| 2010-06-02 | ARM: Move the templates for predicated instructions into a separate file. | Gabe Black | |
| This allows the templates to all be available at the same time before any of the formats, etc. This breaks an artificial circular dependence. --HG-- rename : src/arch/arm/isa/formats/pred.isa => src/arch/arm/isa/templates/pred.isa | |||

| These are the only memory instructions now. | |||

| 2010-06-02 | ARM: Force the condition code for 16 bit thumb instructions to be unconditional. | Gabe Black | |
| Before, because 16 bit thumb instructions didn't set the upper 16 bits of the ExtMachInst, that field would be interpretted as "equals". | |||
| 2010-06-02 | ARM: Decode 16 bit thumb PC relative memory instructions. | Gabe Black | |

| 2010-06-02 | ARM: Make single stores decode to the new external store instructions. | Gabe Black | |
| 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. | |||

| 2010-03-23 | 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. | |||
| 2010-02-12 | O3PCU: 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. | |||
