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.
