We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

TODO-list:
|
|
|
|
CPU common:
|
|
- Unimplemented features/bugs:
|
|
- Delay slot handling may fail sometimes (branch end of page, delay
|
|
slot next page)
|
|
- Atomical instructions
|
|
- CPU features should match real CPUs (also ASI selection)
|
|
- Optimizations/improvements:
|
|
- Condition code/branch handling like x86, also for FPU?
|
|
- Remove remaining explicit alignment checks
|
|
- Global register for regwptr, so that windowed registers can be
|
|
accessed directly
|
|
- Improve Sparc32plus addressing
|
|
- NPC/PC static optimisations (use JUMP_TB when possible)? (Is this
|
|
obsolete?)
|
|
- Synthetic instructions
|
|
- MMU model dependent on CPU model
