* 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
* Eliminate all remaining tabs and trailing spaces.Jeff Cohen2005-07-271-3/+3
| | | | llvm-svn: 22523
* prevent DCE of vaarg intrinsics. This should take care of most regressionsAndrew Lenharth2005-06-191-2/+0
| | | | llvm-svn: 22263
* DCE intrinsic instructions without side effects.Chris Lattner2005-05-061-1/+20
| | | | 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
* * Add constant folding for additional floating point library calls such asReid Spencer2005-04-281-26/+90
| | | | | | | | 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
* Use new IsNAN() wrapper.Brian Gaeke2004-06-231-15/+2
| | | | llvm-svn: 14340
* Comment out the isnan stuff until we get a proper autoconf test for itChris Lattner2004-06-211-1/+7
| | | | | | breaking the build on sparc is not acceptable. llvm-svn: 14277
* I love the smell of a freshly broken PowerPC build in the morning.Brian Gaeke2004-06-171-0/+1
| | | | llvm-svn: 14206
* Fix compilation problem on freebsd. Problem noted by Vladimir Merzliakov inChris Lattner2004-06-171-1/+1
| | | | | | PR371 llvm-svn: 14203
* Um, did someone make a typo or something?Brian Gaeke2004-06-151-1/+1
| | | | llvm-svn: 14192
* Remove support for the isnan intrinsicChris Lattner2004-06-151-3/+0
| | | | llvm-svn: 14186
* 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
* Add constant folding capabilities to the isunordered intrinsic.Alkis Evlogimenos2004-06-131-1/+4
| | | | llvm-svn: 14168
* Constant fold the isnan intrinsicChris Lattner2004-06-111-1/+10
| | | | llvm-svn: 14150
* Implement constant folding of fmod, which is used a lot in povrayChris Lattner2004-05-271-2/+9
| | | | llvm-svn: 13823
* Restructure call constant folding code a bit to make it simplerChris Lattner2004-05-271-39/+40
| | | | | | | | Add support for acos/asin/atan. 188.ammp contains three calls to acos with constant arguments. Constant folding it allows elimination of those 3 calls and three FP divisions of the results. llvm-svn: 13821
* Include cerrno (gcc-3.4 fix)Alkis Evlogimenos2004-04-211-0/+1
