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.
