| 2010-06-02 | ARM: Add a .w to the disassembly of 32 bit thumb instructions. | Gabe Black | |
| This isn't technically correct since the .w should only be added if there are 32 and 16 bit encodings, but always having it always is better than never having it. | |||

| 2010-06-02 | ARM: Define the store instructions from outside the decoder. | Gabe Black | |
| --HG-- rename : src/arch/arm/isa/insts/ldr.isa => src/arch/arm/isa/insts/str.isa | |||
| 2010-06-02 | ARM: Define the load instructions from outside the decoder. | Gabe Black | |
| 2010-06-02 | ARM: Implement a new set of base classes for non macro memory instructions. | Gabe Black | |
| 2010-06-02 | ARM: Create a "decoder" directory for the files implementing the decoder. | Gabe Black | |

| 2010-06-02 | ARM: Add a thumb bit bitfield. | Gabe Black | |
| 2010-06-02 | ARM: Make the predecoder handle Thumb instructions. | Gabe Black | |
| 2010-06-02 | ARM: Make sure ExtMachInst is used consistently instead of regular MachInst. | Gabe Black | |

| 2010-06-02 | ARM: Fix custom writer/reader code for non indexed operands. | Gabe Black | |
| 2010-06-02 | ARM: Remove IsControl from operands that don't imply control transfers. | Gabe Black | |
| Also remove IsInteger from CondCodes. | |||
| 2010-05-25 | x86: put back code that I accidentally deleted | Nathan Binkert | |
| 2010-05-23 | copyright: Change HP copyright on x86 code to be more friendly | Nathan Binkert | |
| 2010-05-14 | SPARC: Implement the version of movcc that uses the fp condition codes. | Gabe Black | |
| 2010-05-12 | X86: Make the cvti2f microop sign extend its integer source correctly. | Gabe Black | |
| The code was using the wrong bit as the sign bit. Other similar bits of code seem to be correct. | |||
| 2010-05-12 | X86: Actual change that fixes div. How did that happen? | Gabe Black | |
| 2010-05-03 | X86: Update the base aux vector X86 processes install. | Gabe Black | |
| 2010-05-02 | X86: Sometimes CPUID depends on ecx, so pass that in. | Gabe Black | |
| 2010-05-02 | X86: Finally fix a division corner case. | Gabe Black | |
| When doing an unsigned 64 bit division with a divisor that has its most significant bit set, the division code would spill a bit off of the end of a uint64_t trying to shift the dividend into position. This change adds code that handles that case specially by purposefully letting it spill and then going ahead assuming there was a 65th one bit. | |||
| 2010-04-15 | tick: rename Clock namespace to SimClock | Nathan Binkert | |
| 2010-03-23 | cpu: fix exec tracing memory corruption bug | Steve Reinhardt | |
| Accessing traceData (to call setAddress() and/or setData()) after initiating a timing translation was causing crashes, since a failed translation could delete the traceData object before returning. It turns out that there was never a need to access traceData after initiating the translation, as the traced data was always available earlier; this ordering was merely historical. Furthermore, traceData->setAddress() and traceData->setData() were being called both from the CPU model and the ISA definition, often redundantly. This patch standardizes all setAddress and setData calls for memory instructions to be in the CPU models and not in the ISA definition. It also moves those calls above the translation calls to eliminate the crashes. | |||
| 2010-03-10 | scons: import ply to work around scons sys.path weirdness | Nathan Binkert | |
| 2010-02-26 | cpu_models: get rid of cpu_models.py and move the stuff into SCons | Nathan Binkert | |
| 2010-02-26 | isa_parser: Make SCons import the isa_parser | Nathan Binkert | |
| this is instead of forking a new interpreter | |||
| 2010-02-26 | isa_parser: move the operand map stuff into the ISAParser class. | Nathan Binkert | |
| 2010-02-26 | isa_parser: move more support functions into the ISAParser class | Nathan Binkert | |
| 2010-02-26 | isa_parser: move more stuff into the ISAParser class | Nathan Binkert | |
| 2010-02-26 | isa_parser: move the formatMap and exportContext into the ISAParser class | Nathan Binkert | |
| 2010-02-26 | isa_parser: Make stack objects class members instead of globals | Nathan Binkert | |
| 2010-02-26 | isa_parser: add a debug variable that changes how errors are reported. | Nathan Binkert | |
| This allows us to get tracebacks in certain cases where they're more useful than our error message. | |||
