Chris Lattner 9ff4b4190f rename getPPCOpcodeForSetCCNumber -> getPPCOpcodeForSetCCOpode to be more 
correct.  Remove the EmitComparison retvalue, as it is always the first arg.

Fix a place where we incorrectly passed in the setcc opcode instead of the
setcc number, causing us to miscompile crafty.  Crafty now works!

Chris Lattner 228fed92e6 Fix CodeGen/Generic/2005-05-09-GlobalInPHI.ll, which was reduced from 254.gap. 
This caused the "use before a def" assertion on some programs.

With this patch, 254.gap now passes with the PPC backend.

Duraid Madina 46aa06cfed ok, the "ia64 has a boatload of registers" joke stopped being funny today ;) 
* fix overallocation of integer (stacked) registers: we can't allocate
  registers for local use if they are required as output registers

this fixes 'toast' in the test suite, and all sorts of larger programs
like bzip2 etc.

Nate Begeman 2f64122319 Optimize FSEL a bit for fneg arguments. This fixes the recently added test 
case so that we emit

_test_fneg_sel:
.LBB_test_fneg_sel_0:   ;
        fsel f1, f1, f3, f2
        blr

instead of:

_test_fneg_sel:
.LBB_test_fneg_sel_0:   ;
        fneg f0, f1
        fneg f0, f0
        fsel f1, f0, f3, f2

Nate Begeman 9049e4beec Rename canUseAsImmediateForOpcode to getImmediateForOpcode to better

that regalloc doesn't cleverly reuse early arg regs loading later arg regs.

  * Start to handle function descriptors: compute target GPs and so on
  when doing indirect calls etc. Not there yet, though. For the moment,
  we try to use _indirect_ branches wherever possible, to stress test
  function descriptors.
  * FP divide-by-zero should work now
  * add varargs (it doesn't work, though)

At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)

  volatile store int** %P, int*** %Q

  l1_P = *l2_Q;
  *((volatile int ***)l2_Q) = l1_P;

... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):

  int *l3_A;

  l3_A = *((int * volatile*)l1_P);
  return;
}
void test2(int ***l2_Q) {

Andrew Lenharth e0b789fdf5 so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
