From 5578c6a39e8f07df43db05560d847fb83f6d6692 Mon Sep 17 00:00:00 2001 From: Olaf Barthel Date: Sat, 19 Nov 2005 17:11:22 +0000 Subject: [PATCH] - Added for C99, and the (yet unimplemented) functions feclearexcept(), fegetenv(), fegetexceptflag(), fegetround(), feholdexcept(), feraiseexcept(), fesetenv(), fesetexceptflag(), fetestexcept(), fetestround() and feupdateenv(). - Replaced the old pow() implementation. However, powf() may need to be changed to set a domain error. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@15062 87f5fb63-7c3d-0410-a384-fd976d0f7a62 --- library/GNUmakefile.68k | 13 ++- library/GNUmakefile.os4 | 13 ++- library/changes | 9 +++ library/fenv_feclearexcept.c | 53 +++++++++++++ library/fenv_fegetenv.c | 53 +++++++++++++ library/fenv_fegetexceptflag.c | 53 +++++++++++++ library/fenv_fegetround.c | 53 +++++++++++++ library/fenv_feholdexcept.c | 53 +++++++++++++ library/fenv_feraiseexcept.c | 53 +++++++++++++ library/fenv_fesetenv.c | 53 +++++++++++++ library/fenv_fesetexceptflag.c | 53 +++++++++++++ library/fenv_fetestexcept.c | 53 +++++++++++++ library/fenv_fetestround.c | 53 +++++++++++++ library/fenv_feupdateenv.c | 53 +++++++++++++ library/include/fenv.h | 110 ++++++++++++++++++++++++++ library/math_headers.h | 3 +- library/math_pow.c | 140 ++++++++++++++++----------------- library/smakefile | 13 ++- 18 files changed, 806 insertions(+), 78 deletions(-) create mode 100644 library/fenv_feclearexcept.c create mode 100644 library/fenv_fegetenv.c create mode 100644 library/fenv_fegetexceptflag.c create mode 100644 library/fenv_fegetround.c create mode 100644 library/fenv_feholdexcept.c create mode 100644 library/fenv_feraiseexcept.c create mode 100644 library/fenv_fesetenv.c create mode 100644 library/fenv_fesetexceptflag.c create mode 100644 library/fenv_fetestexcept.c create mode 100644 library/fenv_fetestround.c create mode 100644 library/fenv_feupdateenv.c create mode 100644 library/include/fenv.h diff --git a/library/GNUmakefile.68k b/library/GNUmakefile.68k index 93fc2ef..3c4d07d 100644 --- a/library/GNUmakefile.68k +++ b/library/GNUmakefile.68k @@ -1,5 +1,5 @@ # -# $Id: GNUmakefile.68k,v 1.73 2005-10-20 07:19:15 obarthel Exp $ +# $Id: GNUmakefile.68k,v 1.74 2005-11-19 17:11:22 obarthel Exp $ # # :ts=8 # @@ -542,6 +542,17 @@ MATH_LIB = \ complex_creal.o \ complex_crealf.o \ complex_creall.o \ + fenv_feclearexcept.o \ + fenv_fegetenv.o \ + fenv_fegetexceptflag.o \ + fenv_fegetround.o \ + fenv_feholdexcept.o \ + fenv_feraiseexcept.o \ + fenv_fesetenv.o \ + fenv_fesetexceptflag.o \ + fenv_fetestexcept.o \ + fenv_fetestround.o \ + fenv_feupdateenv.o \ math_acos.o \ math_acosf.o \ math_acosh.o \ diff --git a/library/GNUmakefile.os4 b/library/GNUmakefile.os4 index b1daf53..1feb3cf 100644 --- a/library/GNUmakefile.os4 +++ b/library/GNUmakefile.os4 @@ -1,5 +1,5 @@ # -# $Id: GNUmakefile.os4,v 1.85 2005-11-04 09:35:02 obarthel Exp $ +# $Id: GNUmakefile.os4,v 1.86 2005-11-19 17:11:22 obarthel Exp $ # # :ts=8 # @@ -579,6 +579,17 @@ MATH_LIB = \ complex_creal.o \ complex_crealf.o \ complex_creall.o \ + fenv_feclearexcept.o \ + fenv_fegetenv.o \ + fenv_fegetexceptflag.o \ + fenv_fegetround.o \ + fenv_feholdexcept.o \ + fenv_feraiseexcept.o \ + fenv_fesetenv.o \ + fenv_fesetexceptflag.o \ + fenv_fetestexcept.o \ + fenv_fetestround.o \ + fenv_feupdateenv.o \ math_acos.o \ math_acosf.o \ math_acosh.o \ diff --git a/library/changes b/library/changes index 56826f9..de54bb2 100644 --- a/library/changes +++ b/library/changes @@ -1,3 +1,12 @@ +- Added for C99, and the (yet unimplemented) functions + feclearexcept(), fegetenv(), fegetexceptflag(), fegetround(), + feholdexcept(), feraiseexcept(), fesetenv(), fesetexceptflag(), + fetestexcept(), fetestround() and feupdateenv(). + +- Replaced the old pow() implementation.
