Enhance the shift-shift folding code to allow a no-op cast to occur in between
...
the shifts.
This allows us to fold this (which is the 'integer add a constant' sequence
from cozmic's scheme compmiler):
int %x(uint %anf-temporary776) {
%anf-temporary777 = shr uint %anf-temporary776, ubyte 1
%anf-temporary800 = cast uint %anf-temporary777 to int
%anf-temporary804 = shl int %anf-temporary800, ubyte 1
%anf-temporary805 = add int %anf-temporary804, -2
%anf-temporary806 = or int %anf-temporary805, 1
ret int %anf-temporary806
}
into this:
int %x(uint %anf-temporary776) {
%anf-temporary776 = cast uint %anf-temporary776 to int
%anf-temporary776.mask1 = add int %anf-temporary776, -2
%anf-temporary805 = or int %anf-temporary776.mask1, 1
ret int %anf-temporary805
}
note that instcombine already knew how to eliminate the AND that the two
shifts fold into. This is tested by InstCombine/shift.ll:test26

submitted method by method. I'll nuke the specialisations and have
the new objects inherit directly from passmanagert, and sanitise the

Added field noResults to Instruction.
...
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

Rewrite FP stackifier support in the X86InstrInfo.td file, splitting patterns
...
that were overloaded to work before and after the stackifier runs. With the
new clean world, it is possible to write patterns for these instructions: woo!
This also adds a few simple patterns here and there, though there are a lot
still missing. These should be easy to add though. :)
See the comments under "Floating Point Stack Support" for more details on
the new world order.
This patch as absolutely no effect on the generated code, woo!

* Added lowering hook for external weak global address. It inserts a load
...
for Darwin.
* Added lowering hook for ISD::RET. It inserts CopyToRegs for the return
value (or store / fld / copy to ST(0) for floating point value). This
eliminate the need to write C++ code to handle RET with variable number
of operands.

Reserve G1 for frame offset stuff and use it to handle large stack frames.
...
For example, instead of emitting this:
test:
save -40112, %o6, %o6 ;; imm too large
add %i6, -40016, %o0 ;; imm too large
call caller
nop
restore %g0, %g0, %g0
retl
nop
emit this:
test:
sethi 4194264, %g1
or %g1, 848, %g1
save %o6, %g1, %o6
sethi 4194264, %g1
add %g1, %i6, %g1
add %i1, 944, %o0
call caller
nop
restore %g0, %g0, %g0
retl
nop
which doesn't cause the assembler to barf.

Fix a nasty latent bug in the legalizer that was triggered by my patch
...
last night, breaking crafty and twolf. Make sure that the newly found
legal nodes are themselves not re-legalized until the next iteration.
Also, since this functionality exists now, we can reduce number of legalizer
iterations by depending on this behavior instead of having to misuse 'do
another iteration' to get the same effect.

Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows
...
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register. This also requires some asm printer work
to satisfy the darwin assembler.
For
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = add <4 x float> %tmp1, %tmp1
store <4 x float> %tmp2, <4 x float> *%a
ret void
}
We now produce:
_foo:
lvx v0, 0, r3
vaddfp v0, v0, v0
stvx v0, 0, r3
blr
Instead of:
_foo:
li r2, 0
lvx v0, r2, r3
vaddfp v0, v0, v0
stvx v0, r2, r3
blr
