Currently we're initializing the vtable pointers of a class only after
...
the bases are completely initialized. This won't work --- base
initializer expressions can rely on the vtables having been set up.
Check for uses of 'this' in the initializers and force a vtable
initialization if found.
This might not be good enough; we might need to extend this to handle
the possibility of arbitrary code finding an external reference to this
(not yet completely-constructed!) object and accessing through it,
in which case we'll probably find ourselves doing a lot more unnecessary
stores.

When emitting a new-expression inside a conditional expression,
...
the cleanup might not be dominated by the allocation code.
In this case, we have to store aside all the delete arguments
in case we need them later. There's room for optimization here
in cases where we end up not actually needing the cleanup in
different branches (or being able to pop it after the
initialization code).
Also make sure we only call this operator delete along the path
where we actually allocated something.

Implement C++0x user-defined string literals.
...
The extra data stored on user-defined literal Tokens is stored in extra
allocated memory, which is managed by the PreprocessorLexer because there isn't
a better place to put it that makes sure it gets deallocated, but only after
it's used up. My testing has shown no significant slowdown as a result, but
independent testing would be appreciated.

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
There is still "stuff to be done" here for the struct case,

fix rdar://8340348, a miscompile of boost that was exposed by r109848.
...
That revision started classifying truly empty structs like "Y" and "X"
as being NoClass/NoClass and turning them into 'ignore'. The call code
turns around and allocates space for the ignored argument with
GetUndefRValue. The bug is that GetUndefRValue would return the address
as undef, instead of returning an object with a defined address but
undefined contents.

When performing value-initialization for a class with a non-trivial,

Also, simplify the hideous logic that determines when we have a
trivial default constructor and, therefore, don't need to emit any
call at all.
