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.

a2f68cf0f9 When compiled with GCC 4.0, a latent bug was exposed where both SparcV9
and the target independant register allocator were both using a class named

SparcV9 backend, which crashed.  Fixed by renaming SparcV9's LiveRange to

47cd13d42a Handle some more real world cases of rlwimi. These don't come up that
regularly in "normal" code, but for things like software graphics, they
make a big difference.

For the following code:
unsigned short Trans16Bit(unsigned srcA,unsigned srcB,unsigned alpha)
{
	unsigned tmpA,tmpB,mixed;
	tmpA = ((srcA & 0x03E0) << 15) | (srcA & 0x7C1F);
	tmpB = ((srcB & 0x03E0) << 15) | (srcB & 0x7C1F);
	mixed = (tmpA * alpha) + (tmpB * (32 - alpha));
	return ((mixed >> 5) & 0x7C1F) | ((mixed >> 20) & 0x03E0);
}

We now generate:
_Trans16Bit:
.LBB_Trans16Bit_0:      ; entry
        andi. r2, r4, 31775
        rlwimi r2, r4, 15, 7, 11
        subfic r4, r5, 32
        mullw r2, r2, r4
        andi. r4, r3, 31775
        rlwimi r4, r3, 15, 7, 11
        mullw r3, r4, r5

        andi. r3, r3, 31775
        rlwimi r3, r2, 12, 22, 26
        blr

Instead of:
_Trans16Bit:
.LBB_Trans16Bit_0:      ; entry
        slwi r2, r4, 15
        rlwinm r2, r2, 0, 7, 11

4062a79a81 Fix 2005-05-12-Int64ToFP
The issue is there is no unsigned -> double conversion, only signed.  So I
need to test the sign and do a different thing depending on it.  Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.

adde8b1a71 Use target-specific nodes for calls. This allows the fastcc code to not have
to do ugly hackery to avoid emitting code like this:

   call foo
   mov vreg, EAX
   adjcallstackup ...

If foo is a fastcc call and if vreg gets spilled, we might end up with this:

   call foo
   mov [ESP+offset], EAX     ;; Offset doesn't consider the 12!
   sub ESP, 12

Which is bad.  The previous hacky code to deal with this was A) gross B) not
good enough.  In particular, it could miss cases and emit the bad code above.
Now we always emit this:

   call foo
   adjcallstackup ...
   mov vreg, EAX

directly.

This makes fastcc with callees poping the stack work much better.  Next
stop (finally!) really is tail calls.
