Thu Sep 21 14:11:49 1995 Michael Meissner <meissner@cygnus.com>
* config/tc-ppc.c (ppc_flags): New variable to hold the flag bits
to set in the ELF header.
(md_parse_option): Add support for -mrelocatable-lib. Make both
-mrelocatable and -mrelocatable-lib set ppc_flags.
(md_begin): Set ELF flags with ppc_flags.
Wed Sep 20 13:01:52 1995 Ian Lance Taylor <ian@cygnus.com>
* Makefile.in (maintainer-clean): New target, synonym for
realclean. Add GNU standard maintainer-clean echos.
* doc/Makefile.in (maintainer-clean): New target, synonym for
realclean.
Tue Sep 19 11:31:31 1995 Ian Lance Taylor <ian@cygnus.com>
* config/tc-m68k.c (m68k_ip): Reject immediate operands for '%'.
