Chris Lattner 016c00a311 when inlining something like this: 
define void @f3(void (i8*)* %__f) ssp {
entry:
  call void %__f(i8* undef)
  unreachable
}

define void @f4(i8* %this) ssp align 2 {
entry:
  call void @f3(void (i8*)* @f2) ssp
  ret void
}

The inliner is turning the indirect call to %__f into a direct
call to F2.  Make the call graph more precise when this happens.

The inliner doesn't revisit call sites introduced by inlining,
so there isn't an easy way to test for this, but a more precise
callgraph is a good thing.

Chris Lattner 055cf267db add a DEBUG call so that -debug lists when CGSCCPM iterates. 
Fix RefreshCallGraph to use CGN->replaceCallEdge instead of hand
rolling its own loop.  replaceCallEdge properly maintains the
reference counts of the nodes, fixing a crash exposed by the
iterative callgraph stuff.

Dan Gohman fd81254190 Move PHINodesToUpdate out of SelectionDAGBuilder and into 
FunctionLoweringInfo, as it isn't SelectionDAG-specific. This isn't
completely natural, as PHI node state is not per-function but rather
per-basic-block, however there's currently no other convenient
per-basic-block state to group it with.

John McCall 8c12dc4351 Use the naming class from the overloaded lookup when access-checking an 
address of overloaded function, instead of assuming that a nested name
specifier was used.  A nested name specifier is not required for static
functions.

Fixes PR6886.

template instantiation, since they cannot be dependent or have
dependent parts. Handle them the simple way.

Douglas Gregor b5186b1d44 When a dependent Objective-C++ message send was able to resolve the 
method being called at template definition time, retain that method
and pass it through to type-checking. We will not perform any lookup
for the method during template instantiation.

Sema::BuildClassMessage; we weren't using it, and template

Douglas Gregor c298ffcb8b Implement template instantiation for Objective-C++ message sends. We 
support dependent receivers for class and instance messages, along
with dependent message arguments (of course), and check as much as we
can at template definition time.

This commit also deals with a subtle aspect of template instantiation
in Objective-C++, where the type 'T *' can morph from a dependent
PointerType into a non-dependent ObjCObjectPointer type.

Daniel Dunbar f812506912 ARM/APCS: Don't respect bit-field types when laying out structures. 
- This fixes the last known ABI issues with ARM/APCS.

 - I've run the first 1k ABITests with '--no-unsigned --no-vector --no-complex'
   on {armv6, armv7} x {-mno-thumb, -mthumb}, and the first 10k tests for armv7
   -mthumb, for both function return types and single argument calls. These all
   pass now (they failed horribly before without --no-bitfield).

Daniel Dunbar 5981377698 IRgen: Fix another case where we generated an invalid access component when we

choosing a better access size up-front.

Daniel Dunbar 5d6c07e0e9 IRgen: Fix case where we might generate an access component with width == 0, if 
we have to narrow the access side immediately (can happen with packed,
-fno-bitfield-type-align).
