(pretty much the same as in the other assembler file).
I must say I'm completely lost in where symbols defined in comdat sections may
be referenced and where not, can one reference them in code sections and not
data sections, or only comdat code sections or what? I thought it is pretty
much a normal thing to reference comdat functions in both code and data/rodata
sections, how else
could one do say:
__attribute__((noinline, noipa)) inline void foo () {}
void bar () { foo (); }
void (*p) () = foo;
void (*const q) () = foo;
void (*const *r) () = &q;
