[Bug c/31782] New: Invalid assembly code on initial dollar signs

["truedfx at gentoo dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

This code compiles fine with gcc:

void a$() {}
int main() { a$(); }

This generates invalid assembly code:

void $() {}
int main() { $(); }

To gas, an initial $ is not allowed in an identifier, but to gcc, it is, so gcc
can't simply copy the function name to the assembly output, unless $ also
becomes an invalid identifier in C.

The code can, of course, compile successfully with -fleading-underscore.
