Bill Wendling e9b81f5366 Adding more arithmetic operators to MMX. This is an almost exact copy of
the addition. Please let me know if you have suggestions.

Bill Wendling 6092ce25cf Added "padd*" support for MMX. Added MMX move stuff to X86InstrInfo so that
moves, loads, etc. are recognized.

Chris Lattner 9c7e5e365d argument lowering should copy from the vreg shadows of live-in arguments
passed in registers, not directly from the pregs themselves.

Chris Lattner 294780829a initial hack at splitting the x86-64 calling convention info out from the
mechanics that process it.  I'm still not happy with this, but it's a step
in the right direction.

Chris Lattner 1db979bae8 in X86-64 CCC, i8/i16 arguments are already properly zext/sext'd on input.
Capture this so that downstream zext/sext's are optimized out.  This
compiles:
  int test(short X) { return (int)X; }

to:

_test:
        movl %edi, %eax
        ret

instead of:

_test:
        movswl %di, %eax
        ret


GCC produces this bizarre code:

_test:
        movw    %di, -12(%rsp)
        movswl  -12(%rsp),%eax
        ret

Chris Lattner 8924332e22 Fix an X86-64 abi bug. We now compile:
void foo(short);
void bar(unsigned short A) {
  foo(A);
}

into:

_bar:
        subq $8, %rsp
        movswl %di, %edi
        call _foo
        addq $8, %rsp
        ret

instead of:

_bar:
        subq $8, %rsp
        call _foo
        addq $8, %rsp
        ret

Chris Lattner 3e0703357f fix CodeGen/X86/2007-02-25-FastCCStack.ll, a regression from my patch last
night:  fastcc returns should only go in XMM0 if we have SSE2 or above.

llvm-svn: 34613
2007-02-25 22:23:46 +00:00
Chris Lattner fcee9b5568 fastcc functions that return double values now return them in xmm0 on x86-32.
This implements CodeGen/X86/fp-stack-ret.ll:test[23]

Chris Lattner 2fc0d70392 move LowerRET into the 'Return Value Calling Convention Implementation'
section of the file.

llvm-svn: 34589
2007-02-25 09:12:39 +00:00
Chris Lattner ba474f58a4 make all Lower*CallTo implementations use LowerCallResult to handle their
result value stuff.  This eliminates a bunch of duplicated code and now
GetRetValueLocs is the sole place that decides where a value is returned.

llvm-svn: 34588
2007-02-25 09:10:05 +00:00
Chris Lattner 7802f3e2ea pass the calling convention into Lower*CallTo, instead of using ad-hoc flags.
llvm-svn: 34587
2007-02-25 09:06:15 +00:00
Chris Lattner 0cd9960fe7 factor a bunch of code out of LowerCCCCallTo into a new LowerCallResult
function.  This function now uses GetRetValueLocs to determine *where*
the result values are located and concerns itself with *how* to pull the
values out.

Chris Lattner 3c76309a5b move some code around, pass in calling conv, even though it is unused
llvm-svn: 34585
2007-02-25 08:29:00 +00:00
Chris Lattner dfda38f7dc simplify result value lowering by splitting the selection of *where* to return
registers out from the logic of *how* to return them.

This changes X86-64 to mark EAX live out when returning a 32-bit value,
where before it marked RAX liveout.

Evan Cheng 84a041eb98 ELF / PIC requires GOT be in the EBX register during calls via PLT GOT pointer.
Add implicit uses of EBX to calls to ensure liveintervalanalysis does not treat
the GOT in EBX move as dead upon definition.
This should fix PR1207.
