John McCall 6bde954f47 Extract procedures to do scalar-to-memory and memory-to-scalar conversions

intrinsics.  rdar://problem/8461234

John McCall 5fe84129e2 A couple of tweaks to the visibility rules:
- tags with C linkage should ignore visibility=hidden
  - functions and variables with explicit visibility attributes should
    ignore the linkage of their types
Either of these should be sufficient to fix PR8457.

Also, FileCheck-ize a test case.

Douglas Gregor 559c9fb134 This patch fixes multiple issues in clang's designated init builder and
completes support for C1X anonymous struct/union init features:

 * Indexed anonymous member initializers should not be expanded. Doing so makes
little sense and would cause unresolvable semantic ambiguity in valid code
(regression introduced by r69153).

 * Subobject initialization of (possibly nested) anonymous members are now
referred to with paths relative to the naming record context, eliminating the
synthesis of incorrect implicit InitListExprs that caused CodeGen to assert.

 * Field lookup was missing a null check in IdentifierInfo comparison which
caused lookup for a known (already resolved) field to match the first unnamed
data member it encountered leading to silent miscompilation.

 * Subobject paths are no longer built using the general purpose
Sema::BuildAnonymousStructUnionMemberPath(). If any corner cases crop up, we
will now assert earlier in Sema instead of passing invalid InitListExprs
through to CodeGen.

Fixes PR6955, from Alp Toker!

llvm-svn: 114376
2010-09-20 23:50:22 +00:00
Fariborz Jahanian 2b1d88abfb Problem with gnu conditional extension with missing
LHS and when conditional expression is an array. Since
it will be decayed, saved expression must be saved with
decayed expression. This is necessary to preserve semantics
of this extension (and prevent an IRGen crash which expects
an array to always be decayed). I am sure there will be other
cases in c++ (aggregate conditionals for example) when saving of the 
expression must happen after some transformation on conditional
expression has happened. 
Doug, please review.  Fixes // rdar://8446940

llvm-svn: 112112
2010-08-25 23:42:51 +00:00
Chris Lattner 9f8b451876 Finally pass "two floats in a 64-bit unit" as a <2 x float> instead of
as a double in the x86-64 ABI.  This allows us to generate much better
code for certain things, e.g.:

_Complex float f32(_Complex float A, _Complex float B) {
  return A+B;
}

Used to compile into (look at the integer silliness!):

_f32:                                   ## @f32
## BB#0:                                ## %entry
	movd	%xmm1, %rax
	movd	%eax, %xmm1
	movd	%xmm0, %rcx
	movd	%ecx, %xmm0
	addss	%xmm1, %xmm0
	movd	%xmm0, %edx
	shrq	$32, %rax
	movd	%eax, %xmm0
	shrq	$32, %rcx
	movd	%ecx, %xmm1
	addss	%xmm0, %xmm1
	movd	%xmm1, %eax
	shlq	$32, %rax
	addq	%rdx, %rax
	movd	%rax, %xmm0
	ret

Now we get:

_f32:                                   ## @f32
	movdqa	%xmm0, %xmm2
	addss	%xmm1, %xmm2
	pshufd	$16, %xmm2, %xmm2
	pshufd	$1, %xmm1, %xmm1
	pshufd	$1, %xmm0, %xmm0
	addss	%xmm1, %xmm0
	pshufd	$16, %xmm0, %xmm1
	movdqa	%xmm2, %xmm0
	unpcklps	%xmm1, %xmm0
	ret

and compile stuff like:

extern float _Complex ccoshf( float _Complex ) ;
float _Complex ccosf ( float _Complex z ) {
 float _Complex iz;
 (__real__ iz) = -(__imag__ z);
 (__imag__ iz) = (__real__ z);
 return ccoshf(iz);
}

into:

_ccosf:                                 ## @ccosf
## BB#0:                                ## %entry
	pshufd	$1, %xmm0, %xmm1
	xorps	LCPI4_0(%rip), %xmm1
	unpcklps	%xmm0, %xmm1
	movaps	%xmm1, %xmm0
	jmp	_ccoshf                 ## TAILCALL

instead of:

_ccosf:                                 ## @ccosf
## BB#0:                                ## %entry
	movd	%xmm0, %rax
	movq	%rax, %rcx
	shlq	$32, %rcx
	shrq	$32, %rax
	xorl	$-2147483648, %eax      ## imm = 0xFFFFFFFF80000000
	addq	%rcx, %rax
	movd	%rax, %xmm0
	jmp	_ccoshf                 ## TAILCALL

Chris Lattner 9052c35479 fix some vector extractions to return properly zero extended values
(instead of sign extending) to match ICC.  GCC is changing this in 
a series of their own PRs (e.g. 41323).
