 R_ADDRARM64 relocations).  Like the other encoders it is validated
 byte-for-byte against `GOARCH=arm64 go tool asm`.

+On top of the per-architecture encoders, every framed function carries the
+**stack-split guard**: the prologue check against `g.stackguard0` (small,
+medium and large frame classes, the medium and large classes materialising
+their offset through the architecture's temporary register and the large
+class adding the SP-underflow branch) and the trailing morestack block
+(save the link register, `CALL runtime.morestack_noctxt`, jump back to the
+function entry).  The auto-NOSPLIT rule, the frame classes, the large-frame
+prologue and epilogue forms and the tail calls match the toolchain's
+`stacksplit` and `preprocess` output byte for byte; a parity suite
+assembles kernel files with gasm and the installed `go tool asm` and diffs
+the bytes on all four architectures.

 On top of the encoder, `Assemble` walks a parsed `TEXT` body, converts each
 operand to an encoder operand, and lays the instructions out so local labels
 resolve to relative jump offsets: jumps start in the short (rel8) form and
