Consider:
---
template <typename foo>
void bar() {}
namespace { class C {};}
void (*FP)() = bar<C>;
---
Because 'bar' is instantiated with 'C', a class in an anonymous namespace, this
instantiation can never be shared across other translation units. As such, it
should be marked static, to improve static and dynamic link times and improve
future IPO potential.
On PPC Darwin, the instantion of bar turns into:
.section __TEXT,__textcoal_nt,coalesced,no_toc
.align 2
.weak_definition __Z3barIN21_GLOBAL__N_t.cczMkGAb1CEEvv
.private_extern __Z3barIN21_GLOBAL__N_t.cczMkGAb1CEEvv
.section __TEXT,__textcoal_nt,coalesced,no_toc
.align 2
__Z3barIN21_GLOBAL__N_t.cczMkGAb1CEEvv:
