From fb1e4ffce36db7b63b85bc3a64917bda0c8ac84b Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Thu, 8 Feb 2007 21:39:04 +0000 Subject: [PATCH] * features/Makefile, features/arm-with-iwmmxt.xml, features/gdbserver-regs.xsl, features/number-regs.xsl, features/sort-regs.xsl, features/xscale-iwmmxt.xml: New files. * regformats/arm-with-iwmmxt.dat: Generate. * NEWS: Mention iWMMXt. * gdb.arch/iwmmxt-regs.c, gdb.arch/iwmmxt-regs.exp: New. * Makefile.in (OBS): Add $(XML_BUILTIN). (XML_DIR, XML_TARGET, XML_FILES, XML_BUILTIN): New. (clean): Update. (target.xml, xml-builtin.c, stamp-xml, arm-with-iwmmxt.o) (arm-with-iwmmxt.c): New. * config.in, configure: Regenerate. * configure.ac: Check for iWMMXt. Handle srv_xmltarget, srv_xmlbuiltin, and srv_xmlfiles. Define USE_XML. * configure.srv: Mention srv_xmltarget and srv_xmlfiles. (arm*-*-linux*): Add iWMMXt and regset support. * linux-arm-low.c (PTRACE_GETWMMXREGS, PTRACE_SETWMMXREGS): Define. (arm_fill_gregset, arm_store_gregset, arm_fill_wmmxregset) (arm_store_wmmxregset, target_regsets): New. * server.c (get_features_xml): Take annex argument. Check builtin XML documents. (handle_query): Handle multiple annexes. --- gdb/ChangeLog | 8 +++ gdb/NEWS | 3 + gdb/features/Makefile | 49 ++++++++++++++ gdb/features/arm-with-iwmmxt.xml | 13 ++++ gdb/features/gdbserver-regs.xsl | 47 ++++++++++++++ gdb/features/number-regs.xsl | 47 ++++++++++++++ gdb/features/sort-regs.xsl | 11 ++++ gdb/features/xscale-iwmmxt.xml | 44 +++++++++++++ gdb/gdbserver/ChangeLog | 19 ++++++ gdb/gdbserver/Makefile.in | 25 ++++++++ gdb/gdbserver/config.in | 3 + gdb/gdbserver/configure | 63 +++++++++++++++++- gdb/gdbserver/configure.ac | 33 ++++++++++ gdb/gdbserver/configure.srv | 14 +++- gdb/gdbserver/linux-arm-low.c | 71 +++++++++++++++++++++ gdb/gdbserver/server.c | 37 +++++++++-- gdb/regformats/arm-with-iwmmxt.dat | 51 +++++++++++++++ gdb/testsuite/ChangeLog | 4 ++ gdb/testsuite/gdb.arch/iwmmxt-regs.c | 88 ++++++++++++++++++++++++++ gdb/testsuite/gdb.arch/iwmmxt-regs.exp | 78 +++++++++++++++++++++++ 20 files changed, 698 insertions(+), 10 deletions(-) create mode 100644 gdb/features/Makefile create mode 100644 gdb/features/arm-with-iwmmxt.xml create mode 100644 gdb/features/gdbserver-regs.xsl create mode 100644 gdb/features/number-regs.xsl create mode 100644 gdb/features/sort-regs.xsl create mode 100644 gdb/features/xscale-iwmmxt.xml create mode 100644 gdb/regformats/arm-with-iwmmxt.dat create mode 100644 gdb/testsuite/gdb.arch/iwmmxt-regs.c create mode 100644 gdb/testsuite/gdb.arch/iwmmxt-regs.exp diff --git a/gdb/ChangeLog b/gdb/ChangeLog index de6f607024..6ec59a485f 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,11 @@ +2007-02-08 Daniel Jacobowitz + + * features/Makefile, features/arm-with-iwmmxt.xml, + features/gdbserver-regs.xsl, features/number-regs.xsl, + features/sort-regs.xsl, features/xscale-iwmmxt.xml: New files. + * regformats/arm-with-iwmmxt.dat: Generate. + * NEWS: Mention iWMMXt. + 2007-02-08 Daniel Jacobowitz * Makefile.in (arm-tdep.o, eval.o, target-descriptions.o) diff --git a/gdb/NEWS b/gdb/NEWS index 864f4d0c60..b81b3b69de 100644 --- a/gdb/NEWS +++ b/gdb/NEWS @@ -22,6 +22,9 @@ a local file or over the remote serial protocol. for architectures which have implemented the support (currently only ARM). +* The GDB remote stub, gdbserver, now supports the XScale iWMMXt +coprocessor. + * New commands set mem inaccessible-by-default diff --git a/gdb/features/Makefile b/gdb/features/Makefile new file mode 100644 index 0000000000..3442f8b602 --- /dev/null +++ b/gdb/features/Makefile @@ -0,0 +1,49 @@ +# Copyright (C) 2007 Free Software Foundation, Inc. + +# This file is part of GDB. + +# 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 2 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.
