weird errors about property attributes being unknown.

llvm-svn: 57812

crash.m:8:12: error: type name requires a specifier or qualifier
@property (readonlyx, getter=isAwesome) int _awesome;
           ^
crash.m:8:29: error: expected ';' at end of declaration list
@property (readonlyx, getter=isAwesome) int _awesome;
                            ^
crash.m:8:39: error: expected identifier or '('
@property (readonlyx, getter=isAwesome) int _awesome;
                                      ^

we now get:

crash.m:8:12: error: unknown property attribute 'readonlyx'
@property (readonlyx, getter=isAwesome) int _awesome;
           ^

Also, we can eliminate isObjCPropertyAttribute now.

ParseObjCPropertyAttribute.  Before, on this code (where
a comma was forgotten):

@property (readonly getter=isAwesome) int _awesome;

we emitted:

crash.m:9:11: error: expected ')'
@property (readonly getter=isAwesome) int _awesome;
          ^
crash.m:9:37: error: type name requires a specifier or qualifier
@property (readonly getter=isAwesome) int _awesome;
                                    ^
crash.m:9:37: error: expected identifier or '('
crash.m:9:37: error: expected ';' at end of declaration list
crash.m:9:1: error: @property requires fields to be named
@property (readonly getter=isAwesome) int _awesome;
^

now we emit:

crash.m:9:21: error: expected ')'
@property (readonly getter=isAwesome) int _awesome;
                    ^
crash.m:9:11: error: to match this '('
@property (readonly getter=isAwesome) int _awesome;
          ^

Add some fixmes about some apparently objc2 code that is being accepted
in objc1.

where it would reject @required in non-protocols, but then go
ahead and tag methods with required anyway.  Instead, if we see
this in something other than a protocol, just ignore the request.

Also, improve error recovery a bit when we see something bogus 
inside an interface.

to make it easier to understand.  No functionality change.

move it to its own predicate to make it more clear.

can't stick an attributes?

llvm-svn: 57795

of whether a '(' was a grouping paren or the start of a function declarator.
This is PR2796.

Now we eat the attribute before deciding whether the paren is grouping or
not, then apply it to the resultant decl or to the first argument as needed.

One somewhat surprising aspect of this is that attributes interact with
implicit int in cases like this:

void a(x, y) // k&r style function
void b(__attribute__(()) x, y); // function with two implicit int arguments
void c(x, __attribute__(()) y); // error, can't have attr in identifier list.

Fun stuff.

enough, legalize the mask, which may result in it
no longer being a BUILD_VECTOR node (LegalizeDAG
simply ignores the legality or not of vector masks).

The casts<> require that "Decl.h" is included before "Type.h", use reinterpret_cast<> to remove that kind of dependency.

 - Support noreturn on function-typed variables.

 - Extend isFunctionOrMethod to return true for K&R functions and
   provide hasFunctionProto to check if a decl has information about
   its arguments. This code needs some serious cleaning, but works.

 - Add/improve test cases for noreturn and unused.

Patch by Timo Sirainen!

llvm-svn: 57772

the previous patch this one actually passes make check.

"Fix PR2356 on PowerPC: if we have an input and output that are tied together
that have different sizes (e.g. i32 and i64) make sure to reserve registers for
the bigger operand."
