  v0.31.0 Stable

  The arm64 encoder (Phase 5 — complete) ships with ELF64 and GOOBJ emission,
  verified byte-for-byte against GOARCH=arm64 go tool asm and linked into a
  real go build. The encoder covers the full integer instruction set, FP
  arithmetic, conditional select, CRC32, and the MOV pseudo-instruction with
  bitmask immediate encoding. The project now requires Go 1.27.

  Added

  • arm64 encoder (Phase 5 — complete). gasm asm can now assemble _arm64.s
    files: the AArch64 integer instruction set with the MOV pseudo-instruction and
    its immediate-constant expansions (MOVZ/MOVN/MOVK for wide immediates, ORR with
    logical bitmask encoding for values like $1), data-processing (shifted
    register and immediate forms), load/store (scaled unsigned and unscaled9-bit
    immediate), conditional and unconditional branches, FP/SP frame mapping,
    SB/global symbol references (ADRP+ADD pairs with R_ADDRARM64 relocations),
    jump chain folding, and ELF64 emission (gasm asm --format elf). Ground-truth
    verification against GOARCH=arm64 go tool asm matches byte-for-byte. Phase 5
    (the other architectures — RISC-V, LoongArch, arm64) is now complete.

  Changed

  • Go 1.27 required. The project now requires Go 1.27 (toolchain go1.27.0).
    The R_DWTXTADDR_U4 relocation type is detected at runtime for backward
    compatibility.
