From f671aeab4e17d6dc1c3ca96ac5cb2c3e04570082 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 31 May 1997 00:47:04 +0000 Subject: Update. 1997-05-31 02:33 Ulrich Drepper * io/ftwtest-sh: More tests. * misc/tsearch.c: Rewrite tdestroy_recursive. * libio/libio.h: Define bits for libg++-2.8. 1997-05-30 22:21 Thorsten Kukuk * nis/nss_nis/nis-hosts.c: Same changes as in nss/nss_files/files-hosts.c (Always use inet_pton). * nis/nss_nisplus/nisplus-hosts.c: Likewise. 1997-05-30 09:50 Richard Henderson * manual/maint.texi: ECOFF hasn't been tested in ages and I don't plan on doing so ever again. Don't say alpha-linuxecoff is known to work. * elf/dl-lookup.c: Include . * misc/tsearch.c: Include . * posix/execle.c: Include . * posix/execlp.c: Likewise. * stdio-common/printf_fphex.c: Include . * sunrpc/xdr.c: Include . * sysdeps/generic/memccpy.c: Include only . * sunrpc/clnt_udp.c (clntudp_call): Make fromlen a size_t to fix parameters to network functions. * sunrpc/pmap_rmt.c (clnt_broadcast): Likewise. * sunrpc/svc_tcp.c (svctcp_create): Likewise with `len'. (rendezvous_request): Likewise. * sunrpc/svc_udp.c (svcudp_bufcreate): Likewise. (svcudp_recv): Similar, but go through a local variable. The old code used &xprt->xp_addrlen. Someone should determine if the type of the structure member should be changed instead. * sunrpc/xdr_rec.c (xdrrec_create): Expunge a ptr->int cast warning and transform a nonsense for-loop to a closed form calculation. (fill_input_buf): Another ptr->int warning. * sysdeps/alpha/Makefile: Temporarily turn on -mieee globally. This will last until I figure out how to build a parallel libm_ieee. * sysdeps/alpha/fpu/fclrexcpt.c, * sysdeps/alpha/fpu/fegetenv.c, * sysdeps/alpha/fpu/fegetround.c, * sysdeps/alpha/fpu/feholdexcpt.c, * sysdeps/alpha/fpu/fenvbits.h, * sysdeps/alpha/fpu/fesetenv.c, * sysdeps/alpha/fpu/fesetround.c, * sysdeps/alpha/fpu/feupdateenv.c, * sysdeps/alpha/fpu/fgetexcptflg.c, * sysdeps/alpha/fpu/fraiseexcpt.c, * sysdeps/alpha/fpu/fsetexcptflg.c, * sysdeps/alpha/fpu/ftestexcept.c: New files. There is, btw, a small kernel patch that must be applied as of 2.0.31-pre1 and 2.1.41 for this to work properly. * sysdeps/alpha/fpu/fpu_control.h: Update copyright. Change default FP mode to round to nearest, no exceptions as for Intel. * sysdeps/unix/sysv/linux/alpha/setfpucw.c: Add copyright. (rdfpcr): Use excb rather than trapb. Be more efficient about getting at the fpcr. (wrfpcr): Likewise. (__setfpucw): Reformat. * sysdeps/ieee754/huge_val.h: Change GCC's HUGE_VAL definition to use a single DI-mode integer instead of bytes. This produces better code on Alpha. Similar for HUGE_VALF. * sysdeps/ieee754/nan.h: Similar for NAN. Add NANF and NANL. * sysdeps/libm-ieee754/s_log2.c: Missing */ and weak_alias. * sysdeps/unix/alpha/sysdep.S: Tiny cleanups. * sysdeps/unix/sysv/linux/alpha/syscall.S: Likewise. * sysdeps/unix/sysv/linux/alpha/brk.S: Don't use jmp macro to make sure the stack frame is released the very instruction before the real jump out. * sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/gnu/types.h: Undef some bits we may have gotten from . * sysdeps/unix/sysv/linux/alpha/ioperm.c: Add definition for Miata. 1997-05-30 13:05 Ulrich Drepper * misc/tst-tsearch.c (mangle_tree): Update casts to prevent warnings. 1997-05-29 14:02 Andreas Schwab * sysdeps/unix/sysv/linux/sys/ttydefaults.h (CEOL, CSTATUS): Use correct value for _POSIX_VDISABLE. 1997-05-29 13:59 Andreas Schwab * Makefile (manual/dir-add.texi): Force execution. 1997-05-29 13:57 Andreas Schwab * sysexits.h: New file. 1997-05-29 13:55 Andreas Schwab * stdlib/strfmon.c: Don't run past EOS after `='. 1997-02-27 10:34 Richard Henderson --- sysdeps/alpha/fpu/feupdateenv.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 sysdeps/alpha/fpu/feupdateenv.c (limited to 'sysdeps/alpha/fpu/feupdateenv.c') diff --git a/sysdeps/alpha/fpu/feupdateenv.c b/sysdeps/alpha/fpu/feupdateenv.c new file mode 100644 index 0000000000..816575a134 --- /dev/null +++ b/sysdeps/alpha/fpu/feupdateenv.c @@ -0,0 +1,38 @@ +/* Install given floating-point environment and raise exceptions. + Copyright (C) 1997 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Richard Henderson , 1997. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 of the + License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
