* corefile.c (core_init): Use a separate local variable,
core_sym_bytes, to make the units from bfd_get_symtab_upper_bound more obvious. (core_create_function_syms): Discard cbfd argument. Eliminate `offset' variable and calculate VMA directly. Update all users. * corefile.h (core_create_function_syms): Update prototype. (core_create_line_syms): Likewise. * gprof.c (main): Remove #ifdef PROF_SUPPORT_IMPLEMENTED code. Tidy.
