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

llvm-svn: 34838

Chris Lattner dc3adc83e7 move CC Lowering stuff to its own public interface 
llvm-svn: 34655
 2007-02-27 04:43:02 +00:00
Chris Lattner 2e5e8407ad refactor x86-64 argument lowering yet again, this time eliminating templates, 
'clients', etc, and adding CCValAssign instead.

llvm-svn: 34654
 2007-02-27 04:18:15 +00:00
Chris Lattner ff19957468 switch to smallvector 
llvm-svn: 34633
 2007-02-26 07:59:53 +00:00
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.

llvm-svn: 34631
 2007-02-26 07:50:02 +00:00
Chris Lattner d41bff0f97 the truncate must always be done, it's only the assert that is conditional.

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

llvm-svn: 34623
 2007-02-26 03:18:56 +00:00
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

Testcase here: test/CodeGen/X86/x86-64-shortint.ll

 2007-02-25 23:10:46 +00:00
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]

llvm-svn: 34592
 2007-02-25 09:31:16 +00:00
Chris Lattner 9d9cc84f5b allow vectors to be passed to stdcall/fastcall functions 
llvm-svn: 34590
 2007-02-25 09:14:25 +00:00
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.

llvm-svn: 34586
 2007-02-25 08:59:22 +00:00
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.

llvm-svn: 34582
 2007-02-25 08:15:11 +00:00

Chris Lattner e56fef9b51 eliminate temporary vectors created during X86 lowering. 
llvm-svn: 34577
