From 2f537933275764e17e38877cd86ac8de2e0eb4f4 Mon Sep 17 00:00:00 2001 From: Geoffrey Noer Date: Tue, 27 Oct 1998 01:03:28 +0000 Subject: [PATCH] Mon Oct 26 14:07:59 1998 Mumit Khan * dllwrap.c (strhash): New function. (main): Use it to supply image base if not supplied by user. (program_version): Up to 0.2.4. Mon Oct 26 14:07:59 1998 Mumit Khan * dlltool.c (add_stdcall_alias): New global. (long_options): Add --add-stdcall-alias option. (main): Handle it. (scan_drectve_symbols): Add alias if --add-stdcall-alias is specified. (scan_filtered_symbols): Likewise. (gen_def_file): Output alias for stdcall syms if appropriate. * binutils.texi (dlltool): Document --add-stdcall-alias option. * dllwrap.c (long_options): Add --add-stdcall-alias option. (main): Handle it. * defparse.y (opt_name): Allow "." in name. * dlltool.c (def_name): Set dll_name from NAME entry in def file. (def_library): Set dll_name from LIBRARY entry in def file. Mon Oct 26 14:07:59 1998 Mumit Khan * dllwrap.c (long_options): --implib synonym for --output-lib. (main): Pass --export-all to dlltool only if specified. (program_version): Up to 0.2.3. Mon Oct 26 14:07:59 1998 Mumit Khan * dllwrap.c (mybasename): New function. (main): Run dlltool to create export definition file and import library file if necessary.
