b3518a838c Fix a thinko. If the operand is promoted, pass the promoted value into
the new zero extend, not the original operand.  This fixes cast bool -> long
on ppc.

Add an unrelated fixme

c1bacbff9d 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!

17c60891c1 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.

ed826ae12c new testcase that used to crash the ppc fe. It could effect any simpleisel
that is not careful, so I'm checking it into the generic tests.

034716de24 add a little peephole optimization. This allows us to codegen:
int a(short i) {
        return i & 1;
}

as

_a:
        andi. r3, r3, 1
        blr

instead of:

_a:
        rlwinm r2, r3, 0, 16, 31
        andi. r3, r2, 1
        blr

on ppc.  It should also help the other risc targets.

2d3e52576d 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.

98bcb13bfa 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:

        fneg f0, f1
        fneg f0, f0

afa0001d54 recognize some patterns as fabs operations, so that fabs at the source level
is deconstructed then reconstructed here.  This catches 19 fabs's in 177.mesa
9 in 168.wupwise, 5 in 171.swim, 3 in 172.mgrid, and 14 in 173.applu out of
specfp2000.

This allows the X86 code generator to make MUCH better code than before for
each of these and saves one instr on ppc.

This depends on the previous CFE patch to expose these correctly.

9a56ef5693 If a target zero or sign extends the result of its setcc, allow folding of
this into sign/zero extension instructions later.

On PPC, for example, this testcase:

%G = external global sbyte
implementation
void %test(int %X, int %Y) {
  %C = setlt int %X, %Y
  %D = cast bool %C to sbyte
  store sbyte %D, sbyte* %G
  ret void
}

Now codegens to:

        cmpw cr0, r3, r4
        li r3, 1
        li r4, 0
        blt .LBB_test_2 ;
.LBB_test_1:    ;
        or r3, r4, r4
.LBB_test_2:    ;
        addis r2, r2, ha16(L_G$non_lazy_ptr-"L00000$pb")
        lwz r2, lo16(L_G$non_lazy_ptr-"L00000$pb")(r2)
        stb r3, 0(r2)

instead of:

        cmpw cr0, r3, r4
        li r3, 1
        li r4, 0
        blt .LBB_test_2 ;
.LBB_test_1:    ;
        or r3, r4, r4
.LBB_test_2:    ;
***     rlwinm r3, r3, 0, 31, 31
        addis r2, r2, ha16(L_G$non_lazy_ptr-"L00000$pb")
