Evan Cheng 9dbe99dcd6 A number of LSR fixes: 
- ChangeCompareStride only reuse stride that is larger than current stride. It
  will let the general reuse mechanism to try to reuse a smaller stride.
- Watch out for multiplication overflow in ChangeCompareStride.
- Replace std::set with SmallPtrSet.

Steve Naroff 161a92b976 Start rewriting ObjC interfaces. As a start, we comment out all the methods. This involved refining how the parser/AST passes/manages SourceLocations for ObjcMethodDecl's.

Fariborz Jahanian 3339d0d14e This patch allows synthesis generation of ivar offset for legacy objective-c @implementation 
decl without an @interface decl.

Bill Wendling b0bfd69684 On second thought. Remove this as it should never be generated in the first 
place.

Bill Wendling 6d15b32c15 - Remove the hacky code that forces a memcpy. Alignment is taken care of in the 
FE.
- Explicitly pass in the alignment of the load & store.
- XFAIL 2007-10-23-UnalignedMemcpy.ll because llc has a bug that crashes on
  unaligned pointers.

Ted Kremenek 16c7d8ce5b Added skeleton implementation of serialization for types (not complete).

 2007-10-26 20:24:35 +00:00
Ted Kremenek fc88b1ddb8 Added default implementation of SerializeTrait<> that dispatches to 
calling member functions of the target type to perform type-specific
serialization.
                         
Added version of ReadPtr that allows passing references to uintptr_t
(useful for smart pointers).

Anton Korobeynikov d07d6a411c Fix off-by-one stack offset computations (dwarf information) for callee-saved 
registers in case, when FP pointer was eliminated. This should fixes misc. random
EH-related crahses, when stuff is compiled with -fomit-frame-pointer.
Thanks Duncan for nailing this bug!

Evan Cheng 7f3d02471d Loosen up iv reuse to allow reuse of the same stride but a larger type when truncating from the larger type to smaller type is free. 
e.g.
Turns this loop:
LBB1_1: # entry.bb_crit_edge
        xorl    %ecx, %ecx
        xorw    %dx, %dx
        movw    %dx, %si
LBB1_2: # bb
        movl    L_X$non_lazy_ptr, %edi
        movw    %si, (%edi)
        movl    L_Y$non_lazy_ptr, %edi
        movw    %dx, (%edi)
		addw    $4, %dx
		incw    %si
		incl    %ecx
		cmpl    %eax, %ecx
		jne     LBB1_2  # bb
	
into

LBB1_1: # entry.bb_crit_edge
        xorl    %ecx, %ecx
        xorw    %dx, %dx
LBB1_2: # bb
        movl    L_X$non_lazy_ptr, %esi
        movw    %cx, (%esi)
        movl    L_Y$non_lazy_ptr, %esi
        movw    %dx, (%esi)
        addw    $4, %dx
		incl    %ecx
        cmpl    %eax, %ecx
        jne     LBB1_2  # bb

Chris Lattner 36f81fb065 Fix a recovery bug Fariborz and I noticed yesterday. We were producing: 
method.c:4:3: error: use of undeclared identifier 'BADIDENT'
        &BADIDENT, 0
         ^
method.c:5:2: error: expected '}'
};
 ^
method.c:3:14: error: to match this '{'
struct S A = {
             ^

now we only produce:
