d7c44059d4 Only loc::MemRegionVal can be modified. This avoids crashing in RegionStore when a function pointer is used as an argument.

69f9bc24f4 Fix the definition of __builtin_va_list on PPC, which was set to the V4 ABI, not the 
darwin or AIX abis.  This fixes PR2904.

084bc32e0d make codegen reject initializes with designators, like this: 
t.c:1:13: error: cannot codegen this designators yet
int a[10] = {2, 4, [8]=9, 10};

46dcba6d2d add some simple designator testcases. Reject things like this: 
struct foo Y[10] = {
  [4] .arr [2] 4  // expected-error {{expected '=' or another designator}}
};

because the "missing equals" extension only is valid if there 
is exactly one array designator.

initializer, avoiding an extra level of calls for silly things like
'int x = 4'.

f3e58e2ebc This patch continues parser-level implementation of designators: 
1. It introduces new parser level abstractions for designators
   that are used to communicate between parser and sema.
2. This fixes a FIXME where "identifier ':'" was considered to be
   a designator even if it wasn't the first in a designator list.
3. In the "identifier ':'" case, it actually builds the designator
   representation.

22a3735398 Don't give a default argument to ASTContext::getFunctionType for the TypeQuals parameter, it causes subtle bugs where TypeQuals, while necessary, are omitted from the call.
