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

158f6092a2 Promote to v1i64 type... 
llvm-svn: 35353
 2007-03-26 08:03:33 +00:00

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
