c9903eb2cc I really didn't think this was necessary. But, Legalize wasn't running again 
and legalizing the extload.  Strange.  Should fix most alpha regressions.

6a865d5a22 Varargs is apparently currently broken on PPC. This hacks it so that it 
is at least overloading the right virtual methods.  The implementations
are currently wrong though.  This fixes Ptrdist/bc, but not other programs
(e.g. siod).

02fe175f3d Fix PR590 and Transforms/Mem2Reg/2005-06-30-ReadBeforeWrite.ll. 
The optimization for locally used allocas was not safe for allocas that
were read before they were written.  This change disables that optimization
in that case.

31e3028bac Make the x86 asm printer darwin-aware. This mostly entails doing the same 
thing as cygwin most of the time, and printing our alignments in log2
rather than number of bytes.

1bafe064da Basic fix for PR#591; don't convert an fprintf() to an fwrite() if there 
is a mismatch in their character type pointers (i.e. fprintf() prints an
array of ubytes while fwrite() takes an array of sbytes).
We can probably do better than this (such as casting the ubyte to an
sbyte).

41d08a0bbe Get rid of all symbolic loads. I now do gernate all relocations sequences 
rather than relying on the assembler.  Only a few more pseudo instructions
left.  Also merge load code paths.

cc12cd8c5a So, it turns out I forgot that one valid way of restoring GP after a call 
is to use RA, which assumes the called function uses RA for the register
holding the return address when it issues a ret.

032a94775d Initial set of .td file changes necessary to get scalar fp in xmm registers 
working.  The instruction selector changes will hopefully be coming later
this week once they are debugged.  This is necessary to support the darwin
x86 FP model, and is recommended by intel as the replacement for x87.  As
a bonus, the register allocator knows how to deal with these registers
across basic blocks, unliky the FP stackifier.  This leads to significantly
better codegen in several cases.

cd6b5c5011 Add support to the X86 backend for emitting ELF files. To use this, we 
currently use: llc t.bc --filetype=obj

This will produce a t.o file which is dumpable with readelf.  Currently
the file produced is empty, but the scaffolding to do more is now in place.

a section table and a section table string table.  This will be enhanced
