* sysdeps/unix/bsd/pause.c: Moved to sysdeps/unix/common/pause.c. Mon Mar 4 20:17:28 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/adjtime.c: Use INT_MAX instead of LONG_MAX. * sysdeps/unix/sysv/Makefile (sysdep_routines): Don't add s_getdents. * sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Don't add mount, umount. * sysdeps/alpha/__math.h (atan, cabs): New functions. * sysdeps/unix/sysv/linux/alpha/sigsuspend.S: new file (syscall expects set-value, not pointer to it). Sun Feb 25 22:36:10 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/profil-counter.h: New file. * gmon/gmon.c (__bb_head): new variable. (write_hist, write_call_graph, write_bb_counts): new functions. (_mcleanup): modified to call above functions instead of directly writing out gmon.out. * gmon/sys/gmon.h (struct __bb): New type. (struct gmonhdr): Type removed. (struct gmonparam): New member `log_hashfraction'. (GMONVERSION): Macro removed. * gmon/sys/gmon_out.h, gmon/bb_exit_func.c, sysdeps/generic/bb_init_func.c, sysdeps/alpha/bb_init_func.S: new files. * gmon/Makefile (headers): Add sys/gmon_out.h. (routines): Add bb_init_func, bb_exit_func. * gmon/mcount.c: Avoid integer division. Wed Feb 21 23:56:41 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/alpha/setjmp.S: switched order in which sp and fp are passed to match what __sigsetjmp_aux() expects. Tue Feb 20 11:33:46 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/syscalls.list (select, bind, connect, getpeername, getsockname, listen, recv, recvfrom, recvmsg, send, sendmsg, sendto, setsockopt, shutdown, socketpair): added to override same-name assembly file in the parent directory. * stdlib/stdlib.h: add include of sys/types.h in front of random etc declarations to ensure int32_t is declared. * stdlib/random.c, stdlib/random_r.c: replaced "long int" by int32_t where 32 bit integers are required. Also change LONG_MAX into 0x7fffffff since the intent is to turn off the sign bit in a 32 bit integer. * time/offtime.c (__offtime): Use Paul Eggert's code to deal with very large values for "days" (e.g., 64 bit values). Mon Feb 19 22:22:12 1996 David Mosberger-Tang <davidm@azstarnet.com> * stdlib/stdlib.h (__random, __random_r, random_r, struct random_data): use int32_t instead of `long int'. Sat Feb 17 11:29:29 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/ioperm.c: new file. * sysdeps/alpha/ffs.S: new file. * sysdeps/alpha/fabs.c: File removed. * time/tzfile.c (__tzfile_read): counter variable is i, *not* num_transitions! * time/offtime.c: make capable of dealing with very large (64 bit) time_t values. Use old algorithm until a year is reached that is an integer multiple of 400, then use DAYS_PER_400_YEARS to do the remainder in a single division. * sysdeps/generic/ffs.c (ffs): fix variable declarations to be unsigned int, not unsigned long. * string/test-ffs.c (main): add test case with all upper bits set. * stdlib/tst-strtol.c: add tests cases for machines where sizeof(long)==8. * stdlib/testrand.c (main): disallow rand() to return negative integers. * stdlib/testmb.c (main): fix format to use %lx instead of %x. * stdlib/stdlib.h: on 64 bit machines, declare struct random_data, __random(), __random_r, and random_r to return "int" instead of "long int". * stdlib/random_r.c: 64 bit machines use "int" instead of "long int". Similarly, use INT_MAX instead of LONG_MAX. * stdlib/random.c: on 64 bit machines, randtbl[] and __random[] need to operate on "int" instead of "long int". * locale/locfile-hash.c (compute_hashval): make shifted constant a long to avoid loosing bits on 64 bit machines. * dirent/tst-seekdir.c (main): fix confusing comment; print a line to mark point where directory is rewound. Fri Feb 16 15:01:49 1996 David Mosberger-Tang <davidm@azstarnet.com> * time/strftime.c (strftime): any hour > 11 is PM (not > 12!). Wed Feb 14 00:21:17 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/Makefile, sysdeps/unix/sysv/linux/alpha/brk.S, sysdeps/unix/sysv/linux/alpha/fpu_control.c, sysdeps/unix/sysv/linux/alpha/fpu_control.h, 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/pipe.S, sysdeps/unix/sysv/linux/alpha/setfpucw.c, sysdeps/unix/sysv/linux/alpha/sigprocmask.c, sysdeps/unix/sysv/linux/alpha/speed.c, sysdeps/unix/sysv/linux/alpha/start.S, sysdeps/unix/sysv/linux/alpha/syscall.S, sysdeps/unix/sysv/linux/alpha/syscalls.list, sysdeps/unix/sysv/linux/alpha/alpha/regdef.h, sysdeps/unix/sysv/linux/alpha/sysdep.S, sysdeps/unix/sysv/linux/alpha/sysdep.h: New files. * sysdeps/alpha/setjmp_aux.c (__sigsetjmp_aux): restore return address register before returning (gcc 2.7.1 doesn't do it, presumably because $26 is declared as a global variable). * sysdeps/unix/sysv/linux/sys/mman.h: msync was missing "flags" argument. * sysdeps/unix/alarm.c (alarm): do roundup using test & increment instead of multiplication. * sysdeps/posix/sleep.c (sleep): initialize sa_mask to mask of currently blocked signals instead of the empty mask to ensure that execution of alarm handler occurs with none of the currently blocked signals enabled. * sysdeps/unix/alpha/sysdep.h: new file (adapted from OSF/1 version). * sysdeps/unix/bsd/osf/alpha/sysdep.h: include sysdeps/unix/alpha/sysdep.h and removed definitions now in that file. * sysdeps/alpha/divrem.S, sysdeps/alpha/htonl.S, sysdeps/alpha/htons.S, sysdeps/alpha/machine-gmon.h, sysdeps/alpha/_mcount.S, sysdeps/alpha/ntohl.s, sysdeps/alpha/ntohs.s, sysdeps/alpha/strlen.S: New files. * sysdeps/alpha/divl.S, sysdeps/alpha/divlu.S, sysdeps/alpha/divq.S, sysdeps/alpha/divqu.S, sysdeps/alpha/divrem.m4, sysdeps/alpha/macros.m4, sysdeps/alpha/reml.S, sysdeps/alpha/remlu.S, sysdeps/alpha/remq.S, sysdeps/alpha/remqu.S, sysdeps/alpha/strlen.c: Removed. * sysdeps/generic/sbrk.c (__sbrk): argument is of type ptrdiff_t, not int. * sysdeps/alpha/__longjmp.c (__longjmp): moved dummy while loop to end of function to avoid a jump across NOPs. * sysdeps/alpha/Makefile (sysdep_routines): Removed all rules pertaining to integer division/remainder routines since new code doesn't require them. * sunrpc/xdr_mem.c, sunrpc/xdr_stdio.c: Use 4 instead of sizeof(long) where 32 bit quantities are consumed/stored. Various other minor 64-bit cleanups (casting). * sunrpc/xdr.c (xdr_int): test for sizeof(int)==4 to determine whether xdr_long or xdr_short should be used to encode an int. Notice that an xdr_long is 4 bytes independent of the architecture (otherwise no Alpha could interoperate with existing NFS servers, for example). Ditto for enums. * sunrpc/svc_udp.c (svcudp_recv): changed test from 4*sizeof(u_long) to 16 since it really wants 16 bytes. * sunrpc/svc.c (maskp): changed from u_long* to u_int32*. * sunrpc/rpc_cmsg.c (xdr_callmsg), sunrpc/svc_authux.c: increment "buf" pointer by casting it to a char* first since a long* may be 8 bytes or more and oa->oa_length may be any multiple of 4. * sunrpc/rpc/xdr.h (IXDR_GET_LONG, IXDR_PUT_LONG): change casts to u_int32_t (instead of u_long). * sunrpc/clnt_udp.c (clntudp_call): replaced sizeof(u_long) by 4 since it really is testing for 32 bits. Fixed casts to use u_int32 instead of u_long. * sunrpc/xdr_rec.c: Likewise. * sunrpc/clnt_tcp.c (clnttcp_call): replaced u_long by u_int32. * sunrpc/rpc/auth.h: Likewise. * limits.h (LONG_MAX, LONG_MIN, ULONG_MAX): use 64 bit values for Alpha. Tue Mar 19 13:27:49 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> * sysdeps/i386/fpu/__math.h: New file. Contributed by John C. Bowman <bowman@hagar.ph.utexas.edu>. Sun Mar 17 00:28:16 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/posix/clock.c: Don't multiply the return value by CLOCKS_PER_SEC or CLK_TCK. * sysdeps/mach/hurd/getcwd.c: Fail with ENOENT if a parent directory scan finds no match. * posix/unistd.h (setpgrp): Declare no-arg version unless __FAVOR_BSD. * misc/bsd-compat.c (setpgrp): New function, two arg version. * sysdeps/stub/setpgid.c: Remove setpgrp alias. * sysdeps/mach/hurd/setpgid.c: Likewise. * sysdeps/unix/sysv/sysv4/setpgid.c: Likewise. * sysdeps/unix/common/syscalls.list (setpgid): Remove setpgrp alias. * sysdeps/unix/sysv/irix4/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/setpgrp.c: Obsolete file removed. * posix/setpgrp.c (setpgrp): New file. * posix/Makefile (routines): Add setpgrp. Tue Feb 6 12:46:29 1996 David Mosberger-Tang <davidm@azstarnet.com> * libc-symbols.h (weak_alias, weak_symbol): added definitions for ECOFF (HAVE_ECOFF).
