Update.
2003-01-26 Andreas Schwab <schwab@suse.de> * sysdeps/wordsize-32/divdi3.c: Export the functions only as compatibility symbols. Remove INTDEF for __divdi3. * sysdeps/wordsize-32/lldiv.c: Don't use __divdi3_internal. * sysdeps/powerpc/powerpc32/divdi3.c: Remove. * sysdeps/powerpc/powerpc32/Makefile (CPPFLAGS-divdi3.c): Don't define. * sysdeps/powerpc/powerpc32/Dist: Remove divdi3.c. 2003-01-24 Jakub Jelinek <jakub@redhat.com> * elf/tls-macros.h: Add SPARC 32-bit definitions. * sysdeps/sparc/sparc32/elf/configure.in: Add TLS check. * sysdeps/sparc/sparc32/dl-machine.h: Add dl_machine_h guards for the first half of the header. Include tls.h. (elf_machine_type_class): Return ELF_RTYPE_CLASS_PLT for TLS relocs too. (elf_machine_rela): Handle TLS relocs. * sysdeps/sparc/dl-tls.h: New file. * sysdeps/unix/sysv/linux/sparc/sparc32/socket.S: Add cancellation support. * sysdeps/sparc/sparc32/sparcv9/hp-timing.h: Use %g6 instead of %g7. * sysdeps/sparc/sparc32/memchr.S: Likewise. * sysdeps/sparc/sparc32/memcpy.S: Likewise. * sysdeps/sparc/sparc32/strcat.S: Likewise. * sysdeps/sparc/sparc32/strchr.S: Likewise. * sysdeps/sparc/sparc32/strcmp.S: Likewise. * sysdeps/sparc/sparc32/strcpy.S: Likewise. * sysdeps/sparc/sparc64/sparcv9b/memcpy.S: Likewise. * sysdeps/sparc/sparc64/hp-timing.h: Likewise. * sysdeps/sparc/sparc64/memcpy.S: Likewise. * sysdeps/sparc/sparc64/stpcpy.S: Likewise. * sysdeps/sparc/sparc64/stpncpy.S: Likewise. * sysdeps/sparc/sparc64/strcat.S: Likewise. * sysdeps/sparc/sparc64/strchr.S: Likewise. * sysdeps/sparc/sparc64/strcmp.S: Likewise. * sysdeps/sparc/sparc64/strcpy.S: Likewise. * sysdeps/sparc/sparc64/strncmp.S: Likewise. * sysdeps/sparc/sparc64/strncpy.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise. 2003-01-24 Andreas Schwab <schwab@suse.de> * elf/dl-close.c (_dl_close): Don't relocate DT_FINI_ARRAY elements, and process them backwards. * elf/Makefile ($(objpfx)tst-array4): New target. ($(objpfx)tst-array4.out): Likewise. (tests) [$(have-initfini-array) = yes]: Add tst-array4. * elf/tst-array4.c: New file. * elf/tst-array4.exp: Likewise. 2003-01-24 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/unix/sysv/linux/powerpc/powerpc64/fe_nomask.c: New file. 2003-01-27 Guido Guenther <agx@sigxcpu.org> * sysdeps/unix/sysv/linux/mips/sysdep.h (SYSCALL_ERROR_LABEL): Define. * sysdeps/unix/sysv/linux/mips/pread.c: Add support for cancellation handling and handle both __NR_pread64 and __NR_pread. * sysdeps/unix/sysv/linux/mips/pread64.c: Likewise. * sysdeps/unix/sysv/linux/mips/pwrite.c: Add support for cancellation handling and handle both __NR_pwrite64 and __NR_pwrite. * sysdeps/unix/sysv/linux/mips/pwrite64.c: Likewise. * sysdeps/unix/mips/sysdep.S: Don't set errno in the _LIBC_REENTRANT case, use register names consistently. 2003-01-27 Wolfram Gloger <wg@malloc.de> * malloc/hooks.c (mem2chunk_check): Check alignment of mem pointer, not of the computed chunk. Bug report from Carlos O'Donell <carlos@baldric.uwo.ca>.
