Hi, Attached is a patch that fixes PR5477 and PR5464 (http://llvm.org/bugs/show_bug.cgi?id=5477 , http://llvm.org/bugs/show_bug.cgi?id=5464).
The problem is ensuring tags and enum constants that are created as part of
a function prototype end up in the scope of the function definition, and
ensuring that they do not incorrectly conflict with identifiers in the
global scope. E.g.:
Const int AA = 5;
int f (enum {AA, BB} e) {
Return AA;
}
Clang currently errors out: test.c:2:15: error: redefinition of 'AA'
The patch attached fixes this, and more complex examples such as:
struct a {
struct b {
int j;
} b;
};
int foo(struct a { struct b { int j; } b; struct b { char glorx; } glorx; }
*);
It introduces some statefulness into Sema, but it appears that Sema is
already stateful so I hope that won't be a problem.
Could someone please review it? (some code taken from the current patch at
PR5464)
Cheers,
James
