b80d8
