2014-08-13mips: Remove unused private members to fix compile-time warningAndreas Sandberg
Certain versions of clang complain about unused private members if they are not used. This changeset removes such members from the MIPS-specific classes to silence the warning.
2014-05-31style: eliminate equality tests with true and falseSteve Reinhardt
Using '== true' in a boolean expression is totally redundant, and using '== false' is pretty verbose (and arguably less readable in most cases) compared to '!'. It's somewhat of a pet peeve, perhaps, but I had some time waiting for some tests to run and decided to clean these up. Unfortunately, SLICC appears not to have the '!' operator, so I had to leave the '== false' tests in the SLICC code.
2013-06-03arch: Create a method to finalize physical addressesAndreas Sandberg
in the TLB Some architectures (currently only x86) require some fixing-up of physical addresses after a normal address translation. This is usually to remap devices such as the APIC, but could be used for other memory mapped devices as well. When running the CPU in a using hardware virtualization, we still need to do these address fix-ups before inserting the request into the memory system. This patch moves this patch allows that code to be used by such CPUs without doing full address translations.
2012-03-09CheckerCPU: Add function stubs to non-ARM ISA source to compile with CheckerCPUGeoffrey Blake
Making the CheckerCPU a runtime time option requires the code to be compatible with ISAs other than ARM. This patch adds the appropriate function stubs to allow compilation.
2012-01-29Implement Ali's review feedback.Gabe Black
Try to decrease indentation, and remove some redundant FullSystem checks.

2011-10-31GCC: Get everything working with gcc 4.6.1.Gabe Black
And by "everything" I mean all the quick regressions.

2011-09-19MIPS: Use inheritance to consolidate class definitions.Gabe Black
2011-09-19MIPS: Consolidate TLB related faults.Gabe Black
Pass in a bool to indicate if the fault is from a store instead of having two different classes. The classes were also misleadingly named since loads are also processed by the DTB but should return ITB faults since they aren't stores. The TLB may be returning the wrong fault in this case, but I haven't looked at it closely.
2011-09-19MIPS: Consolidate the two AddressErrorFault variants.Gabe Black
2011-09-19MIPS: Get rid of cruft in the fault classes.Gabe Black
Get rid of Fault classes left over from when this file was copied from Alpha, and rename ArithmeticOverflowFault to be IntegerOverflowFault and get rid of the old IntegerOverflowFault stub. The Integer version is what's actually in the manual, but the Arithmetic version had the implementation.
2011-09-19MIPS: Add constructors to the fault classes.Gabe Black
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help
2011-04-15includes: sort all includesNathan Binkert
2010-10-16Mem: Reclaim some request flags used by MIPS for alignment checking.Gabe Black
These flags were being used to identify what alignment a request needed, but the same information is available using the request size. This change also eliminates the isMisaligned function. If more complicated alignment checks are needed, they can be signaled using the ASI_BITS space in the flags vector like is currently done with ARM.

2009-07-21MIPS: Format the register index constants like the other ISAs.Gabe Black
Also a few more style fixes.
2009-07-21MIPS: Get MIPS_FS to compile, more style fixes.Gabe Black
Some breakage was from my BitUnion change, some was much older.
2009-07-21MIPS: Many style fixes.Gabe Black
White space, commented out code, some other minor fixes.
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
2009-04-18mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use ↵Korey Sewell
TLBS correcty in SE mode. The error was forwarding translations directly to pageTable. The TLB should check for alignment faults at bare minimum here but in the long run we should be using TLBs in SE mode for MIPS.
