MerryMage 52dae41d7f arm_dynarmic: Always have a 'valid' jit instance 2021-03-24 18:47:17 +00:00
bunnei a35717b245 core: arm_dynarmic: Ensure JIT state is saved/restored on page table changes. 
- We re-create the JIT here without preserving any state.

bunnei 9a4e148f9e arm: arm_dynarmic: Skip calls when JIT is invalid. 
- This can happen if called from an idle or suspension thread.

MerryMage 57c9da1b39 dynarmic: Add Unsafe_InaccurateNaN optimization 2021-01-02 20:13:21 +00:00
ReinUsesLisp b3587102d1 core/memory: Read and write page table atomically 
Squash attributes into the pointer's integer, making them an uintptr_t
pair containing 2 bits at the bottom and then the pointer. These bits
are currently unused thanks to alignment requirements.

Configure Dynarmic to mask out these bits on pointer reads.

While we are at it, remove some unused attributes carried over from
Citra.

Read/Write and other hot functions use a two step unpacking process that
is less readable to stop MSVC from emitting an extra AND instruction in
the hot path:

 mov         rdi,rcx
 shr         rdx,0Ch
 mov         r8,qword ptr [rax+8]
 mov         rax,qword ptr [r8+rdx*8]
 mov         rdx,rax
-and         al,3
 and         rdx,0FFFFFFFFFFFFFFFCh
 je          Core::Memory::Memory::Impl::Read<unsigned char>
 mov         rax,qword ptr [vaddr]
 movzx       eax,byte ptr [rdx+rax]

bunnei c10a37e5b6 hle: kernel: physical_core: Clear exclusive state after each run. 
- This is closer to pre-multicore behavior, and works a bit better.

Lioncash 5bc4eabe36 core: Eliminate remaining usages of the global system instance 
Removes all remaining usages of the global system instance. After this,
migration can begin to migrate to being constructed and managed entirely
by the various frontends.

Lioncash fc6db97a09 core: Remove usage of unicorn 
Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.

This also allows us to remove our dependency on Python.

Revert "core: Fix clang build" 2020-10-20 19:07:39 -07:00
Lioncash be1954e04c core: Fix clang build 
Recent changes to the build system that made more warnings be flagged as
errors caused building via clang to break.

Fixes #4795

Lioncash ff45c39578 General: Make use of std::nullopt where applicable 
Allows some implementations to avoid completely zeroing out the internal
buffer of the optional, and instead only set the validity byte within
the structure.

This also makes it consistent how we return empty optionals.

mode to satisfy the need for both interpreter instances.

Allows this code to compile successfully of non x86-64 architectures.
