* 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
* 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
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.
cmp_rdata and mov_rdata are using __attribute__((always_inline)),
without inline, that is not supported on current g++ (see RPCS3#1546).
Moreover __attribute__((always_inline)) is a noop if used without inline so
just remove it.
A proper fix is to move the 2 functions in an header file as static
(with FORCE_INLINE) so it can be correctly inlined by the compiler.
* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
Add atomic_t<>::observe() (relaxed load)
Add atomic_fence_XXX() (barrier functions)
Get rid of MFENCE instruction, replace with no-op LOCK OR on stack.
Remove <atomic> dependence from stdafx.h and relevant headers.
These conversions don't exist in std::shared_ptr-alike types.
But I don't want to bother with == operators until we have proper C++20.
Removed trivial conversion for atomic_ptr because it's heavyweight.
* SPU Debugger: Fix try_get_insert_mask_info
* Debugger: Always update thread state on context's data change
No longer needing to press on thread's instructions for actions to work!
Move bits to the highest, set RWX order.
Use only one reserved value (W = locked).
Assume lock size 128 for range_locked.
Add new "Size" template argument that replaces normal argument.
Fix logic error in callstacks handling code, always set first to false after first iteration.
Add explicit check for zero return addresses. Current code validity checks may not check for it properly when it sits on interrupt handler entry point (which may contain valid code).
Do not allow 0x3FFF0 to be a back chain address because it needs space for LR save area, only 0x3FFE0 and below satisfy this criteria.
Reduced static memory amount for waitable atomics.
Allow notifier to skip notifications if wait/notify masks don't overlap.
Improve raw_notify to wake up the thread by its id, add thread_id arg.
Add optional mask argument to notify_one() and notify_all().
