Nick Lewycky f3a07ec394 Switch FnSet to containing the ComparableFunction instead of a pointer to one. 
This reduces malloc traffic (yay!) and removes MergeFunctionsEqualityInfo.

Nick Lewycky 0095937b13 Fix many bugs when merging weak-strong and weak-weak pairs. We now merge all 
strong functions first to make sure they're the canonical definitions and then
do a second pass looking only for weak functions.

 2010-09-05 08:22:49 +00:00
Nick Lewycky 1b36b55f89 No functional change. Replace Out << 'a' << 'b' with Out << "ab" and spell 
David Vandevoorde's name correctly.

Chris Lattner eeba0c73e5 implement rdar://6653118 - fastisel should fold loads where possible. 
Since mem2reg isn't run at -O0, we get a ton of reloads from the stack,
for example, before, this code:

int foo(int x, int y, int z) {
  return x+y+z;
}

used to compile into:

_foo:                                   ## @foo
	subq	$12, %rsp
	movl	%edi, 8(%rsp)
	movl	%esi, 4(%rsp)
	movl	%edx, (%rsp)
	movl	8(%rsp), %edx
	movl	4(%rsp), %esi
	addl	%edx, %esi
	movl	(%rsp), %edx
	addl	%esi, %edx
	movl	%edx, %eax
	addq	$12, %rsp
	ret

Now we produce:

_foo:                                   ## @foo
	subq	$12, %rsp
	movl	%edi, 8(%rsp)
	movl	%esi, 4(%rsp)
	movl	%edx, (%rsp)
	movl	8(%rsp), %edx
	addl	4(%rsp), %edx    ## Folded load
	addl	(%rsp), %edx     ## Folded load
	movl	%edx, %eax
	addq	$12, %rsp
	ret

Fewer instructions and less register use = faster compiles.

Chris Lattner 938cebc076 "const id<NSFoo> *" instead of "id<NSFoo> const *". 
I think this wraps up all the legal cases.

Chris Lattner 53fa04909c make clang print types as "const int *" instead of "int const*", 
which is should have done from the beginning.  As usual, the most
fun with this sort of change is updating all the testcases.

Howard Hinnant 7609c9b665 Changed __config to react to all of clang's currently documented has_feature flags, and renamed _LIBCPP_MOVE to _LIBCPP_HAS_NO_RVALUE_REFERENCES to be more consistent with the rest of the libc++'s flags, and with clang's nomenclature.
