arch/alpha/isa/decoder.isa: Fixed up Alpha to pass the syscall number directly to the syscall function. arch/mips/isa/decoder.isa: Fixed up MIPS to pass the syscall number directly to the syscall function. arch/mips/isa/operands.isa: Added an R2 operand which is passed to the syscall function as the syscall number to use. --HG-- extra : convert_revision : 066d486cd6a2761b29e413c6d526c268788975f3
2006-04-14These fixes now allow all of the 20 mips tests to work properly!Korey Sewell
Floating Point Mips Tests still need to be added, tested, and debugged. arch/mips/isa/decoder.isa: Fix mult and multu instructions. This semantic error causes the problem: <int64> = <int32> * <int32>. Although I was placing the output into a 64-bit integer the multiply was just doing a 32-bit multiply so the solution is to just use the 'sd' & 'ud' operands so that the ISA parser will use the int64_t and uint64_t types in calculation. arch/mips/isa/formats/int.isa: Trace output fix. Don't print first comma unless there is a destination register for sure! --HG-- extra : convert_revision : 2c503dca70b104fed0b58454975f745dd3cc2eee

2006-03-28Make .isa-file ##include file paths relative to including file.Steve Reinhardt
Makes .isa files cleaner and simplifies scanner too. Simplified scanner to work under both old and new versions of scons. arch/SConscript: Simplify .isa scanner... seems to work with both scons 0.96.1 and 0.96.91 now.

Makes .isa files cleaner and simplifies scanner too. Partial rewrite of include-handling code to use cool re.sub() feature where you can specify a function to provide the replacement string. Minor cleanup of error-handling code. Also got rid of '#!' at top to make caller choose which python interpreter is used (since SPARC now requires 2.4 to build, we may need to do that via scons in the future). --HG-- rename : arch/mips/isa/formats.isa => arch/mips/isa/formats/formats.isa extra : convert_revision : 15a3920fa3aaf80cd94083eda853aa4e49425045

and file name changes ... arch/mips/isa/decoder.isa: add at least BasicOp Format to most if not all instructions --HG-- rename : arch/mips/isa/formats/basic.format => arch/mips/isa/formats/basic.isa rename : arch/mips/isa/formats/branch.format => arch/mips/isa/formats/branch.isa rename : arch/mips/isa/formats/fp.format => arch/mips/isa/formats/fp.isa rename : arch/mips/isa/formats/int.format => arch/mips/isa/formats/int.isa rename : arch/mips/isa/formats/mem.format => arch/mips/isa/formats/mem.isa rename : arch/mips/isa/formats/noop.format => arch/mips/isa/formats/noop.isa rename : arch/mips/isa/formats/tlbop.format => arch/mips/isa/formats/tlbop.isa rename : arch/mips/isa/formats/trap.format => arch/mips/isa/formats/trap.isa rename : arch/mips/isa/mips.isa => arch/mips/isa/main.isa extra : convert_revision : 0b2f3aee13fee3e0e25c0c746af4216c4a596391
2006-02-07Actually we do need a separate class for Integer Ops with Immediates!!!Korey Sewell
The extra class is needed because of the necessisty of an immediate member variable. Also, added some 'very modest' python code to choose between the IntOp and the IntImmOp based on the instruction name ... --HG-- extra : convert_revision : f109c12418202a99b40e270360134e8335739836
2006-02-07name changes ... minor IntOP format changeKorey Sewell
arch/mips/isa/formats/int.format: Looks like Integer Ops with Immediates may not need their own separate class because all those instructions are distinct from their reg-reg counterparts --HG-- rename : arch/mips/isa/bitfields.def => arch/mips/isa/bitfields.isa rename : arch/mips/isa/decoder.def => arch/mips/isa/decoder.isa rename : arch/mips/isa/formats.def => arch/mips/isa/formats.isa rename : arch/mips/isa/includes.h => arch/mips/isa/includes.isa rename : arch/mips/isa/operands.def => arch/mips/isa/operands.isa extra : convert_revision : 8e354b4232b28c0264d98d333d55ef8b5a6589cc
