it is defined in.

Anton Korobeynikov 8b7aab009e Implemented correct stack probing on mingw/cygwin for dynamic alloca's. 
Also, fixed static case in presence of eax livin. This fixes PR331

PS: Why don't we still have push/pop instructions? :)

Jeff Cohen da17029218 Before assuming that the original code didn't work for Athlon64, the person who 
replaced it with a FIXME should have determined what did work.  Then he would have
realized that the code was in fact correct, and would have avoided breaking it.

Chris Lattner 7451e4d6a1 move a bunch of register constraints from being handled by 
getRegClassForInlineAsmConstraint to being handled by
getRegForInlineAsmConstraint.  This allows us to let the llvm register allocator
allocate, which gives us better code.  For example, X86/2007-01-29-InlineAsm-ir.ll
used to compile to:

_run_init_process:
        subl $4, %esp
        movl %ebx, (%esp)
        xorl %ebx, %ebx
        movl $11, %eax
        movl %ebx, %ecx
        movl %ebx, %edx
        # InlineAsm Start
        push %ebx ; movl %ebx,%ebx ; int $0x80 ; pop %ebx
        # InlineAsm End

Now we get:
_run_init_process:
        xorl %ecx, %ecx
        movl $11, %eax
        movl %ecx, %edx
        # InlineAsm Start
        push %ebx ; movl %ecx,%ebx ; int $0x80 ; pop %ebx
        # InlineAsm End

Bill Wendling 48a24419bf Updated. 
llvm-svn: 35352
 2007-03-26 07:55:58 +00:00
Bill Wendling 98d2104c6f Add support for the v1i64 type. This makes better code for this: 
#include <mmintrin.h>

extern __m64 C;

void baz(__v2si *A, __v2si *B)
{
  *A = C;
  _mm_empty();
}

We get this:

_baz:
        call "L1$pb"
"L1$pb":
        popl %eax
        movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
        movq (%eax), %mm0
        movl 4(%esp), %eax
        movq %mm0, (%eax)
        emms
        ret

GCC gives us this:

_baz:
        pushl   %ebx
        call    L3
"L00000000001$pb":
L3:
        popl    %ebx
        subl    $8, %esp
        movl    L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
        movl    (%eax), %edx
        movl    4(%eax), %ecx
        movl    16(%esp), %eax
        movl    %edx, (%eax)
        movl    %ecx, 4(%eax)
        emms
        addl    $8, %esp
        popl    %ebx
        ret
