Jakob Stoklund Olesen 96fad31694 Teach X86FloatingPoint that a register can be killed multiple times by the same
instruction.

This instruction would crash the pass:

  INLINEASM <es:foo $0 $1>, 9, %FP0<kill>, 9, %FP0<kill>, 14, %EFLAGS<earlyclobber,def,dead>

Now it doesn't.

Evan Cheng 347e3b8f15 Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).

Chris Lattner 6a5e706e3c on darwin empty functions need to codegen into something of non-zero length,
otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

This fixes rdar://7908505

Bill Wendling 11740305f9 Handle a displacement location in 64-bit as an RIP-relative displacement. It
fixes a bug (<rdar://problem/7880900>) in the JIT. This code wouldn't work:

target triple = "x86_64-apple-darwin"

define double @func(double %a) {
  %tmp1 = fmul double %a, 5.000000e-01            ; <double> [#uses=1]
  ret double %tmp1
}

define i32 @main() nounwind {
  %1 = call double @func(double 4.770000e-04) ; <i64> [#uses=0]
  ret i32 0
}

Chris Lattner 84776786a7 teach the x86 address matching stuff to handle
(shl (or x,c), 3) the same as (shl (add x, c), 3)
when x doesn't have any bits from c set.

This finishes off PR1135.  Before we compiled the block to:
to:

LBB0_3:                                 ## %bb
	cmpb	$4, %dl
	sete	%dl
	addb	%dl, %cl
	movb	%cl, %dl
	shlb	$2, %dl
	addb	%r8b, %dl
	shlb	$2, %dl
	movzbl	%dl, %edx
	movl	%esi, (%rdi,%rdx,4)
	leaq	2(%rdx), %r9
	movl	%esi, (%rdi,%r9,4)
	leaq	1(%rdx), %r9
	movl	%esi, (%rdi,%r9,4)
	addq	$3, %rdx
	movl	%esi, (%rdi,%rdx,4)
	incb	%r8b
	decb	%al
	movb	%r8b, %dl
	jne	LBB0_1

Now we produce:

LBB0_3:                                 ## %bb
	cmpb	$4, %dl
	sete	%dl
	addb	%dl, %cl
	movb	%cl, %dl
	shlb	$2, %dl
	addb	%r8b, %dl
	shlb	$2, %dl
	movzbl	%dl, %edx
	movl	%esi, (%rdi,%rdx,4)
	movl	%esi, 8(%rdi,%rdx,4)
	movl	%esi, 4(%rdi,%rdx,4)
	movl	%esi, 12(%rdi,%rdx,4)
	incb	%r8b
	decb	%al
	movb	%r8b, %dl
	jne	LBB0_1

Dale Johannesen 0522b90cdb Because of the EMMS problem, right now we have to support
user-defined operations that use MMX register types, but
the compiler shouldn't generate them on its own.  This adds
a Synthesizable abstraction to represent this, and changes
the vector widening computation so it won't produce MMX types.
(The motivation is to remove noise from the ABI compatibility
part of the gcc test suite, which has some breakage right now.)

value, which is now mapped to ARMCC::AL.
