Update.
2001-05-20 Bruno Haible <haible@clisp.cons.org> * iconvdata/cp1255.c: Completely rewritten. * iconvdata/Makefile (gen-8bit-gap-modules): Remove cp1255. * iconvdata/testdata/WINDOWS-1255: New file. * iconvdata/testdata/WINDOWS-1255..UTF8: New file. * iconvdata/TESTS: Add WINDOWS-1255 test. * iconvdata/CP1255.irreversible: New file. 2001-05-20 Bruno Haible <haible@clisp.cons.org> * iconvdata/cp1258.c: Completely rewritten. * iconvdata/Makefile (gen-8bit-gap-modules): Remove cp1258. * iconvdata/testdata/WINDOWS-1258: New file. * iconvdata/testdata/WINDOWS-1258..UTF8: New file. * iconvdata/TESTS: Add WINDOWS-1258 test. * iconvdata/tst-table-from.c (try): Reset the iconv descriptor before the main call, and flush it afterwards. (utf8_decode): Return a string, possibly containing several Unicode characters. (main): Update all utf8_decode calls. * iconvdata/CP1258.irreversible: New file. 2001-05-20 Bruno Haible <haible@clisp.cons.org> * iconv/gconv.c (__gconv): For flush without output, pass do_flush = 2. * iconv/skeleton.c: Distinguish do_flush = 1 and do_flush = 2. In the first case, set outbuf, outstart, outend, and call PREPARE_LOOP before EMIT_SHIFT_TO_INIT; then pass the output produced by this step down to the next step. In the second case, clear the state without calling EMIT_SHIFT_TO_INIT. * iconvdata/ibm930.c (EMIT_SHIFT_TO_INIT): Use outbuf instead of data->__outbuf, and outend instead of data->__outbufend. * iconvdata/ibm933.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/ibm935.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/ibm937.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/ibm939.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/iso-2022-cn.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/iso-2022-cn-ext.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/iso-2022-jp.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/iso-2022-kr.c (EMIT_SHIFT_TO_INIT): Likewise. * iconvdata/utf-7.c (EMIT_SHIFT_TO_INIT): Likewise. 2001-05-21 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (dl_main): Compute l_map_end for the main program. * elf/dl-sym.c (_dl_sym): Don't check for l_addr == 0. If match == _dl_loaded, caller can still come from the main program. (_dl_vsym): Likewise. * elf/dl-open.c (dl_open_worker): Don't check for l_addr == 0. * elf/dl-error.c (_dl_signal_error): Change NULL objname into "". * elf/restest2.c: New test. * elf/Makefile (tests): Add restest2. (restest2, LDFLAGS-restest2): Add rules.
