* Change constant folding APIs to take an optional TargetData, and changeChris Lattner2007-01-30
| | | | | | | | | | | | ConstantFoldInstOperands/ConstantFoldCall to take a pointer to an array of operands + size, instead of an std::vector. In some cases, switch to using a SmallVector instead of a vector. This allows us to get rid of some special case gross code that was there to avoid the cost of constructing a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33670 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement review feedback for the ConstantBool->ConstantInt merge. ChrisReid Spencer2007-01-12

The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32751 91177308-0d34-0410-b5e6-96231b3b80d8
* For PR950:Reid Spencer2006-11-27
| | | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR411:Reid Spencer2006-01-16
| | | | | | | | | | | | | | | | | This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25366 91177308-0d34-0410-b5e6-96231b3b80d8
