pr12552 is a regression from 3.0. In the last run of mozilla's tests when compiling with clang r154343 (https://tbpl.mozilla.org/?tree=Try&rev=3428e6faedb8), that was the only problem on the clang side.
The issue is fixed on trunk. I have attached some patches that fix it
in 3.1. The first one is a full port of the changes on trunk. It also
fixes
template <class T> struct __attribute__((visibility("default"))) A {
static void zed() {}
};
struct H {};
template class A<H>;
with -fvisibility=hidden, for which we currently produce a default
symbol. Trunk and gcc 4.7 produce a hidden one.
The second patch ports just enough of the new logic to fix pr12552.
The third patch is a completely different fix. It is based on what I
did in r154749.
Is one of these OK for 3.1?
Cheers,
Rafael
