Brian Gaeke 04cff21c2f Cygwin defines log2 as a macro. Undef it here IFF it has already been defined, 
so that we always get the inline function instead. Remember, kids, like it says
in the GCC manual, "An Inline Function is As Fast As a Macro."

Brian Gaeke 01d9231855 small portability fix.

Chris Lattner 396cdaf067 Add support for remove, fwrite, and fread 
Also fix problem where we didn't check to see if a node pointer was null.
Though fclose(null) doesn't make a lot of sense, 300.twolf does it.

Chris Lattner b471f0188f Fix some unexpected fallout from the config.h changes. Because the CBE no 
longer was getting this #include, it always fell back on the less precise
floating point initializer values, causing some testsuite failures.

Alkis Evlogimenos 1dd872ce94 Move machine code rewriter and spiller outside the register 
allocator.

The implementation is completely rewritten and now employs several
optimizations not exercised before. For example for 164.gzip we have
997 loads and 699 stores vs the 1221 loads and 880 stores we have
before.

Chris Lattner a2ab489135 Implement SimplifyCFG/switch_switch_fold.ll 
This case occurs many times in various benchmarks, especially when combined
with the previous patch.  This allows it to get stuff like:
  if (X == 4 || X == 3)
    if (X == 5 || X == 8)

and

switch (X) {
case 4: case 5: case 6:
  if (X == 4 || X == 5)

llvm-svn: 11797
 2004-02-24 07:23:58 +00:00
Chris Lattner fe7a92fe7c New testcase. Switch instructions that go to switch instructions should be 
merged.

llvm-svn: 11796
 2004-02-24 07:21:09 +00:00
Alkis Evlogimenos 63aea0b6a5 Add predicates for checking if a virtual register has a physical 
register mapping or a stack slot mapping.

 2004-02-24 05:54:22 +00:00
Chris Lattner 6f4b45acf5 Implement: test/Regression/Transforms/SimplifyCFG/switch_create.ll 
This turns code like this:
  if (X == 4 | X == 7)
and
  if (X != 4 & X != 7)
into switch instructions.

llvm-svn: 11792
 2004-02-24 05:38:11 +00:00
Chris Lattner ae509325d6 The simplifycfg pass should be able to turn stuff like: 
if (X == 4 || X == 7)
and
  if (X != 4 && X != 7)

into switch instructions.

Chris Lattner cf96c6caa5 Wow, the description of the 'switch' instruction was out of date.

Chris Lattner 101e704b0b Use the new LLVM is_class template instead of the boost one, allowing us to 
remove our dependency on boost!  Thanks to Reid Spencer for making this possible!

llvm-svn: 11785
 2004-02-24 03:50:05 +00:00
Chris Lattner 78eed17a29 Check in a new type_traits header which provides the mysterious is_class 
template.  Thanks go out to Reid Spencer for skillfully extracting this
from boost!
