is a mismatch in their character type pointers (i.e. fprintf() prints an

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.

OK, after checking the backwards compatibility code on X86 and the new code
path on alpha, now has come the time for new vararg support. So, with out
further ado, I revert behavior back a couple of years!
Well, ok, I lied. A few more notes.
First, the Simple ISels cannot be expected to work any longer, but they
should still compile
Second, there are likely some bugs to track down once the nightly testers
start with this.
Third, the initial patch doesn't include sparcv9, but I'll do that today.
Forth, subsequent patches won't bother being long winded.
