1997-03-08 05:30 Ulrich Drepper <drepper@cygnus.com> * argp/Makefile (routines): Add argp-eexst. * argp/argp-ba.c (argp_program_bug_address): Make `const'. * argp/argp-eexst.c: New file. Define exit status variable. * argp/argp-help.c (__argp_state_help): Use argp_err_exit_status variable instead of always exiting with value 1. * argp/argp-pv.c (argp_program_version): Make `const'. * argp/argp.h: Declare argp_err_exit_status. Patches by Miles Bader <miles@gnu.ai.mit.edu>. * locale/programs/localedef.c: Use argp_err_exit_status to terminate with correct value. * inet/rcmd.c (iruserok): Use euidaccess instead of half-hearted switching of UID before opening .rhosts. * libio/vsnprintf.c: Change implementation to follow ISO C 9X proposal. The return value now is always the number of characters which would be written if enough space is available. * manual/stdio.texi: Update description for new behaviour. * locale/locale.h (__locale_t): Don't use __locale_t for struct name and pointer to struct since old gccs cannot keep the namespaces apart. Rename struct to __locale_struct. * locale/duplocale.h: Likewise. * locale/newlocale.h: Likewise. * math/Makefile (headers): Add complex.h and cmathcalls.h. (routines): Remove w_cabs. Add conj, cimag, creal, and cabs. * math/math.h: Undefine __MATHDECL_1, __MATHDECL, and __MATHCALL after use. (signgam): Move declaration to here from mathcalls.h. * math/mathcalls.h (cabs, __cabs_complex, signgam): Remove definition. Correct comment for fmin and fmax. Start implementing complex math function from ISO C 9X. * math/complex.h: New file. * math/cmathcalls.h: New file. * math/cabs.c: New file. * math/cabsf.c: New file. * math/cabsl.c: New file. * math/cimag.c: New file. * math/cimagf.c: New file. * math/cimagl.c: New file. * math/conj.c: New file. * math/conjf.c: New file. * math/conjl.c: New file. * math/creal.c: New file. * math/crealf.c: New file. * math/creall.c: New file. * sysdeps/libm-ieee754/w_cabs.c: Removed. * sysdeps/libm-ieee754/w_cabsf.c: Removed. * sysdeps/libm-ieee754/w_cabsl.c: Removed. * posix/regex.c: Merge with regex sources from Arnold Robbins' version in GNU awk. * posix/regex.h: Likewise.

(testcases.h): New rule to generate header with tests. * posix/TESTS: New file. * posix/TESTS2C.sed.: New file. * posix/runtests.c: New file. * posix/testcases.h: New file. * sysdeps/unix/sysv/linux/poll.c: Test whether poll syscall is available and use fall-back implementation if not. * sysdeps/unix/sysv/linux/syscalls.list: Sort entries. * time/ialloc.c: Update from tzcode1997c. * time/private.h: Likewise. * time/scheck.c: Likewise. * time/tzselect.ksh: Likewise. * time/zdump.c: Likewise. * time/zic.c: Likewise. * time/tzfile.c: Pretty print. 1997-03-06 07:37 Geoff Keating <geoffk@ozemail.com.au> Port to powerpc-*-linux-gnu. Slightly tested, under MkLinux, on a 601. * sysdeps/powerpc/Implies: Added. * sysdeps/powerpc/__longjmp.S: Added. * sysdeps/powerpc/__math.h: Added. * sysdeps/powerpc/bsd-_setjmp.S: Added. * sysdeps/powerpc/bsd-setjmp.S: Added. * sysdeps/powerpc/dl-machine.h: Added. * sysdeps/powerpc/ffs.c: Added. * sysdeps/powerpc/fpu_control.h: Added. * sysdeps/powerpc/jmp_buf.h: Added. * sysdeps/powerpc/setjmp.S: Added. * sysdeps/powerpc/strlen.s: Added. * sysdeps/powerpc/elf/start.c: Added. * sysdeps/powerpc/fpu_control.h: Added. * sysdeps/powerpc/jmp_buf.h: Added. * sysdeps/unix/sysv/linux/powerpc/Dist: Added. * sysdeps/unix/sysv/linux/powerpc/_exit.S: Added. * sysdeps/unix/sysv/linux/powerpc/brk.c: Added. * sysdeps/unix/sysv/linux/powerpc/clone.S: Added. * sysdeps/unix/sysv/linux/powerpc/init-first.h: Added. * sysdeps/unix/sysv/linux/powerpc/ioctl-types.h: Added. * sysdeps/unix/sysv/linux/powerpc/profil.c: Added. * sysdeps/unix/sysv/linux/powerpc/sigreturn.S: Added. * sysdeps/unix/sysv/linux/powerpc/socket.S: Added. * sysdeps/unix/sysv/linux/powerpc/syscall.S: Added. * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Added. * sysdeps/unix/sysv/linux/powerpc/sysdep.c: Added. * sysdeps/unix/sysv/linux/powerpc/sysdep.h: Added. * sysdeps/unix/sysv/linux/powerpc/termbits.h: Added. * sysdeps/unix/sysv/linux/powerpc/sys/syscall.h: Added. 1997-03-05 05:24 Geoff Keating <geoffk@ozemail.com.au> * elf/dl-runtime.c (fixup): Add ELF_FIXUP_RETURNS_ADDRESS switch, because knowing the first instruction of a PowerPC PLT trampoline is not very helpful. 1997-03-04 08:04 Geoff Keating <geoffk@ozemail.com.au> * elf/dl-load.c (ELF_PREFERRED_ADDRESS, ELF_PREFERRED_ADDRESS_DATA, ELF_FIXED_ADDRESS): Added.
