Tue Mar 19 14:18:42 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> 

* 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/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).

/* Assembly stub to invoke _mcount(). Compiler generated code calls
this stub after executing a function's prologue and without saving any
registers. It is therefore necessary to preserve a0..a5 as they may
contain function arguments. To work correctly with frame- less
functions, it is also necessary to preserve ra. Finally, division
routines are invoked with a special calling convention and the
compiler treats those calls as if they were instructions. In
particular, it doesn't save any of the temporary registers (caller
saved registers). It is therefore necessary to preserve all
caller-saved registers as well

holds the return address of the function's caller (selfpc and frompc,
respectively in gmon.c language...). */

/* I/O access is restricted to ISA port space (ports 0..65535).
Modern devices hopefully are sane enough not to put any performance
critical registers in i/o space.
On the first call to ioperm() or _sethae(), the entire (E)ISA port
space is mapped into the virtual address space at address io.base.
mprotect() calls are then used to enable/disable access to ports. Per
page, there are PAGE_SIZE>>IO_SHIFT I/O ports (e.g., 256 ports on a
Low Cost Alpha based system using 8KB pages).
Keep in mind that this code should be able to run in a 32bit address
space. It is therefore unreasonable to expect mmap'ing the entire
sparse address space would work (e.g., the Low Cost Alpha chip has an
I/O address space that's 512MB large!). */

* This is for COMPATIBILITY with Linux/x86 only. Linux/Alpha system

* arbitrary 64bit values in v0 (because negative values are not
* mistaken as error numbers). However, C allows to return only one
* value so the interface below folds the error indication passed in
* a3 back into v0: it sets v0 to -errno if an error occurs. Thus,
* no negative 64bit numbers can be returned. To avoid this problem,
* use assembly stubs wherever possible/convenient.
*
* Usage:
*
* long syscall(syscall_number, arg1, arg2, arg3, arg4, arg5)
*
* syscall_number = the index of the system call we're invoking
* arg1-arg5 = up to 5 integer arguments to the system call
*
* We need to do some arg shifting: the kernel expects the
* syscall number in v0 and the first five args in a0-a4.
