/* Conversion module for ISO-2022-CN.
Update. 2000-03-28 Ulrich Drepper <drepper@redhat.com> * iconvdata/TESTS: Use UCS-2BE instead of UCS2. * iconv/loop.c: Define get16, get32, put16, and put32 macros to allow as well reading from/writing to unaligned addresses on machines which don't support this in hardware. Use FCTNAME macro to define function name. Include the file a second time for platforms which need special unaligned handling. * iconv/skeleton.c: Define get16u, get32u, put16u, and put32u macros to access potentially unaligned addresses. These macros are intended to be used only outside the loops. (unaligned): New definition. In case the machine can handle unaligned access define as zero. Otherwise as a variable which is initialized as nonzero in case the buffer passed in at runtime is unaligned with respect to the character set encoding involved. Call aligned or unaligned looop functions according to unaligned variable. * iconvdata/8bit-gap.c: Use get16, get32, put16, and put32 instead of direct casting pointer to potentially handle unaligned memory accesses. * iconvdata/8bit-generic.c: Likewise. * iconvdata/ansi_x3.110.c: Likewise. * iconvdata/big5.c: Likewise. * iconvdata/euc-cn.c: Likewise. * iconvdata/euc-jp.c: Likewise. * iconvdata/euc-kr.c: Likewise. * iconvdata/euc-tw.c: Likewise. * iconvdata/gbk.c: Likewise. * iconvdata/iso-2022-cn.c: Likewise. * iconvdata/iso-2022-jp.c: Likewise. * iconvdata/iso-2022-kr.c: Likewise. * iconvdata/iso646.c: Likewise. * iconvdata/iso_6937-2.c: Likewise. * iconvdata/iso_6937.c: Likewise. * iconvdata/johab.c: Likewise. * iconvdata/sjis.c: Likewise. * iconvdata/t.61.c: Likewise. * iconvdata/uhc.c: Likewise. * iconvdata/unicode.c: Likewise. * iconvdata/utf-16.c: Likewise. * locale/programs/simple-hash.c: Little optimizations. Remove K&R prototypes. * malloc/Versions [libc] (GLIBC_2.2): Add mcheck_check_all. * malloc/mcheck.c (mcheck_check_all): Renamed from check_all and made public. * malloc/mcheck.h (mcheck_check_all): Declare. * stdio-common/Makefile (tests): Add tst-obprintf.
