Evan Cheng eaf9fba2ff A bit more clean up.

2006-08-26 01:02:19 +00:00
Evan Cheng 548bd0dc95 - Clean up tablegen dag isel generator code.
- Clean up the code generated by tablegen:
  * AddToISelQueue now takes one argument.
  * ComplexPattern matching condition can now be shared.
  * Eliminate passing unnecessary arguments to emit routines.
  * Eliminate some unneeded SDOperand declarations in select routines.
  * Other minor clean ups.
- This reduces foot print slightly: X86ISelDAGToDAG.o is reduced from 971k
  to 823k.

Chris Lattner f4f0b1995c Completely change the way that joining with physregs is implemented. This
paves the way for future changes, increases coallescing opportunities (in
theory, not witnessed in practice), and eliminates the really expensive
LiveIntervals::overlapsAliases method.

Evan Cheng d7572fb234 Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The
asm printer will print it as offset*4. e.g. bne cr0, $+8.

The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.

Reid Spencer 50eac3b8ab For PR797:
Make the Win32 code exception free (untested/uncompiled) which forced some

Reid Spencer 51e6f68b47 For PR797:
Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

Owen Anderson 94446a4267 Revert my previous patch. Since there are some major changes that went in today,
I'm going to wait to put this in HEAD until tomorrow, so as not to clutter the nightly

Chris Lattner bdf121060c Take advantage of the recent improvements to the liveintervals set (tracking
instructions which define each value#) to simplify and improve the coallescer.
In particular, this patch:

1. Implements iterative coallescing.
2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a
   better solution.
3. Implements PR865, "coallescing" away the second copy in code like:

   A = B
   ...
   B = A

This also includes changes to symbolically print registers in intervals
when possible.
