Connor McLaughlin 40731b49fc Bus: Handle CPU-internal narrow writes
The full 32-bits of the GPR are used.

Fixes SoundScope in the BIOS Shell.

Connor McLaughlin e087e6f3a2 CPU/Recompiler: Prevent using fastmem when cache is isolated
No point even trying since it's just going to fault.

Connor McLaughlin bf2e38aed5 CPU/Recompiler: Implement LUT-based fastmem 2020-11-24 14:49:21 +10:00
Connor McLaughlin a03bca2f72 CPU: Make fastmem a compile-time feature (support 32-bit targets) 2020-11-21 18:39:03 +10:00

Connor McLaughlin 19d6037b99 CPU: Implement instruction cache simulation
Implemented for all execution modes. Disabled by default in the cached
interpreter and recompiler, always enabled in the pure interpreter.

Connor McLaughlin 2e9f656546 CPU: Implement PGXP CPU Mode
This is *very* slow. You don't want to enable it if you don't need it.
It is also incompatible with the recompiler and will disable it if the
option is enabled.

Connor McLaughlin 1d5f810a4b CPU/Recompiler: Disable memory access exceptions by default
This means it'll no longer pass amidog's CPU test in the default config.
But no games rely on this. You can enable it in advanced options if you
want to pass the CPU test.

JIT optimizations and refactoring (#675)
* CPU/Recompiler: Use rel32 call where possible for no-args

* JitCodeBuffer: Support using preallocated buffer

* CPU/Recompiler/AArch64: Use bl instead of blr for short branches

* CPU/CodeCache: Allocate recompiler buffer in program space

This means we don't need 64-bit moves for every call out of the
recompiler.

* GTE: Don't store as u16 and load as u32

* CPU/Recompiler: Add methods to emit global load/stores

* GTE: Convert class to namespace

* CPU/Recompiler: Call GTE functions directly

* Settings: Turn into a global variable

* GPU: Replace local pointers with global

* InterruptController: Turn into a global pointer

* System: Replace local pointers with global

* Timers: Turn into a global instance

* DMA: Turn into a global instance

* SPU: Turn into a global instance

* CDROM: Turn into a global instance

* MDEC: Turn into a global instance

* Pad: Turn into a global instance

* SIO: Turn into a global instance

* CDROM: Move audio FIFO to the heap

* CPU/Recompiler: Drop ASMFunctions

No longer needed since we have code in the same 4GB window.

* CPUCodeCache: Turn class into namespace

* Bus: Local pointer -> global pointers

* CPU: Turn class into namespace

* Bus: Turn into namespace

* GTE: Store registers in CPU state struct

Allows relative addressing on ARM.

* CPU/Recompiler: Align code storage to page size

* CPU/Recompiler: Fix relative branches on A64

* HostInterface: Local references to global

* System: Turn into a namespace, move events out

* Add guard pages

* Android: Fix build
