like:
struct S { struct S {} X; };
with:
t.c:2:19: error: nested redefinition of 'struct'
struct S { struct S {} X; };
^
t.c:2:1: error: previous definition is here
struct S { struct S {} X; };
^

X = sizeof(int (void a));
X = sizeof(int (int, void));
X = sizeof(int (void, ...));
We now emit:
t.c:6:24: error: void argument may not have a name
X = sizeof(int (void a));
^
t.c:7:24: error: 'void' must be the first and only parameter if specified
X = sizeof(int (int, void));
^
t.c:8:19: error: 'void' must be the first and only parameter if specified
X = sizeof(int (void, ...));
^
And we pretty print this correctly (even though void isn't stored in the
arg list of the function type):
X = sizeof(int (void));
However, this approach will have to change to handle typedefs of void.

declarator interface handles all alloc/dealloc issues related to the argument
list. Before the client had to alloc and Declarator did the dealloc.

This lets us pretty print stuff like this:
void foo() {
int X;
X = sizeof(void (*(*)())());
X = sizeof(int(*)(int, float, ...));
X = sizeof(void (*(int arga, void (*argb)(double Y)))(void* Z));
as:
X = sizeof(void (*(*)())())
X = sizeof(int (*)(int, float, ...))
X = sizeof(void (*(int, void (*)(double)))(void *))
Ah the wonders of 'modern' C syntax!

the info. Also, call Actions.ParseParamDeclaratorType instead of
Actions.ParseDeclarator for parameter type lists: we don't want declaration
objects created when parsing a function declarator, we just want type info.
llvm-svn: 39230
parameters: build an array of ParamInfo structures and pass it to the
declarator for safe keeping (it owns the list).
Next step: actually populate the arg array with useful stuff.
llvm-svn: 39229
things like:
t.c:4:10: error: invalid storage class specifier in function declarator
int foo2(auto int Aaslfkasdflkj, register B);

instead of:
t.c:4:19: error: invalid storage class specifier in function declarator
int foo2(auto int Aaslfkasdflkj, register B);

thing properly. This allows us to print types like:
int (*A)[restrict static 4][6];
properly, in addition to representing them properly. :)

fundamentally requires having an AST around, so move all sema to the
AST library. This is the first step, later steps will be needed to
clean up libast.

declarations through the asm streamer. For a testcase like:
int G;
int H, I, *J;
int func() {}
'clang -parse-print-ast' prints:
Read top-level decl: G
Read top-level decl: H
Read top-level decl: I
Read top-level decl: J
Read top-level decl: func
