1997-03-19 01:40 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/sco3.2.4/Dist: New file. * sysdeps/unix/sysv/sysv4/Dist: Add __getpgid.c and __setpgid.c. * sysdeps/unix/bsd/Dist: Add bsdstat.h, setrgid.c, and setruid.c. * sysdeps/unix/sysv/Dist: Add direct.h. * sysdeps/unix/sysv/linux/Dist: Add netinet/tcp.h. * Make-dist ($(tardir).tar): Prefer writing temporary file to $TMPDIR is available. The default is /tmp. * sysdeps/generic/ip.h: Move to... * sysdeps/generic/netinet/ip.h: ...here. * Makefile (tests): Quote $(CC) argument to isomac program. Patch by H.J. Lu <hjl@gnu.ai.mit.edu>. * sysdeps/i386/setjmp.S (__setjmp): Fix fatal bug where 0 argument is placed in wrong place on the stack. Reported by Marc Lehmann <mlehmann@hildesheim.sgh-net.de>. * sysdeps/tst-setjmp.c: Add new test for above problem. * sysdeps/libm-i387/e_pow.S: Compute PIC addres early. * sysdeps/libm-i387/e_powf.S: Likewise. * sysdeps/libm-i387/e_powl.S: Likewise. 1997-03-18 23:18 Ulrich Drepper <drepper@cygnus.com> * time/offtime.c (__offtime): Change type of `yg' to long int. Reported by a sun <asun@zoology.washington.edu>. 1997-03-18 23:08 a sun <asun@zoology.washington.edu> * sysdeps/unix/sysv/linux/net/if_ppp.h (PPP_VERSION): Define to 2.2.0 to prevent version mismatch. 1997-03-17 19:26 Andreas Jaeger <aj@arthur.pfalz.de> * stdio-common/printf_fphex.c (MIN): Only define MIN if not already defined. 1997-03-14 23:34 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/termbits.h: Leave ioctl numbers in ioctls.h. * elf/rtld.c (_dl_start): Call elf_machine_runtime_setup when the loader first relocates itself. * sysdeps/powerpc/elf/start.c (__start1): Fix bug for static objects. * sysdeps/powerpc/dl-machine.h (elf_machine_rela): Fix bugs in jump slot relocation. Prefer relative branches (some PowerPC chips don't predict absolute branches). (elf_machine_runtime_setup): Simplify and correct expressions. (RTLD_START): Fix bug changing _dl_starting_up. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Added. Deal with strange Linux/PPC padding of initial stack. 1997-03-11 04:14 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/termbits.h: Increase NCCS to 39, for future expansion. * sysdeps/unix/sysv/linux/powerpc/sys/kernel_termios.h: Added. * sysdeps/powerpc/dl-machine.h (elf_machine_rela): Explain why it can't have a switch statement. * sysdeps/powerpc/elf/start.c (__start1): Explain why it can't be static. * sysdeps/powerpc/elf/start.c (_start): Use .previous to avoid confusing gcc's idea of the current section. * sysdeps/powerpc/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE, RTLD_START): Likewise. 1997-03-08 09:10 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/powerpc/dl-machine.h (elf_machine_rela, elf_machine_runtime_setup): Flush data & instruction caches when necessary, for 603/604 support. Add better support for large PLTs. (elf_machine_rela): Remove relocations that wouldn't work if anyone ever used them. Use memcpy for copy reloc, it'll be safe. Never target branch relocations at a PLT entry. * sysdeps/powerpc/bsd-setjmp.S: Make jump to PLT entry if we are generating PIC. * sysdeps/powerpc/bsd-_setjmp.S: Likewise. * sysdeps/powerpc/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/powerpc/clone.S: Likewise. * sysdeps/unix/sysv/linux/powerpc/socket.S: Likewise. * sysdeps/unix/sysv/linux/powerpc/syscall.S: Likewise. * sysdeps/unix/sysv/linux/powerpc/sysdep.h: Likewise. * sysdeps/powerpc/elf/start.c: Clean up. * sysdeps/powerpc/__longjmp.S: Return 'value' as result from setjmp call. * sysdeps/unix/sysv/linux/powerpc/statbuf.h: New file. 1997-03-09 12:36 H.J.
