1997-03-20 06:07 Ulrich Drepper <drepper@cygnus.com> * sysdeps/powerpc/dl-machine.h: Fix typo in last change. * sysdeps/unix/sparc/sysdep.h: Update copyright. 1997-03-19 15:13 Miguel de Icaza <miguel@nuclecu.unam.mx> * linuxthreads/sysdeps/sparc/pt-machine (RELEASE): Fix. * stdlib/tst-strtol.c: Save the value of errno, printf may modify it. * sysdeps/sparc/DEFS.h [HAVE_ELF]: Use type @function in the FUNC macro on ELF systems. * sysdeps/sparc/configure.in: Fix. * sysdeps/sparc/dl-machine.h: Fix OPCODE_CALL. * sysdeps/sparc/setjmp.S: Fix my bugs. * sysdeps/unix/sysv/linux/sparc/Dist: Add start.c, fork.S, and pipe.S. * sysdeps/unix/sysv/linux/sparc/Makefile: Define asm-CPPFLAGS and as-FLAGS-.so. * sysdeps/unix/sysv/linux/sparc/syscalls.list: Add fork, pipe, and syscall. * sysdeps/unix/sysv/linux/sparc/fork.S: New file. * sysdeps/unix/sysv/linux/sparc/pipe.S: New file. * sysdeps/unix/sysv/linux/sparc/socket.S: Fix. * sysdeps/unix/sysv/linux/sparc/sysdep.h: Fix. * elf/dl-lookup.c (do_lookup): Return true if we found a weak symbol. (_dl_lookup_symbol): Test against the symbol being global not against the symbol being not weak (fixes important problem with the SPARC linker) * sysdeps/unix/sysv/linux/sparc/brk.c: Fix. * sysdeps/unix/sysv/linux/sparc/start.c: Startup code for Linux/SPARC (while I get my asmCPPFLAGS-so variable). 1997-03-20 01:49 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_tanhl.c (__tanhl): Correct handling of -inf. * elf/dl-reloc.c (RESOLVE): Don't try to resolve local symbols.
