Chris Lattner d313b92b66 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).

Chris Lattner 937c71f2b3 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.

Nate Begeman 718387e491 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.

John Criswell 4642afdcc1 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).

Andrew Lenharth 1ef3c0c798 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.

Andrew Lenharth d74877a46d Adapt the code for handling uint -> fp conversion for the 32 bit case to 
handling it in the 64 bit case.  The two code paths should probably be merged.

Andrew Lenharth a50adcf57d 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.

Nate Begeman db32921535 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.

Chris Lattner 10594206f4 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.

Chris Lattner 386b151ce6 iniital checkin of ELFWriter implementation

a section table and a section table string table.  This will be enhanced
in the future :)

Andrew Lenharth 331380b2e2 With setOperationAction(ISD::UINT_TO_FP, MVT::i64, Expand), Legalize
