Jakob Stoklund Olesen 48deb12593 Track defs for all aliases in NEONMoveFix. 
This means that an instruction defining an S register will affect the domain of
the parent D register.

Chris Lattner 6d60a14251 rip out even more sporadic v2f32 support. 
llvm-svn: 107610
 2010-07-05 04:38:33 +00:00
Chris Lattner feb2467bf4 rip out the various v2f32 "mmx" handling logic, now that 
v2f32 is illegal on x86.

llvm-svn: 107609
 2010-07-05 04:36:27 +00:00
Chris Lattner 45cc4d74a3 Just rip v2f32 support completely out of the X86 backend. In 
the example in the testcase, we now generate:

_test1:                                 ## @test1
	movss	4(%esp), %xmm0
	addss	8(%esp), %xmm0
	movl	12(%esp), %eax
	movss	%xmm0, (%eax)
	ret

instead of:

_test1:                                                     ## @test1
	subl	$20, %esp
	movl	24(%esp), %eax
	movq	%mm0, (%esp)
	movq	%mm0, 8(%esp)
	movss	(%esp), %xmm0
	addss	12(%esp), %xmm0
	movss	%xmm0, (%eax)
	addl	$20, %esp
	ret

v2f32 support did not work reliably because most of the X86
backend didn't know it was legal.  It was apparently only added
to support returning source-level v2f32 values in MMX registers
in x86-32 mode.  If ABI compatibility is important on this
GCC-extended-vector type for some reason, then the frontend
should generate IR that returns v2i32 instead of v2f32.  However,
we generally don't try very hard to be abi compatible on gcc
extended vectors.

Chris Lattner 681b926d54 fix PR7518 - terrible codegen of <2 x float>, by only marking 
v2f32 as legal in 32-bit mode.  It is just as terrible there,
but I just care about x86-64 and noone claims it is valuable
in 64-bit mode.

(SDNPMemOperand). This way when they're morphed the memory operands will be

Evan Cheng 0ce84486c3 - Two-address pass should not assume unfolding is always successful. 
- X86 unfolding should check if the instructions being unfolded has memoperands.
  If there is no memoperands, then it must assume conservative alignment. If this
  would introduce an expensive sse unaligned load / store, then unfoldMemoryOperand
  etc. should not unfold the instruction.

Bob Wilson 8a99b730a9 ARM function alignments were off by a power of two. svn 83242 changed 
getFunctionAlignment and the corresponding use of that value in the ARM
asm printer, but now we're using the standard asm printer.  The result of
this was that function alignments were dropped completely for Thumb functions.

Bill Wendling 03bcd6ecc8 Implement the "linker_private_weak" linkage type. This will be used for 
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.

For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

      .globl l_objc_msgSend_fixup_alloc
      .weak_definition l_objc_msgSend_fixup_alloc
      .section __DATA, __objc_msgrefs, coalesced
      .align 3
l_objc_msgSend_fixup_alloc:
       .quad   _objc_msgSend_fixup
       .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Currently only supported on Darwin platforms.
