From: Peter Schauer Date: Sat, 10 Sep 1994 08:50:10 +0000 (+0000) Subject: * corelow.c (add_solib_stub): Copy to_sections changes from X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=26a859ec838aa00054f5504cbe3dc2e09771ed81;p=binutils-gdb.git * corelow.c (add_solib_stub): Copy to_sections changes from core_ops to current_target after adding the shared libraries. * partial-stab.h (N_EXCL), dbxread.c (add_old_header_file, find_corresponding_bincl_psymtab): Change `repeated header not seen' error to a complaint, simplify complaint. * procfs.c (signalname, errnoname): Make `name' const. * symfile.c (reread_symbols): Use filename from old BFD to reopen the objfile. * values.c (record_latest_value): Don't record value in the history chain until we are sure there won't be an error. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index e0ea7a977bd..775a08240c3 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,16 @@ +Sat Sep 10 01:43:28 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de) + + * corelow.c (add_solib_stub): Copy to_sections changes from + core_ops to current_target after adding the shared libraries. + * partial-stab.h (N_EXCL), dbxread.c (add_old_header_file, + find_corresponding_bincl_psymtab): Change `repeated header not seen' + error to a complaint, simplify complaint. + * procfs.c (signalname, errnoname): Make `name' const. + * symfile.c (reread_symbols): Use filename from old BFD to + reopen the objfile. + * values.c (record_latest_value): Don't record value in the + history chain until we are sure there won't be an error. + Fri Sep 9 15:52:09 1994 J.T.
