Could you help me to solve this problem?
The ability to answer is dependent upon the quality of the question.
If you case you removed all details that allow anyone from helping you.
Compare your question to:
When I compile:
extern "C" void foo() {
}
I get:
.public foo
foo:
ret
at -O2 using gcc 3.4.3 on arm-elf and when I assemble this with
binutils 2.904, nm shows no foo in the symbol table, is the compiler
broken?
Here we see the input to the compiler, the output from the compiler,
the compilation flags used and so on... That has an answer, and it is
no; further, we could say that as from binutils appears to be broken,
and then have you go ask the binutils people about it.
So, cut down the testcase to a small example, show us the full source
code (gcc -E), the flags used to compile, the .s file produced and the
name of the symbol in question...
