Bug ID: 50477
Summary: -fsemantic-interposition breaks extern inline
Product: clang
Version: trunk
Hardware: All
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
Assignee: [email protected]

consider
void foo_good();
extern inline void foo()
{
foo_good();
}
void bar()
{
foo();
}
using: -fsemantic-interposition -fPIC -O2
expected: no reference to foo, only to foo_good.
got: interposable call to foo.
with -O0 i expect a local call to foo that is not interposable.
(i don't think iso c requires either way, but
gcc implements it the described way on elf
platforms and existing software relies on it.
at least on linux targets clang should follow.)
