From: Gabe Black Date: Sun, 12 Feb 2006 22:38:10 +0000 (-0500) Subject: Pseudo instructions are now passed whatever instructions they need by the decoder... X-Git-Tag: m5_2.0_beta1~87^2~104 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=19e5efed03dd7e0ff003ea804b285ee490adf061;p=gem5.git Pseudo instructions are now passed whatever instructions they need by the decoder, rather than extracting them explicitly. This lets most of the pseudo instruction code to be shared across architectures. SConscript: Moved pseudo_inst.hh from targetarch to full system sources arch/alpha/SConscript: Moved pseudo_inst.cc out of the alpha specific sources arch/alpha/isa/decoder.isa: The decoder now pulls out the arguments for the pseudo instructions based on the alpha ABI arch/alpha/isa/main.isa: Registers 16, 17 and 18 are used to get parameters for the pseudo instructions and can be referred to explicitly sim/pseudo_inst.cc: Changed some include paths to reflect that pseudo_inst.hh is now outside of the alpha directory. Also, instead of extracting their parameters directly, they're passed in as regular function arguments. sim/pseudo_inst.hh: Changed the function prototypes to include the functions parameters, now that they aren't extracted from the execution context. --HG-- rename : arch/alpha/pseudo_inst.cc => sim/pseudo_inst.cc rename : arch/alpha/pseudo_inst.hh => sim/pseudo_inst.hh extra : convert_revision : 76ce768cf1d8a838aa7b64878a7ab4c4215ac999 --- diff --git a/SConscript b/SConscript index 0206141fc..fc2e6ae0b 100644 --- a/SConscript +++ b/SConscript @@ -292,6 +292,7 @@ full_system_sources = Split(''' mem/functional/physical.cc sim/system.cc + sim/pseudo_inst.cc ''') # These are now included by the architecture specific SConscript @@ -347,10 +348,10 @@ targetarch_files = Split(''' ecoff_machdep.h ev5.hh faults.hh - pseudo_inst.hh stacktrace.hh vtophys.hh ''') +# pseudo_inst.hh # isa_traits.hh # osfpal.hh # byte_swap.hh diff --git a/arch/alpha/SConscript b/arch/alpha/SConscript index 2c98125bc..8bf408c06 100644 --- a/arch/alpha/SConscript +++ b/arch/alpha/SConscript @@ -244,7 +244,6 @@ arch_full_system_sources = Split(''' arch/alpha/arguments.cc arch/alpha/ev5.cc arch/alpha/osfpal.cc - arch/alpha/pseudo_inst.cc arch/alpha/stacktrace.cc arch/alpha/vtophys.cc ''') diff --git a/arch/alpha/isa/decoder.isa b/arch/alpha/isa/decoder.isa index 29124f191..aff8571e9 100644 --- a/arch/alpha/isa/decoder.isa +++ b/arch/alpha/isa/decoder.isa @@ -768,23 +768,23 @@ decode OPCODE default Unknown::unknown() { AlphaPseudo::m5exit_old(xc->xcBase()); }}, No_OpClass, IsNonSpeculative); 0x21: m5exit({{ - AlphaPseudo::m5exit(xc->xcBase()); + AlphaPseudo::m5exit(xc->xcBase(), R16); }}, No_OpClass, IsNonSpeculative); 0x30: initparam({{ Ra = xc->xcBase()->cpu->system->init_param; }}); 0x40: resetstats({{ - AlphaPseudo::resetstats(xc->xcBase()); + AlphaPseudo::resetstats(xc->xcBase(), R16, R17); }}, IsNonSpeculative); 0x41: dumpstats({{ - AlphaPseudo::dumpstats(xc->xcBase()); + AlphaPseudo::dumpstats(xc->xcBase(), R16, R17); }}, IsNonSpeculative); 0x42: dumpresetstats({{ - AlphaPseudo::dumpresetstats(xc->xcBase()); + AlphaPseudo::dumpresetstats(xc->xcBase(), R16, R17); }}, IsNonSpeculative); 0x43: m5checkpoint({{ - AlphaPseudo::m5checkpoint(xc->xcBase()); + AlphaPseudo::m5checkpoint(xc->xcBase(), R16, R17); }}, IsNonSpeculative); 0x50: m5readfile({{ - AlphaPseudo::readfile(xc->xcBase()); + R0 = AlphaPseudo::readfile(xc->xcBase(), R16, R17, R18); }}, IsNonSpeculative); 0x51: m5break({{ AlphaPseudo::debugbreak(xc->xcBase()); @@ -793,7 +793,7 @@ decode OPCODE default Unknown::unknown() { AlphaPseudo::switchcpu(xc->xcBase()); }}, IsNonSpeculative); 0x53: m5addsymbol({{ - AlphaPseudo::addsymbol(xc->xcBase()); + AlphaPseudo::addsymbol(xc->xcBase(), R16, R17); }}, IsNonSpeculative); } diff --git a/arch/alpha/isa/main.isa b/arch/alpha/isa/main.isa index c082df8c8..a2860f17b 100644 --- a/arch/alpha/isa/main.isa +++ b/arch/alpha/isa/main.isa @@ -160,7 +160,9 @@ def operands {{ 'FPCR': (' ControlReg', 'uq', 'Fpcr', None, 1), # The next two are hacks for non-full-system call-pal emulation 'R0': ('IntReg', 'uq', '0', None, 1), - 'R16': ('IntReg', 'uq', '16', None, 1) + 'R16': ('IntReg', 'uq', '16', None, 1), + 'R17': ('IntReg', 'uq', '17', None, 1), + 'R18': ('IntReg', 'uq', '18', None, 1) }}; //////////////////////////////////////////////////////////////////// diff --git a/arch/alpha/pseudo_inst.cc b/arch/alpha/pseudo_inst.cc deleted file mode 100644 index d6f622ba2..000000000 --- a/arch/alpha/pseudo_inst.cc +++ /dev/null @@ -1,256 +0,0 @@ -/* - * Copyright (c) 2003-2005 The Regents of The University of Michigan - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are - * met: redistributions of source code must retain the above copyright - * notice, this list of conditions and the following disclaimer; - * redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution; - * neither the name of the copyright holders nor the names of its - * contributors may be used to endorse or promote products derived from - * this software without specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS - * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT - * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR - * A PARTICULAR PURPOSE ARE DISCLAIMED.
