rt.MW is the end of the fixed map (PW) since the growing heap landed; the
heap starts right there, so ld16(addr_b(rt.MW)-1) read the heap's first
byte: 0 on the default map by luck, 0x40 on the small map (16384).
Probe the real byte-op bound instead: core answers syscall(9,10) with the
host reservation MW; micro ports, whose bound is their memory size, fall
back to syscall(9,0).

a call to rt.new_k / rt.recycle_leaf with a constant class, or to rt.own,
does its class-list pop or push (or owner store) inline and goes on after
the call; an empty list, memdebug, a held range, a block outside memory, a
translated word or a type/class mismatch takes the ordinary call. in a
region this replaces the o3_invoke round trip. o3 frees of leaf objects now
use recycle_leaf too (new_k stamps the type inside o3 since b86db60).
ZYNOFASTALLOC=1 turns it off; ZYPERFMAP=1 writes a perf map of translated code.
tests/programs/o3_freelist.zc: reuse, zeroing, an empty list, untyped
neighbours, memdebug; jit vs ZYNOFASTALLOC vs ZYO3INTERP.
find_replace: cover o3 function prologues on every backend2026-10-15T02:45:36+00:00zinczinc@downsta.ir2026-10-15T02:45:36+00:00urn:sha1:1db57f77e9c627bc9c00f9e2f827aa72b425b739
arm64, llvm and the region-interpreter rdrop path now watch the two
prologue words the way the x86-64 jit already did, so icon.replace_function's
lit+jmp patch retires a compiled callee (and clears fn_nat) instead of leaving
a stale stub. three new icon regressions: repeated o3 replace, failed
publication keeps the old entry, and a direct call after warming the region.
x86-64 o3: direct o3-to-o3 calls (rcall_x64 / rfinish_x64)2026-10-15T01:41:59+00:00zinczinc@downsta.ir2026-10-15T01:41:59+00:00urn:sha1:c3156f6a910581c7ca98ffa08470d1f81e21bdde
Port arm64's rcall/rfinish to the x86-64 region jit: call the callee's entry
stub through fn_nat with a built frame, return via linkstk, and fall back to
o3_invoke when the stub is missing or the frame/depth check fails. Clear
fn_nat on rforget and cover the function prologue so icon.replace_function
drops the region (o3_caller_replace). vm_until saves jit_depth around nested
bytecode, matching arm64.
bounds: body scan, loop-entry hoisting, pointer proofs from requested size, --explain-checks v1 (non-o3 code)2026-10-14T16:33:38+00:00zinczinc@downsta.ir2026-10-14T14:52:04+00:00urn:sha1:459b7661aaa0d65d01be064bd4b9976c4f045a5c
