Chris Lattner b055c8737f Work around a nasty tblgen bug where it doesn't add operands for varargs 
nodes correctly.

Chris Lattner 006b2c6ab9 Fix a problem exposed by the local allocator. CALL instructions are not marked 
as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.

Evan Cheng dc614c193e Added X86FunctionInfo subclass of MachineFunction to record whether the 
function that is being lowered is forced to use FP. Currently this is only
true for main() / Cygwin.

Chris Lattner 16826c3503 Now that PR633 is implemented, the CBE can know to emit _setjmp/_longjmp 
when available.  This speeds up hexxagon from 18.61s to 16.61s with the CBE on
PPC Mac OS (for reference, LLC is 15.48s and GCC is 23.35s).

Reid Spencer 75f29be136 For PR786: 
Don't warn about -pedantic errors. Add a note to the PR instead.

llvm-svn: 28616
 2006-06-01 05:49:51 +00:00
Reid Spencer a62f097c96 For PR786: 
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.

llvm-svn: 28614
 2006-06-01 01:55:21 +00:00
Reid Spencer a647c7ff42 Use archive libraries instead of object files for VMCore, BCReader, 
BCWriter, and bzip2 libraries. Adjust the various makefiles to accommodate
these changes. This was done to speed up link times.

Evan Cheng f21045a5cd Somehow I lost a condition when I was shuffling some code around. Anyway, 
only transform a shufps to pshufd when the first two operands are the same.

llvm-svn: 28572
 2006-05-30 21:29:15 +00:00
Chris Lattner b9342afa56 Always reserve space for 8 spilled GPRs. GCC apparently assumes that this 
space will be available, even if the callee isn't varargs.

 2006-05-30 07:37:37 +00:00
Evan Cheng 734e1e241b A addressing mode folding enhancement: 
Fold c2 in (x << c1) | c2 where (c2 < c1)
e.g.
int test(int x) {
  return (x << 3) + 7;
}

This can be codegen'd as:
leal 7(,%eax,8), %eax

vector arguments, not three.
