[cfe-dev] clang trunk: extern "C"/static problem

[Richtarsky, Martin]

Hi,

it seems there is a bug in current trunk with regards to the symbols that are generated. At least clang 3.1, gcc 4.3.4 and gcc 4.8 behave differently here.

test.cpp:

extern "C"
{

static void __attribute__((__used__)) func(char *a, char b)
{
}

}

clang++ test.cpp

nm -C test*.o shows these generated symbols for the different compilers:

test_clang31.o:
0000000000000000 t func

test_clang33.o:
0000000000000000 t func(char*, char)

test_gcc43.o:
                 U __gxx_personality_v0
0000000000000000 t func

test_gcc48.o:
0000000000000000 t func


It looks like the static in conjunction with the extern "C" is causing a problem here. Should I file a bug?

Best regards,
Martin
