error (spec 4.1.5, b.1.9)
track linited per local alongside the ownership state; snapshots, exit records and joins carry it, and a join keeps a local set only when every reaching path set it. x = e, a declaration initializer, &x (out-parameter), a full array initializer, or using an aggregate as an address set a local; field and element writes do not set the aggregate. while/for bodies that may run zero times do not count; do/while does. compiler, runtime, std, actor and lsp sources initialize the locals the rule flagged; zc0 accepts = {} brace lists (zeroed). tests: tests/errors/uninit_*.zc, tests/conformance/4-statements/uninit_*.zc

plain blocks
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.

Restoring undirtied lafacts when the body might free was wrong: push can
grow an array without dirtying its name, so a[99] after push warned against
a stale length 0. Keep the old lafact_keep rule; reorder explain_prover so
the constant/affine cases run before the touch() loops.
|
| |
|
|
|
|
|
|
| |
Rebased the prover WIP onto main. lafact_keep restores undirtied allocation
facts even when the loop body might free (so a later touch() no longer drops
every length fact). proven_p uses ptr_still so an outer call keeps the check.
entry_fact still supplies the size for the "might free" explain reason.
bounds_prover.zc and explain_prover.zc land with test.sh coverage.

Constant-size typed new inside o3 now calls rt.new_k instead of always
taking new_t/new_raw. new_k and recycle_leaf skip the o3 argument-fatten
path the way free/recycle already do. trees o3 new/free on the x86-64
jit dropped from about 4.1 ms to about 2.7 ms per iter (matches plain).

of p[-4]
the bnd recipe and paylen read n instead of the power-of-two block:
bnd: r6 = sub p 3; r6 = ld r6; r7 = xor p 0x2B7E1516; r6 = eq r6 r7;
r7 = sub p 4; r7 = ld r7; r7 = shr r7 32; r7 = mul r7 q;
r8 = mul i m; r8 = ltu r8 r7; r8 = xor r8 1; r0 = and r6 r8
paylen: return p[-4] >> 32
two loads instead of three; osize, bchk, release, recycle and the memdebug
leak report all read n (rt.new(4) has length 4, rt.new(0) has 0).
writers: new_raw and new_k set n; stack.h line 87 and tinyvm.ts (BigInt) set
it on stack segments. release clears n when a block goes into quarantine
(len 0, indexing traps; under memdebug bchk reports a use after free); every
free-list path (fpush, mkblock, bdrop, recycle_leaf, balloc hold) rewrites
the word as k << 16, and an array that grows gets a fresh block. a request over
2^31-1-HDR words stops in new_raw (oom), and the compiler only takes the
new_k fast path for constant sizes that fit, so n is never truncated.
bit users checked (all mask or preserve bits 32..62; none compares or copies
the whole word): gc mark and sweep; release, free, recycle, recycle_leaf;
share and own; isobj, quar, checkptr, obj_base; bclass and the bfree buddy
merge; balloc, mkblock, fpush, funlink, heap_grow; frame_grow; stack_allocate
in src/core/stack.h and src/js/tinyvm.ts; micro.c and core.c (check word
only); the compiler's two p[-4] | F_INTERNAL writes (base.zc, builtins.zc).
32-bit ports: none (baremetal, wasm and micro use int64 Cell).

(tests/test.sh line 169, examples/learn/13-memdebug.out, docs/LEARN.md,
