From 89596f0cfa223a2f2836caa56ed79b8a0996f740 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Tue, 24 Jan 2006 19:57:17 -0500 Subject: Some stuff aparently didn't get committed which was from before the new repository was created. SConscript: There is a new SConscript in the arch/alpha directory which has the alpha specific files. To add files for an arch, a similar file should be created. arch/isa_parser.py: The isa parser now supports include directives. These are done with ##include build/SConstruct: The target directory is passed on so that the architecture specific SConscript can have it. Also, sparc was added as a valid architecture type. arch/alpha/SConscript: This SConscript adds the alpha specific source arch/sparc/isa_desc/operands.h: This sets up the operand types that the sparc isa uses arch/sparc/isa_traits.cc: Implementation of sparc specific things, like a register file with windows build/build_options/default/SPARC_SE: The default options for a sparc syscall emulation build. --HG-- extra : convert_revision : 1afedae61dc8cae0d59d3bf1d41420d929be2efd --- arch/sparc/isa_desc/operands.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 arch/sparc/isa_desc/operands.h (limited to 'arch/sparc/isa_desc') diff --git a/arch/sparc/isa_desc/operands.h b/arch/sparc/isa_desc/operands.h new file mode 100644 index 000000000..77de6c9c4 --- /dev/null +++ b/arch/sparc/isa_desc/operands.h @@ -0,0 +1,33 @@ +def operand_types {{ + 'sb' : ('signed int', 8), + 'ub' : ('unsigned int', 8), + 'shw' : ('signed int', 16), + 'uhw' : ('unsigned int', 16), + 'sw' : ('signed int', 32), + 'uw' : ('unsigned int', 32), + 'sdw' : ('signed int', 64), + 'udw' : ('unsigned int', 64), + 'sf' : ('float', 32), + 'df' : ('float', 64), + 'qf' : ('float', 128) +}}; + +def operands {{ + # Int regs default to unsigned, but code should not count on this. + # For clarity, descriptions that depend on unsigned behavior should + # explicitly specify '.uq'. + 'Rd': IntRegOperandTraits('udw', 'RD', 'IsInteger', 1), + 'Rs1': IntRegOperandTraits('udw', 'RS1', 'IsInteger', 2), + 'Rs2': IntRegOperandTraits('udw', 'RS2', 'IsInteger', 3), + #'Fa': FloatRegOperandTraits('df', 'FA', 'IsFloating', 1), + #'Fb': FloatRegOperandTraits('df', 'FB', 'IsFloating', 2), + #'Fc': FloatRegOperandTraits('df', 'FC', 'IsFloating', 3), + 'Mem': MemOperandTraits('udw', None, + ('IsMemRef', 'IsLoad', 'IsStore'), 4) + #'NPC': NPCOperandTraits('uq', None, ( None, None, 'IsControl' ), 4), + #'Runiq': ControlRegOperandTraits('uq', 'Uniq', None, 1), + #'FPCR': ControlRegOperandTraits('uq', 'Fpcr', None, 1), + # The next two are hacks for non-full-system call-pal emulation + #'R0': IntRegOperandTraits('uq', '0', None, 1), + #'R16': IntRegOperandTraits('uq', '16', None, 1) +}}; -- cgit v1.2.3
