16B ldp/stp are atomic on v8.4a+. See Arm Architecture Reference Manual,
"Changes to single-copy atomicity in Armv8.4". Add load/release atomic
impls for this instruction and add detection for 8.4a+ capability.
* Ensure ::PtrSame<T, Derived> is true.
* Allow id_base, id_step and id_count to be of enumeration type.
* Fix potential deadlock in kernel explorer.
idm::select:
* Allow to select multiple inherited object types for idm::select.
* Allow function reference types. (they don't allow access to operator() directly, use deducing std::function constructor instead)
* Ensure ::is_same_ptr<T, object_type> is true.
* BufferUtils: use naive function pointer on Apple arm64
Use naive function pointer on Apple arm64 because ASLR breaks asmjit.
See BufferUtils.cpp comment for explanation on why this happens and how
to fix if you want to use asmjit.
* build-macos: fix source maps for Mac
Tell Qt not to strip debug symbols when we're in debug or relwithdebinfo
modes.
* LLVM PPU: fix aarch64 on macOS
Force MachO on macOS to fix LLVM being unable to patch relocations
during codegen. Adds Aarch64 NEON intrinsics for x86 intrinsics used by
PPUTranslator/Recompiler.
* virtual memory: use 16k pages on aarch64 macOS
Temporary hack to get things working by using 16k pages instead of 4k
pages in VM emulation.
* PPU/SPU: fix NEON intrinsics and compilation for arm64 macOS
Fixes some intrinsics usage and patches usages of asmjit to properly
emit absolute jmps so ASLR doesn't cause out of bounds rel jumps. Also
patches the SPU recompiler to properly work on arm64 by telling LLVM to
target arm64.
* virtual memory: fix W^X toggles on macOS aarch64
Fixes W^X on macOS aarch64 by setting all JIT mmap'd regions to default
to RW mode. For both SPU and PPU execution threads, when initialization
finishes we toggle to RX mode. This exploits Apple's per-thread setting
for RW/RX to let us be technically compliant with the OS's W^X
enforcement while not needing to actually separate the memory
allocated for code/data.
* PPU: implement aarch64 specific functions
Implements ppu_gateway for arm64 and patches LLVM initialization to use
the correct triple. Adds some fixes for macOS W^X JIT restrictions when
entering/exiting JITed code.
* PPU: Mark rpcs3 calls as non-tail
Strictly speaking, rpcs3 JIT -> C++ calls are not tail calls. If you
call a function inside e.g. an L2 syscall, it will clobber LR on arm64
and subtly break returns in emulated code. Only JIT -> JIT "calls"
should be tail.
* macOS/arm64: compatibility fixes
* vm: patch virtual memory for arm64 macOS
Tag mmap calls with MAP_JIT to allow W^X on macOS. Fix mmap calls to
existing mmap'd addresses that were tagged with MAP_JIT on macOS. Fix
memory unmapping on 16K page machines with a hack to mark "unmapped"
pages as RW.
* PPU: remove wrong comment
* PPU: fix a merge regression
* vm: remove 16k page hacks
* PPU: formatting fixes
* PPU: fix arm64 null function assembly
* ppu: clean up arch-specific instructions
Implements the basic functionality of cellMusicDecode.
Works with Space Invaders (if you add the list selection from the other PR).
Probably fixes SSX custom music.
Fixes listing BGM in Gundam.
The returned content was always empty.
Playback of the tracks will still require a MusicSelectionContext and cellMusic playback, which isn't implemented yet.
Notably, runtime-built SSSE3 version of VPERM.
Some other instructions are refactored and vectorized.
Aarch64 impl of multiple instructions including VPERM.
* Update asmjit dependency (aarch64 branch)
* Disable USE_DISCORD_RPC by default
* Dump some JIT objects in rpcs3 cache dir
* Add SIGILL handler for all platforms
* Fix resetting zeroing denormals in thread pool
* Refactor most v128:: utils into global gv_** functions
* Refactor PPU interpreter (incomplete), remove "precise"
* - Instruction specializations with multiple accuracy flags
* - Adjust calling convention for speed
* - Removed precise/fast setting, replaced with static
* - Started refactoring interpreters for building at runtime JIT
* (I got tired of poor compiler optimizations)
* - Expose some accuracy settings (SAT, NJ, VNAN, FPCC)
* - Add exec_bytes PPU thread variable (akin to cycle count)
* PPU LLVM: fix VCTUXS+VCTSXS instruction NaN results
* SPU interpreter: remove "precise" for now (extremely non-portable)
* - As with PPU, settings changed to static/dynamic for interpreters.
* - Precise options will be implemented later
* Fix termination after fatal error dialog
- Try to use REP MOVSB when the size of the transfer is above a certain threshold
- This threshold is determined by the ERMS and FSRM cpuid flags
- The threshold values are (roughly) taken from GLIBC
- A threshold of 0xFFFFFFFF indicates that the cpu has neither flag
- Also detect the new RTM_ALWAYS_ABORT bit in cpuid
- This new bit indicates that RTM is disabled in the microcode
- On cpus with RTM_ALWAYS_ABORT TSX can be renabled by writing 0x4 to the msr 0x0000010F
shm_open() returns a file descriptor on success, not zero. As SHM_ANON
only exists on FreeBSD which also has memfd_create use the same code
as on Linux.

Arguments should be provided via fmt::tie() due to some limitations.
Allow to specify simple message (non-formatting) for plain ::ensure().
Remove redundant function for narrow error.
This lifts the limitation for casting with abstract classes.
Use new C++20 feature (constexpr allocator) to test viability.
Add SamePtr concept to types.hpp
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.
Fix operators == and <=> for synthesized rel-ops.
