Gabe Black	ff7b89beee	The process of going from an instruction definition to an instruction to be returned by the decoder has been fleshed out more. The following steps describe how an instruction implementation becomes a StaticInst. 1. Microops are created. These are StaticInsts use templates to provide a basic form of polymorphism without having to make the microassembler smarter. 2. An instruction class is created which has a "templated" microcode program as it's docstring. The template parameters are refernced with ^ following by a number. 3. An instruction in the decoder references an instruction template using it's mnemonic. The parameters to it's format end up replacing the placeholders. These parameters describe a source for an operand which could be memory, a register, or an immediate. It it's a register, the register index is used. If it's memory, eventually a load/store will be pre/postpended to the instruction template and it's destination register will be used in place of the ^. If it's an immediate, the immediate is used. Some operand types, specifically those that come from the ModRM byte, need to be decoded further into memory vs. register versions. This is accomplished by making the decode_block text for these instructions another case statement based off ModRM. 4. Once all of the template parameters have been handled, the instruction goes throw the microcode assembler which resolves labels and creates a list of python op objects. If an operand is a register, it uses a % prefix, an immediate uses $, and a label uses @. If the operand is just letters, numbers, and underscores, it can appear immediately after the prefix. If it's not, it can be encolsed in non nested {}s. 5. If there is a single "op" object (which corresponds to a single microop) the decoder is set up to return it directly. If not, a macroop wrapper is created around it. In the future, I'm considering seperating the operand type specialization from the template substitution step. A problem this introduces is that either the template arguments need to be kept around for the specialization step, or they need to be re-extracted. Re-extraction might be the way to go so that the operand formats can be coded directly into the micro assembler template without having to pass them in as parameters. I don't know if that's actually useful, though. src/arch/x86/isa/decoder/one_byte_opcodes.isa: src/arch/x86/isa/microasm.isa: src/arch/x86/isa/microops/microops.isa: src/arch/x86/isa/operands.isa: src/arch/x86/isa/microops/base.isa: Implemented polymorphic microops and changed around the microcode assembler syntax. --HG-- extra : convert_revision : e341f7b8ea9350a31e586a3d33250137e5954f43	2007-04-04 23:35:20 +00:00

Gabe Black	10fe8b05db	Made the "data" field of store queue entries into a character array. It's sized to match an IntReg which was what it used to be, but we might want to make it something architecture independent. All data is now endian converted before entering the store queue entries which simplifies store to load forwarding in "trans endian" simulations, and makes twin memory ops work. src/cpu/o3/lsq_unit.hh: src/cpu/o3/lsq_unit_impl.hh: fixed twin memory operations. --HG-- extra : convert_revision : 8fb97f98e285cd22413e06e146fa82392ac2a590	2007-04-03 22:53:26 +00:00
Kevin Lim	98c8cd0b36	Fix a memory leak. Hopefully this fixes the longer running benchmarks. --HG-- extra : convert_revision : 89eff82642ff181a9b95c77c4d2bf620ca837113	2007-04-03 14:25:24 -04:00

Gabe Black	61c56ffeaf	A batch of changes and fixes. Macroops are now generated automatically, multiops do alot more of what they're supposed to (excluding memory operands), and microops are slightly more implemented. --HG-- extra : convert_revision : 518059f47e11df50aa450d4a322ef2ac069c99c9	2007-04-03 15:01:09 +00:00
Gabe Black	0ce6936e7d	Zero out ModRM if the byte isn't there, and fix some displacement size stuff. --HG-- extra : convert_revision : f43abf33a223a665b30098c63011fb162200d5e6	2007-04-03 14:56:24 +00:00
Kevin Lim	ec09e5ad6f	Remove/comment out DPRINTFs that were causing a segfault. The removed ones were unnecessary. The commented out ones could be useful in the future, should this problem get fixed.

Gabe Black	7fcc9d2106	Made the MultiOp format do a little more. It now sets up single microop instructions to return an instance of the right class. The code to decode register numbers and generate loads and stores still needs to be added. Also, a syntax for specifying operands as sources, destinations, or both needs to be established. Multipl microop instructions are also not handled, pending real macroop generation support. --HG-- extra : convert_revision : 1a0a4b36afce8255e23e3cdd7a85c1392dda5f72	2007-03-29 17:57:19 +00:00
Gabe Black	e67a207ad3	Add a microcode assembler. A microcode "program" is a series of statements. Each statement has an optional label at the beginning, a capitilized microcode class name which is roughly equivalent to a mnemonic in a regular ISA, and then an optional series of operands seperated by white space. The operands are either a decimal constant, a label, or a code fragment surrounded by non nested {}s. Labels are a letter or underscore followed by letters, underscores, or digits. The syntax for describing code segments might need to be changed if a need arrises to have {}s in the code itself. --HG-- extra : convert_revision : 8e5cfdd1a3c9a7e3731fdf6acd615ee82ac2b9b7	2007-03-29 17:57:18 +00:00
Kevin Lim	5c3f724174	Override addPrivateSplitL1Caches function in order to automatically set the tgts_per_mshr of the caches to 20. This is needed otherwise things will potentially lock up when using the O3CPU because the caches can run out of targets, and then not respond. Remove this hack once the caches eventually get fixed. --HG-- extra : convert_revision : 8c61ac1b6182f57ebbe3bcfeddb5a4f4334d7bc0	2007-03-29 12:25:47 -04:00
