Wed May 29 00:57:37 1996 David Mosberger-Tang <davidm@azstarnet.com>
* time/Makefile (tests): Add test-tz.
* time/test-tz.c: New test.
* time/clocktest.c: Rewrite to test more meaningfully.
* sysdeps/unix/sysv/linux/syscalls.list: Add bdflush,
create_module, delete_module, get_kernel_syms, init_module,
klogctl.
* sysdeps/unix/sysv/linux/sys/param.h (MAXSYMLINKS): Define as 5
instead of SYMLOOP_MAX, which is nowhere to be found.
* sysdeps/unix/sysv/linux/sys/msq_buf.h,
sysdeps/unix/sysv/linux/sys/sem_buf.h,
sysdeps/unix/sysv/linux/sys/shm_buf.h [__USE_MISC]: Add more
control ops and datastructures.
* sysdeps/unix/sysv/linux/sys/io.h: New file declaring low-level
I/O related functions.
* sysdeps/unix/sysv/linux/sys/kdaemon.h: New file declaring kernel
daemon related functions/operations.
* sysdeps/unix/sysv/linux/sys/klog.h: New file declaring kernel
logging related functions/operations.
* sysdeps/unix/sysv/linux/sys/module.h: New file declaring kernel
module related functions/operations.
* sysdeps/unix/sysv/linux/speed.c: Only do "mention this twice" hack
for non-Alpha based Linux systems.
* sysdeps/unix/sysv/linux/alpha/speed.c: Remove.
* sysdeps/unix/sysv/linux/Makefile (headers): Add sys/module.h,
sys/io.h, sys/klog.h, and sys/kdaemon.h.
* sysdeps/unix/sysdep.h (END): Define empty END macro for
platforms that don't need some sort of end directive at the
end of functions.
* sysdeps/unix/make-syscalls.sh: Emit END($strong) at end of
syscall wrapper to allow correct generation of debugging
information.
* sysdeps/unix/alpha/sysdep.h (END): Redefine to use .end
directive for both ELF and ECOFF.
(ret): Delete macro. It was a dangerous macro and unnecessary
since the Alpha assemblers recognizes "ret" as a macro themselves.
* sysdeps/gnu/utmpbits.h (struct utmp): Move ut_tv behind
ut_session to guarantee long alignment. This is important for
Linux/Alpha since ut_tv.tv_sec is 32 bits and time_t is 64 bits.
This will all get cleaned up as programs start to use ut_tv
instead ut_time.
* sysdeps/alpha/divrem.h: Include <sysdep.h> instead of <*/regdef.h>.
* sysdeps/alpha/bsd-_setjmp.S (setjmp): Renamed entry point to
_setjmp.
* sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S,
sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S,
sysdeps/alpha/copysign.S, sysdeps/alpha/divrem.h,
sysdeps/alpha/fabs.S, sysdeps/alpha/ffs.S, sysdeps/alpha/htonl.S,
sysdeps/alpha/htons.S, sysdeps/alpha/memchr.S,
sysdeps/alpha/setjmp.S, sysdeps/alpha/strlen.S,
sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S,
sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S,
sysdeps/unix/sysv/linux/alpha/llseek.S,
sysdeps/unix/sysv/linux/alpha/pipe.S,
sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/sysdep.S: Use END macro instead of
.end directive.
* csu/initfini.c (_fini): Tell gcc that _fini is not a leaf
function by having it contain a dummy function call.
* configure.in (config_machine): Don't make ELF the default for
Linux/Alpha just yet (use --with-elf instead).
(.init/.fini check): Generate .text to ensure function start and
end are in same section.
* sysdeps/unix/bsd/osf/alpha/brk.S,
sysdeps/unix/sysv/linux/alpha/brk.S (__curbrk): Store the entire
break value, not just the low 32 bits to accomodate large
memories.
Tue May 28 10:46:04 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/unix/sysv/linux/alpha/brk.S: Rather than attempt to
dynamically resolve _end for initializing __curbrk, support the
brk(0) query idiom.
* sysdeps/alpha/bb_init_func.S: Don't make `init' an external symbol.
* sysdeps/alpha/bsd-_setjmp.S: The function is _setjmp not setjmp.
Sun May 26 22:17:38 1996 Richard Henderson <rth@tamu.edu>
* stdlib/lcong48_r.c, stdlib/seed48_r.c, stdlib/strtod.c,
stdlib/strtol.c: Include <string.h> for mem* and str* fns used.
Thu May 23 02:15:56 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/Makefile (headers): Add sys/io.h,
sys/klog.h, and sys/kdaemon.h.
* sysdeps/unix/sysv/linux/sys/io.h: New file.
* sysdeps/unix/sysv/linux/sys/klog.h: Ditto.
* sysdeps/unix/sysv/linux/sys/kdaemon.h: Ditto.
* sysdeps/unix/alpha/sysdep.h (ret): Remove macro. It is
dangerous and unnecessary since both OSF/1 as and gas define "ret"
as a pseudo-instruction.
Sat Jun 1 17:18:21 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* time/tzset.c (__tzset): Clear tz_rules name pointers after freeing
them. Bug found by David Mosberger-Tang.
* sysdeps/posix/tempname.c (__stdio_gen_tempname): Use __ptr_t instead
of PTR.
* extra-lib.mk (extra-objs): Use patsubst intead of $(A:=B) syntax
to work around Make bug when A contains var ref.
Fri May 31 18:27:52 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* string/string.h [__USE_MISC]: Declare basename; OSF/1 puts it here.
* sysdeps/unix/sysv/linux/syscalls.list (getpgid, setpgid): Define __
strong names and [gs]etpgid as weak aliases.
* math/math_private.h (GET_LDOUBLE_EXP): Add missing backslash.

Thu Jun 13 17:25:11 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/generic/memcmp.c: Add prototype decls for internal fns.
* locale/programs/locale.c: Include string.h.
* sunrpc/xdr_stdio.c (xdrstdio_getlong), sunrpc/xdr_rec.c
(xdrrec_getlong), sunrpc/xdr_mem.c (xdrmem_getlong): Make sure
appropriate sign-extension is performed on machines with
sizeof(long) > 4.
* sunrpc/xdr.c (xdr_int, xdr_u_int): If sizeof(long)==8 and
sizeof(int)<sizeof(long), we need to go through a temporary
variable.
* locale/programs/ld-numeric.c: Include <alloca.h>
* libio/stdio.h (__libc_fatal): Add prototype.
* libio/cleanup.c: Use __P() to declare prototype when __STDC__ is
in efect.
* libio/iopopen.c (read_or_write, parent_end, child_end): Declare
volatile to avoid "might get clobbered by longjmp" warning.
* features.h (__KERNEL_STRICT_NAMES): Define __KERNEL_STRICT_NAMES
unless _LOOSE_KERNEL_NAMES is in effect (which, with high
probability is a sure loser).
* sysdeps/unix/sysv/linux/gnu/types.h (__KERNEL_STRICT_NAMES): Remove.
* sysdeps/unix/bsd/osf/alpha/start.S (errno): Removed.
* sysdeps/unix/sysv/linux/alpha/start.S: Ditto.
* misc/paths.h (_PATH_MAN): Change from /usr/share/man to /usr/man
to be Linux FSSTND compliant.
Mon Jun 10 17:50:31 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/pipe.S: Use PSEUDO.
* sysdeps/unix/sysv/linux/alpha/sysdep.S,
sysdeps/unix/sysv/linux/alpha/brk.S,
sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S,
sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S,
sysdeps/unix/sysv/linux/alpha/llseek.S,
sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/syscall.S: Rename syscall_error to
__syscall_error to avoid intruding application name space.
* sysdeps/unix/sysv/linux/alpha/sysdep.h: Rename __NR_get?id
to SYS_get?id so that syscall stubs in sysdeps/unix define
these syscalls in terms of getxpid/getxuid/getxgid.
* sysdeps/unix/_exit.S, sysdeps/unix/getegid.S,
sysdeps/unix/geteuid.S, sysdeps/unix/getppid.S,
sysdeps/unix/execve.S, sysdeps/unix/fork.S,
sysdeps/unix/syscall.S: Terminate syscall with PSEUDO_END.
* sysdeps/unix/make-syscalls.sh, sysdeps/unix/sysdep.h
(PSEUDO_END): Rename END() to PSEUDO_END().
* sysdeps/unix/alpha/sysdep.h: Move error-handling code in PSEUDO
to PSEUDO_END to improve branch-prediction. Include .frame
directive to make syscalls debugabble.
(PSEUDO_END): New macro.
* sysdeps/unix/alpha/sysdep.h, sysdeps/alpha/bb_init_func.S,
sysdeps/unix/sysv/linux/alpha/brk.S: Use ldiq instead of ldi since
latter is illegal under DEC Unix.
* sysdeps/unix/alpha/sysdep.S: Renamed from
sysdeps/unix/sysv/linux/alpha/sysdep.S. This file works for OSF/1
as well.
* sysdeps/unix/bsd/osf/alpha/sysdep.S: Remove (note that the
EWOULDBLOCK -> EAGAIN mapping was unnecessary since
EWOULDBLOCK==EAGAIN under DEC Unix and Linux/Alpha).
* sysdeps/alpha/divrem.h: Use retaddr instead of ra as the return
address register in the .frame directive.
* sysdeps/alpha/copysign.c: Remove.
* sunrpc/rpc/types.h: Include <sys/param.h> and <netinet/in.h> to
avoid RPC definitions of INADDR_LOOPBACK and/or MAXHOSTNAMELEN.
* errno.h: Move __END_DECLS to correct place to make file
compilable under c++.
* dirent/dirent.h: Document _DIRENT_HAVE_D_OFF macro. Define
d_ino only if <direntry.h> hasn't defined d_fileno.
* configure.in (HAVE_ASM_WEAKEXT_DIRECTIVE): Reverse order of
arguments to weakext to make .weakext detection work on ECOFF systems.
* FAQ: Add Linux/Alpha to list of supported platforms. Mention
that _validuser() has been replaced by __ivaliduser().
Thu Jun 6 21:39:38 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/bsd/sun/sunos4/tcsetattr.c (tcsetattr): Declare cmd
as unsigned long, not as int (to avoid incorrect int->long
promotion).
