Summary: Inaccurate storage class for redeclaration of function
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal

WIP
Testcase:
static void a(void);
void a(void) {};
Run through clang -emit-llvm, this should result in empty output; however, this
isn't the case with trunk clang.
The issue is basically that Sema::MergeFunctionDecl isn't taking into account
the requirements in C99 6.2.2p4 and p5, which taken together mean that "a"
should have internal linkage.
I've attached a patch, but I'm not really sure if it's correct.
