c1d3d10249 support functions that return bool (this "should" work but doesn't,
*maybe* due to a legalizer bug.)

2b4ea795a2 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.

171049d10f * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.

  lowered so it does not have a flag operand.)

64aa0ea4e9 this is a hack, which may or may not hang around. In short:
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?

98d1378343 I shoulda done this a *long* time ago (tm): implement calls properly,
i.e. r1/r12/rp are saved/restored regardless of scheduling/luck

TODO: calls to external symbols, indirect (function descriptor) calls,
      performance (we're being paranoid right now)

BUG: the code for handling calls to vararg functions breaks if FP
args are passed (this will make printf() go haywire so a bunch of
tests will fail)

BUG: this seems to trigger some legalize nastiness

58fe459e36 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!

85e42b45ac 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.
