2010-08-23X86: Define a noop ExtMachInst.Gabe Black
2010-08-23Loader: Make the load address mask be a parameter of the system rather than ↵Ali Saidi
a constant. This allows one two different OS requirements for the same ISA to be handled. Some OSes are compiled for a virtual address and need to be loaded into physical memory that starts at address 0, while other bare metal tools generate images that start at address 0.

2010-02-12O3PCU: Split loads and stores that cross cache line boundaries.Timothy M. Jones
When each load or store is sent to the LSQ, we check whether it will cross a cache line boundary and, if so, split it in two. This creates two TLB translations and two memory requests. Care has to be taken if the first packet of a split load is sent but the second blocks the cache. Similarly, for a store, if the first packet cannot be sent, we must store the second one somewhere to retry later. This modifies the LSQSenderState class to record both packets in a split load or store. Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA to indicate whether unaligned memory accesses are allowed. This is used throughout the changed code so that compiler can optimise away code dealing with split requests for ISAs that don't need them.
2009-07-08Registers: Add a registers.hh file as an ISA switched header.Gabe Black
This file is for register indices, Num* constants, and register types. copyRegs and copyMiscRegs were moved to utility.hh and utility.cc. --HG-- rename : src/arch/alpha/regfile.hh => src/arch/alpha/registers.hh rename : src/arch/arm/regfile.hh => src/arch/arm/registers.hh rename : src/arch/mips/regfile.hh => src/arch/mips/registers.hh rename : src/arch/sparc/regfile.hh => src/arch/sparc/registers.hh rename : src/arch/x86/regfile.hh => src/arch/x86/registers.hh

2007-07-26X86: Fix argument register indexing.Gabe Black
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg. --HG-- extra : convert_revision : f448a3ca4d6adc3fc3323562870f70eec05a8a1f
2007-06-19Get rid of the immediate and displacement components of the EmulEnv struct ↵Gabe Black
and use them directly out of the instruction. The extra copies are conceptually realistic but are just innefficient as implemented. Also don't use the zeroeth microcode register for general storage since it's now the zero register, and implement a load and a store microops. --HG-- extra : convert_revision : 0686296ca8b72940d961ecc6051063bfda1e932d
