From 4cfcd3b333987a8040c1682e1766a1aeb2941a7d Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 17 Jan 2021 04:52:42 -0500 Subject: [PATCH] sim: common: modernize gennltvals.sh It's not 1996 anymore, so stop writing shell code like it is, and rewrite it with modern POSIX shell standards. This makes it much more user friendly. Then regenerate the file with latest newlib sources to verify. --- sim/ChangeLog | 7 + sim/common/Makefile.in | 2 +- sim/common/gennltvals.sh | 321 ++++++++++++++++++++++++++++----------- sim/common/gentvals.sh | 74 --------- sim/common/nltvals.def | 7 + 5 files changed, 244 insertions(+), 167 deletions(-) delete mode 100755 sim/common/gentvals.sh diff --git a/sim/ChangeLog b/sim/ChangeLog index d8f530996e6..fd368d6d67f 100644 --- a/sim/ChangeLog +++ b/sim/ChangeLog @@ -1,3 +1,10 @@ +2021-01-18 Mike Frysinger + + * Makefile.in (headers): Change args to gennltvals.sh. + * gennltvals.sh: Rewrite from scratch. + * gentvals.sh: Delete. + * nltvals.def: Regen. + 2021-01-15 Mike Frysinger * configure.ac: Delete AC_CONFIG_SUBDIRS(testsuite) call. diff --git a/sim/common/Makefile.in b/sim/common/Makefile.in index 4191b107e2f..33cd788737c 100644 --- a/sim/common/Makefile.in +++ b/sim/common/Makefile.in @@ -82,7 +82,7 @@ headers: rootme=`pwd` ; \ cd $(srcdir) ; \ rm -f nltvals.new ; \ - $(SHELL) $(abs_srcdir)/gennltvals.sh $(SHELL) $(srcroot) "$(CPP_FOR_TARGET)" > nltvals.new ; \ + $(SHELL) $(abs_srcdir)/gennltvals.sh --cpp "$(CPP_FOR_TARGET)" --srcroot $(srcroot) --output nltvals.new ; \ $(SHELL) $(srcroot)/move-if-change nltvals.new nltvals.def .c.o: diff --git a/sim/common/gennltvals.sh b/sim/common/gennltvals.sh index 79180335b62..005fa5b2368 100755 --- a/sim/common/gennltvals.sh +++ b/sim/common/gennltvals.sh @@ -1,33 +1,137 @@ #! /bin/sh -# Generate nltvals.def, a file that describes various newlib/libgloss -# target values used by the host/target interface. +# Copyright (C) 1996-2021 Free Software Foundation, Inc. # -# Syntax: /bin/sh gennltvals.sh shell srcroot cpp - -shell=$1 -srcroot=$2 -cpp=$3 - -srccom=$srcroot/sim/common -if [ -d "${srcroot}/newlib" ]; then - # If newlib is manually in the same source tree, use it. - newlibroot=${srcroot} -else - # Else assume it's alongside the gdb/binutils repo. - newlibroot=${srcroot}/../newlib -fi - -echo '/* Newlib/libgloss macro values needed by remote target support. */' -echo '/* This file is machine generated by gennltvals.sh. */' - -$shell ${srccom}/gentvals.sh "" errno ${newlibroot}/newlib/libc/include \ - "errno.h sys/errno.h" 'E[[:upper:][:digit:]]*' "${cpp}" - -$shell ${srccom}/gentvals.sh "" signal ${newlibroot}/newlib/libc/include \ - "signal.h sys/signal.h" 'SIG[[:upper:][:digit:]]*' "${cpp}" - -$shell ${srccom}/gentvals.sh "" open ${newlibroot}/newlib/libc/include \ - "fcntl.h sys/fcntl.h sys/_default_fcntl.h" 'O_[[:upper:][:digit:]]*' "${cpp}" +# This file is part of the GNU simulators. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program 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.
