macOS (Apple Silicon) support: native build running under Rosetta 2 with MoltenVK (#102)
* macos: POSIX platform layer (host fault handler, virtual memory) - hostException: Mach/POSIX signal-based host fault handler mirroring the Windows vectored handler (SIGSEGV/SIGBUS/SIGILL), behind '#elif defined(__APPLE__)'. Windows and Linux branches are untouched. - sysLinuxVirtual: mach_vm_region-based is_mapped (no /proc/self/maps on macOS), PTHREAD_MUTEX_NORMAL, and a MAP_FIXED carve-in-place allocator that never leaves an unmapped hole for dyld/Rosetta/Metal to claim. All __APPLE__-guarded; the original Linux allocator path is preserved verbatim. - sysLinuxDbg/sysLinuxFileIO: libgen.h for basename(), and a POSIX opendir/readdir implementation of SysFileGetDents (previously a stub). * macos: guest kernel backing, threads, and POSIX libs - memory/memoryAddressSpace: anonymous shm_open backing (macOS has no memfd_create) and re-reserve-on-unmap so a guest MAP_FIXED remap never destroys a host mapping (__APPLE__-guarded). Drops host <sys/mman.h> MAP_* macros so the guest's constexpr MAP_* constants compile (no-op on Windows). - pthread: undef the host PTHREAD_STACK_MIN macro; on non-Windows, pin the stack-switch asm's guest rsp/rbp to callee-saved r14/r15 (the template clobbers r12/r13); __APPLE__ no-op for the absent pthread_condattr_setclock. The Windows stack-switch asm is byte-identical. - network: define SOCKET/INVALID_SOCKET for the non-Windows paths (were undefined at 20+ use sites), and rename the non-Windows kernel_clock_* helpers to the CamelCase names the callers already use. Both repair the shared non-Windows build. Integer reinterpret_cast -> static_cast. * loader: pin stack-switch asm operands to callee-saved registers RunEntry switches to the guest stack with an asm template that clobbers r12/r13 before consuming its inputs. With plain "r" constraints the compiler may place func/guest_rsp/guest_rbp into r12/r13, so 'callq *func' jumps through the saved host rsp -- a latent miscompile on every platform that any unrelated codegen change can trigger. Pin the inputs to rbx/r14/r15, which the template never touches and the SysV callee preserves. General correctness fix (not macOS-specific); the same fix is applied to pthread RunOnGuestStack. * macos: Vulkan/MoltenVK graphics enablement - pageManager: GPU write-tracking via Mach VM queries + mprotect (mprotect cannot report the previous protection, so the expected-old check is dropped), thread id via pthread_mach_thread_np, 4 KB page-size check -- __APPLE__-guarded. - shaders/renderDraw/vulkanWindow: MoltenVK lacks VK_EXT_color_write_enable, VK_EXT_depth_clip_enable and depthBounds; fall back to static color-write masks and default depth clipping, request VK_KHR_portability_subset, and reuse the graphics queue for present when only one queue is exposed. Non-Apple pipeline/extension setup is unchanged. - window: optional borderless window (KYTY_BORDERLESS) to sidestep a Rosetta NSException in macOS window chrome. * graphics: macOS thread identity for region tracking Region-ownership locks resolve the current thread via GetCurrentThreadId() on Windows and EXIT elsewhere. Use the Mach thread port on macOS (nonzero per-thread id; 0 stays the no-owner sentinel). * macos: marshal AppKit window operations to the main thread The present worker thread shows the window, updates its icon and title, and recreates a lost Vulkan surface. AppKit traps with 'Must only be used from the main thread' when these run off the main thread. Route them through a small task queue drained by the SDL main loop (an SDL_USEREVENT wakes the loop when it is blocked in SDL_WaitEvent). Title updates are fire-and-forget; showing the window and surface recreation wait for completion. Windows and Linux call the SDL functions directly, as before. * build: ignore the _Build output directory _Build is the conventional out-of-tree build location (only _Build/vscode-clang was ignored); a stray git add could sweep build artifacts into a commit. * macos: isolate stack-switch workaround --------- Co-authored-by: nmzik <Nmzik@mail.ru>
