/* This routine is called at the beginning of functions compiled with -p
or -pg. The A/UX libraries call mcount%, but gas cannot generate
symbols with embedded percent signs. Previous ports of GCC to A/UX
have done things like (1) assemble a stub routine with the native
assembler, or (2) assemble a stub routine with gas and edit the object
file. This solution has the advantage that it can interoperate with
the A/UX version and can be used in an eventual port of glibc to A/UX. */
