Enhance hasConstantValue to ignore undef values in phi nodes. This allows it
to think that PHI[4, undef] == 4.

Changes For Bug 352
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/l

Comment out the isnan stuff until we get a proper autoconf test for it
breaking the build on sparc is not acceptable.

I love the smell of a freshly broken PowerPC build in the morning.

Fix compilation problem on freebsd. Problem noted by Vladimir Merzliakov in
PR371

llvm-svn: 14203

Um, did someone make a typo or something?

llvm-svn: 14192

Remove support for the isnan intrinsic

llvm-svn: 14186

Quick hack to get this file compiling again on Mac OS X. The right thing to do
is write an autoconf macro that checks whether __isnan or isnan actually works
**using the C++ compiler after #include

Quick hack to get this file compiling again on Mac OS X. The right thing to do
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().

Add constant folding capabilities to the isunordered intrinsic.

Constant fold the isnan intrinsic

llvm-svn: 14150

Implement constant folding of fmod, which is used a lot in povray

llvm-svn: 13823

Restructure call constant folding code a bit to make it simpler
Add support for acos/asin/atan. 188.ammp contains three calls to acos with
constant arguments. Constant folding it allows elimination

Restructure call constant folding code a bit to make it simpler
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.
