From 7799b7b3350fdcadc6dfb8821fb49b7772c96701 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 15 Apr 1997 01:38:39 +0000 Subject: Update. 1997-04-15 03:14 Ulrich Drepper * wcsmbs/wcsstr.c: Add weak alias wcswcs for Unix98 compliance. * math/Makefile (libm-calls): Add s_sincos and s_cproj. * math/mathcalls.h: Add prototype for sincos. * sysdeps/i386/fpu/__math.h: Warn about restriction on arguments to inlined sin and cos function. Define functions new in ISO C 9X when __USE_ISOC9X is defined. Add optimized version of finite. Rewrite sincos function to handle too large arguments. * sysdeps/libm-i387/s_cos.S: Better code alignment. * sysdeps/libm-i387/s_cosl.S: Likewise. * sysdeps/libm-i387/s_sin.S: Likewise. * sysdeps/libm-i387/s_sinl.S: Likewise. * sysdeps/libm-i387/s_finite.S: Yet better code. * sysdeps/libm-i387/s_finitef.S: Likewise. * sysdeps/libm-i387/s_sincos.S: New file. * sysdeps/libm-i387/s_sincosf.S: New file. * sysdeps/libm-i387/s_sincosl.S: New file. * sysdeps/libm-ieee754/s_sincos.c: New file. * sysdeps/libm-ieee754/s_sincosf.c: New file. * sysdeps/libm-ieee754/s_sincosl.c: New file. * sysdeps/libm-ieee754/s_ccosh.c: Change to use sincos function. * sysdeps/libm-ieee754/s_ccoshf.c: Likewise. * sysdeps/libm-ieee754/s_ccoshl.c: Likewise. * sysdeps/libm-ieee754/s_cexp.c: Likewise. * sysdeps/libm-ieee754/s_cexpf.c: Likewise. * sysdeps/libm-ieee754/s_cexpl.c: Likewise. * sysdeps/libm-ieee754/s_csinh.c: Likewise. * sysdeps/libm-ieee754/s_csinhf.c: Likewise. * sysdeps/libm-ieee754/s_csinhl.c: Likewise. * sysdeps/libm-ieee754/s_ctan.c: Likewise. * sysdeps/libm-ieee754/s_ctanf.c: Likewise. * sysdeps/libm-ieee754/s_ctanl.c: Likewise. * sysdeps/libm-ieee754/s_ctanh.c: Likewise. * sysdeps/libm-ieee754/s_ctanhf.c: Likewise. * sysdeps/libm-ieee754/s_ctanhl.c: Likewise. * sysdeps/libm-ieee754/s_cosl.c: Correct check for range. * sysdeps/libm-ieee754/s_sinl.c: Likewise. * sysdeps/libm-ieee754/s_roundtol.c: Fix typos. * sysdeps/libm-ieee754/s_roundtoll.c: Likewise. * nis/Makefile (services): Mention nisplus before compat. * nis/nis_call.c (__do_niscall): Change type of variable server_len to prevent warning. * nis/nss_compat/compat-grp.c (getgrent_next_file_plusgroup): Add cast to prevent warning. * nis/nss_compat/compat-pwd.c (getpwent_next_file_plususer): Likewise. * nis/nss_compat/compat-spwd.c (getspent_next_file_plususer): Likewise. * nis/nss_nisplus/nisplus-hosts.c (_nss_nisplus_parse_hostent): Change type of variable `i' to prevent warning. * nis/nss_nisplus/nisplus-network.c (_nss_nisplus_parse_netent): Likewise. * nis/nss_nisplus/nisplus-proto.c (_nss_nisplus_parse_protoent): Likewise. * nis/nss_nisplus/nisplus-rpc.c (_nss_nisplus_parse_rpcent): Likewise. * nis/nss_nisplus/nisplus-service.c (_nss_nisplus_parse_servent): Likewise. * sysdeps/generic/Dist: Remove old math implementation files. * sysdeps/generic/mathimpl.h: Removed. * sysdeps/generic/trig.h: Removed. * sysdeps/generic/sincos.c: Removed. * sysdeps/generic/asincos.c: Removed. * sysdeps/generic/exp__E.c: Removed. * sysdeps/generic/log__L.c: Removed. 1997-04-13 17:18 Wolfram Gloger * malloc/malloc.c (fREe): Small optimization.

It may be that we are only running out of mmapped regions, and other arenas cannot be enlarged sufficiently. (new_heap, malloc_extend_top): Handle top_pad more consistently, i.e. only in new_heap(). 1997-04-13 21:10 Philip Blundell * sysdeps/posix/Makefile: Don't try to build and run mk-stdiolim if cross-compiling. * configure.in: Recognise "...linuxaout" OS names and turn off ELF. * configure.in: Add ARM support. * sysdeps/arm/Implies: New file. * sysdeps/arm/__longjmp.S: New file. * sysdeps/arm/bsd-_setjmp: New file. * sysdeps/arm/bsd-setjmp: New file. * sysdeps/arm/bytesex.h: New file. * sysdeps/arm/fpu_control.h: New file. * sysdeps/arm/jmp_buf.h: New file. * sysdeps/arm/setjmp.h: New file. * sysdeps/arm/sysdep.h: New file. * sysdeps/unix/arm/config.h: New file. 1997-04-14 04:03 Ulrich Drepper * sysdeps/libm-ieee754/s_cproj.c: New file. * sysdeps/libm-ieee754/s_cprojf.c: New file. * sysdeps/libm-ieee754/s_cprojl.c: New file. --- sysdeps/libm-i387/s_cos.S | 1 + sysdeps/libm-i387/s_cosl.S | 1 + sysdeps/libm-i387/s_finite.S | 7 ++++--- sysdeps/libm-i387/s_finitef.S | 7 ++++--- sysdeps/libm-i387/s_sin.S | 1 + sysdeps/libm-i387/s_sincos.S | 48 +++++++++++++++++++++++++++++++++++++++++++ sysdeps/libm-i387/s_sincosf.S | 48 +++++++++++++++++++++++++++++++++++++++++++ sysdeps/libm-i387/s_sincosl.S | 48 +++++++++++++++++++++++++++++++++++++++++++ sysdeps/libm-i387/s_sinl.S | 1 + 9 files changed, 156 insertions(+), 6 deletions(-) create mode 100644 sysdeps/libm-i387/s_sincos.S create mode 100644 sysdeps/libm-i387/s_sincosf.S create mode 100644 sysdeps/libm-i387/s_sincosl.S (limited to 'sysdeps/libm-i387') diff --git a/sysdeps/libm-i387/s_cos.S b/sysdeps/libm-i387/s_cos.S index f75e98060b..ac8b1459d9 100644 --- a/sysdeps/libm-i387/s_cos.S +++ b/sysdeps/libm-i387/s_cos.S @@ -14,6 +14,7 @@ ENTRY(__cos) testl $0x400,%eax jnz 1f ret + .align ALIGNARG(4) 1: fldpi fadd %st(0) fxch %st(1) diff --git a/sysdeps/libm-i387/s_cosl.S b/sysdeps/libm-i387/s_cosl.S index f41fc19958..61c9010c99 100644 --- a/sysdeps/libm-i387/s_cosl.S +++ b/sysdeps/libm-i387/s_cosl.S @@ -16,6 +16,7 @@ ENTRY(__cosl) testl $0x400,%eax jnz 1f ret + .align ALIGNARG(4) 1: fldpi fadd %st(0) fxch %st(1) diff --git a/sysdeps/libm-i387/s_finite.S b/sysdeps/libm-i387/s_finite.S index 384fc1c79e..198eb809a9 100644 --- a/sysdeps/libm-i387/s_finite.S +++ b/sysdeps/libm-i387/s_finite.S @@ -5,9 +5,10 @@ #include ENTRY(__finite) - movl 8(%esp),%eax - orl $0x800fffff, %eax - incl %eax + movl 8(%esp) + movl $0xFFEFFFFF,%ecx + subl %eax,%ecx + xorl %ecx,%eax,%eax shrl $31, %eax ret END (__finite) diff --git a/sysdeps/libm-i387/s_finitef.S b/sysdeps/libm-i387/s_finitef.S index 51b4d0d536..dabb71a115 100644 --- a/sysdeps/libm-i387/s_finitef.S +++ b/sysdeps/libm-i387/s_finitef.S @@ -6,9 +6,10 @@ ENTRY(__finitef) movl 4(%esp),%eax - orl $0x807fffff, %eax - incl %eax - shrl $31, %eax + movl $0xFF7FFFFF,%ecx + subl %eax,%ecx + xorl %ecx,%eax + shrl $31,%eax ret END (__finitef) weak_alias (__finitef, finitef) diff --git a/sysdeps/libm-i387/s_sin.S b/sysdeps/libm-i387/s_sin.S index f048e5278b..eb22d7e98b 100644 --- a/sysdeps/libm-i387/s_sin.S +++ b/sysdeps/libm-i387/s_sin.S @@ -14,6 +14,7 @@ ENTRY(__sin) testl $0x400,%eax jnz 1f ret + .align ALIGNARG(4) 1: fldpi fadd %st(0) fxch %st(1) diff --git a/sysdeps/libm-i387/s_sincos.S b/sysdeps/libm-i387/s_sincos.S new file mode 100644 index 0000000000..fe99f42d18 --- /dev/null +++ b/sysdeps/libm-i387/s_sincos.S @@ -0,0 +1,48 @@ +/* Compute sine and cosine of argument. + Copyright (C) 1997 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 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.
