Gabe Black	7b73c36f5d	X86: Ensure that the decoder's internal ExtMachInst is completely initialized. ... There are some bits of some fields of the ExtMachInst which are not actually used for anything but are included in the hash of an ExtMachInst for simplicity and efficiency. This change makes sure the decoder's internal working ExtMachInst is completely initialized, even these unused bits, so that there isn't any nondeterministic behavior, no valgrind messages about uninitialized variables, and no potential false misses/redundant entries in the decode cache.	2012-06-04 10:43:08 -07:00
Gabe Black	19df4e94ee	ISA,CPU: Generalize and split out the components of the decode cache. ... This will allow it to be specialized by the ISAs. The existing caching scheme is provided by the BasicDecodeCache in the GenericISA namespace and is built from the generalized components. --HG-- rename : src/cpu/decode_cache.cc => src/arch/generic/decode_cache.cc	2012-05-26 13:45:12 -07:00
Gabe Black	0cba96ba6a	CPU: Merge the predecoder and decoder. ... These classes are always used together, and merging them will give the ISAs more flexibility in how they cache things and manage the process. --HG-- rename : src/arch/x86/predecoder_tables.cc => src/arch/x86/decoder_tables.cc	2012-05-26 13:44:46 -07:00
Gabe Black	eae1e97fb0	ISA: Make the decode function part of the ISA's decoder.	2012-05-25 00:55:24 -07:00
Gabe Black	82a228bd43	Decode: Make the Decoder class defined per ISA. ... --HG-- rename : src/cpu/decode.cc => src/arch/generic/decoder.cc rename : src/cpu/decode.hh => src/arch/generic/decoder.hh	2012-05-25 00:53:37 -07:00
