amiberry-jit-fix
by BlitterStudio
ARM64 JIT compiler fixes for Amiberry (GitHub issue #1766). This skill captures the complete technical knowledge from 20+ debugging sessions that identified and fixed: (a) a page 0 DMA corruption crash during A1200 Kickstart boot, (b) visual corruption (black gadgets, garbled text) caused by incorrect inter-block flag optimization, (c) SIGSEGV crashes on unmapped natmem gaps (e.g., 0x00F10000) in complex configs with hardfiles/RTG, and (d) BSR.L/Bcc.L backward branch crashes from 32-bit displacement zero-extension on 64-bit platforms. Use this skill when working on: (1) the JIT_DEBUG_MEM_CORRUPTION code in compemu_support_arm.cpp or newcpu.cpp, (2) the page 0 DMA guard mechanism (mprotect/SIGSEGV/BRK single-step), (3) any ARM64 JIT register width bugs (64-bit vs 32-bit instruction selection), (4) any crash or exception cascade during A1200 boot with JIT enabled, (5) 68040 JIT mode issues on ARM64, (6) the inter-block flag optimization bug and its fix (dont_care_flags at block boundaries), (7) natmem gap crashes and the commit_natmem_gaps() fix in amiberry_mem.cpp. MANDATORY TRIGGERS: JIT crash, page 0, DMA guard, vec2, exception vector corruption, blitter DMA, mprotect, SIGSEGV handler, BRK single-step, ARM64 JIT, Kickstart boot, visual corruption, black gadgets, garbled ROM version, compemu_support_arm, JIT_DEBUG_MEM_CORRUPTION, inter-block flag, dont_care_flags, 68040 JIT, natmem gap, unmapped region, commit_natmem_gaps, 0x00F10000, canbang, PROT_NONE, BSR, Bcc, branch displacement, sign extension, comp_pc_p, comp_get_ilong, 64-bit pointer, zero-extend, backward branch, gencomp_arm.
