* gprof.c (default_excluded_list): Add "__mcount". * gprof.c (main): Change ifdef __osf__ to __alpha__. * gmon_io.c (gmon_out_read): If BSD44_FORMAT is defined, get the profiling rate from the header. * gmon.h (struct raw_phdr): Only include pad if both __alpha__ and __osf__ are defined. Add new fields if BSD44_FORMAT is defined. * alpha.h (MIN_INSN_SIZE): Define. * core.c (MIN_INSN_SIZE): If not defined, define as 1. (core_sym_class): Ignore debugging symbols. (core_create_line_syms): Use MIN_INSN_SIZE when gathering line information.
