Add complete ARM64 Windows (AArch64 WoA) support to SBCL. This enables building and running SBCL natively on Windows 11 ARM devices. Key design decisions: - x18 register reserved as TEB pointer (Windows ARM64 ABI requirement), matching the existing Darwin reservation - Safepoint GC with fake_foreign_function_call to save register context for precise stack scanning (ARM64 uses separate C and control stacks) - VEH (Vectored Exception Handling) for ARM64, decoding BRK instructions which Windows reports as EXCEPTION_ILLEGAL_INSTRUCTION - sb_udivmodti4 takes hi/lo split arguments to avoid __uint128_t ABI issues on LLP64 where unsigned long is 32 bits - FP exception traps disabled (ARM64 Windows does not deliver FP exceptions even with FPCR trap bits set) - Dynamic space pages committed on demand (Windows reserves but does not commit the full dynamic space upfront) New files: - src/runtime/Config.arm64-win32: Build configuration - src/runtime/arm64-win32-os.c: OS layer (VEH, context access, FP) - src/runtime/arm64-win32-os.h: Platform header - .github/workflows/windows-arm64.yml: CI workflow Modified files grouped by subsystem: Runtime (ARM64-specific): - arm64-arch.c: Windows memory APIs, LLP64-safe pointer storage, sb_udivmodti4 split-argument ABI, static space NIL header guard - arm64-assem.S: Windows calling conventions for call_into_lisp and call_into_c, TlsGetValue for thread pointer, x18 reservation Runtime (Windows general): - win32-os.c: ARM64 safepoint page handling, BRK exception decode, ARM64 VEH, dynamic space page commit, ARM64 debug printing Compiler: - vm.lisp: Reserve x18 on Windows (matching Darwin) - c-call.lisp: Don't zero control-stack-pointer on Windows (not FFCA) - parms.lisp: Address space layout for Windows ARM64 - tramps.lisp: Save CSP to thread for GC, don't zero CSP on Windows - genesis.lisp: GC_SAFEPOINT_PAGE_ADDR for non-x86-64 platforms - parms.lisp (generic): Update safepoint space comment - debug-int.lisp: NFP handling for ARM64 Windows - float-trap.lisp: Disable FP traps on ARM64 Windows - coreparse.c: ARM64 guard for TEXT_SPACE_START assignment Build system: - make-config.sh: ARM64 Windows detection and feature flags - make-windows-installer.sh: ARM64 architecture in installer CI: - linux-arm64.yml, mac.yml: Robustness fixes for repo naming - windows-arm64.yml: New workflow for ARM64 Windows builds Tests: - subr.sh: Auto-detect sbcl.exe on Windows Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
