2002-03-15 Ulrich Drepper <drepper@redhat.com> * sysdeps/i386/i386-mcount.S: Just call __mcount_internal, it is an internal function. Adjust for internal_function calling convention. * sysdeps/i386/machine-gmon.h: Declare and define __mcount_internal as internal_function. * sysdeps/generic/framestate.c: Declare fallback_frame_state_for as hidden. * nss/XXX-lookup.c (DB_LOOKUP_FCT): Add internal_function to declaration and definition. * nss/getXXbyYY_r.c (DB_LOOKUP_FCT): Add internal_function to declaration. * nss/getXXent_r.c: Likewise. * nss/nsswitch.h (db_lookup_function): Add internal_function to definition. * include/time.h: Declare __localtime_r as hidden. * include/grp.h: Declare __getgrent_r as hidden. * include/netdb.h: Declare __gethostent_r, __getnetent_r, __getservent_r, and __getprotoent_r as hidden. * include/pwd.h: Declare __getpwent_r as hidden. * include/shadow.h: Declare __getspent_r as hidden. * include/rpc/netdb.h: Declare __getrpcent_r as hidden. * iconv/gconv_int.h: Declare __gconv_read_conf, __gconv_alias_compare, and __gconv_transliterate as hidden. Add internal_function to __gconv_get_path declaration. * iconv/gconv_int.h: Add internal_function to __gconv_get_path definition. Add attribute_hidden to __gconv_read_conf definition.

/* We need a special version of the `mcount' function since for ix86 it

must not clobber any register. This has several reasons:

- there is a bug in gcc as of version 2.7.2.2 which prohibits the

use of profiling together with nested functions
|

- the ELF `fixup' function uses GCC's regparm feature
