Sameer D. Sahasrabuddhe for pointing this out!

1d231ec0b0 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).

c7989cef9d 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.

f4b3278aeb 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.

6968bff783 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.

f1702ac589 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.

07a9144efe 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.

in the future :)
