* Implement review feedback for the ConstantBool->ConstantInt merge. ChrisReid Spencer2007-01-121-2/+2
| | | | | | | | recommended that getBoolValue be replaced with getZExtValue and that get(bool) be replaced by get(const Type*, uint64_t). This implements those changes. llvm-svn: 33110
* For PR1043:Zhou Sheng2007-01-111-3/+3
| | | | | | | Merge ConstantIntegral and ConstantBool into ConstantInt. Remove ConstantIntegral and ConstantBool from LLVM. llvm-svn: 33073
* For PR950:Reid Spencer2006-12-231-10/+20
| | | | | | | | This patch removes the SetCC instructions and replaces them with the ICmp and FCmp instructions. The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. llvm-svn: 32751
* For PR950:Reid Spencer2006-11-271-2/+13
| | | | | | | | | | 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. llvm-svn: 31931
* Remove redundant <cmath>.Jim Laskey2006-11-081-1/+0
| | | | llvm-svn: 31561
* For PR950:Reid Spencer2006-11-081-1/+2
| | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. llvm-svn: 31542
* For PR950:Reid Spencer2006-10-201-7/+7
| | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. llvm-svn: 31063
* Refactor some code to expose an interface to constant fold and instruction ↵Chris Lattner2006-05-271-35/+49

* For PR411:Reid Spencer2006-01-161-5/+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. llvm-svn: 25366

| | | | llvm-svn: 24044
* Move some constant folding code shared by Analysis and Transform passesJohn Criswell2005-10-271-142/+1
| | | | | | | | into the LLVMAnalysis library. This allows LLVMTranform and LLVMTransformUtils to be archives and linked with LLVMAnalysis.a, which provides any missing definitions. llvm-svn: 24036
* Constant fold llvm.sqrtChris Lattner2005-09-281-1/+9

* Fix a fixme in CondPropagate.cpp by moving a PhiNode optimization intoNate Begeman2005-08-041-34/+0
| | | | | | | | BasicBlock's removePredecessor routine. This requires shuffling around the definition and implementation of hasContantValue from Utils.h,cpp into Instructions.h,cpp llvm-svn: 22664

| | | | llvm-svn: 21719
* Remove optimizations that don't require both operands to be constant. TheseReid Spencer2005-04-291-10/+0
| | | | | | are moved to simplify-libcalls pass. llvm-svn: 21614

| | | | | | | | sinh, cosh, etc. * Make the name comparisons for the fp libcalls a little more efficient by switching on the first character of the name before doing comparisons. llvm-svn: 21611
* Remove trailing whitespaceMisha Brukman2005-04-211-11/+11
| | | | llvm-svn: 21427
* Enhance hasConstantValue to ignore undef values in phi nodes. This allows itChris Lattner2004-10-171-2/+3
| | | | | | to think that PHI[4, undef] == 4. llvm-svn: 17096
* Changes For Bug 352Reid Spencer2004-09-011-1/+1
| | | | | | | | Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. llvm-svn: 16137

* Quick hack to get this file compiling again on Mac OS X. The right thing to doBrian Gaeke2004-06-141-0/+8
| | | | | | | | is write an autoconf macro that checks whether __isnan or isnan actually works **using the C++ compiler after #include <cmath>**, instead of doing it the easy way with AC_CHECK_FUNCS(). llvm-svn: 14171
