Evan Cheng cc44b1e743 Can't re-materialize mov r, imm in thumb since mov would clobber the condition code.

Jeff Cohen 68e93b7c44 MS C does have inlining after all, just uses _inline instead of inline.

Jeff Cohen cc560c93eb Fix C Backend to generate code that works with Microsoft C for the benefit of 
front ends that do not depend on the GCC runtime (someday...).

Anton Korobeynikov 7522c9d8e1 Don't allow MatchAddress recurse too much. This trims exponential 
behaviour in some cases.

Chris Lattner bcd38852f2 Compile CodeGen/X86/lea-3.ll:test2 to: 
_test3:
        leaq (,%rdi,4), %rax
        orq %rdi, %rax
        ret

instead of:
_test2:

        orq %rdi, %rax

Chris Lattner c56e4920d2 Fix a problem building llvm-gcc on amd64-unknown-freebsd6.2, due to the 
system assembler not groking legal instructions like "leal (,%esi,8), %ecx".

Bill Wendling ad2db4a4cf Unbreak mmx arithmetic. It was barfing trying to do v8i8 arithmetic.

 2007-03-28 00:57:11 +00:00
Bill Wendling 999c77f89c Add the "unpack low packed data" instructions. This should be the last of 
the MMX instructions that are needed...

comparison operators.

Lauro Ramos Venancio 682baf2dda "The C standards do say that "char" may either be a "signed char" or "unsigned 
char" and it is up to the compilers implementation or the platform which is
followed."

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

Lauro Ramos Venancio a88c4a74f3 bugfix: When the source register of CALL_NOLINK was LR, the following code was emitted: 
mov lr, pc
    bx lr
