WalkthroughThe change enables split portal execution for unknown-length unpacking, adds runner wiring, preserves source-driver and portal-frame identity, records portal trace events, carries explicit blackhole transitions, initializes greenfield state, and keeps non-portal frame residual calls. ChangesPortal splitting and runner wiring
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The changes can misinitialize JIT state, retain incorrect callee instruction state, and break a downstream consumer at compile time. These issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

This manually moves the loop into a new interpreter function and routes the original through a global hook, even though the corresponding upstream operation is a translation-time transformation performed by WarmRunnerDesc.split_graph_and_record_jitdriver and WarmRunnerDesc.rewrite_jit_merge_point. Consequently the interpreter source no longer remains a line-by-line port, and every future change to _unpackiterable_unknown_length must be duplicated between the prologue and synthetic portal. Configure the newly supported autoreds graph split against the original function and implement the runner rewrite in the translation pipeline rather than embedding the generated graph shape in pyre-interpreter.

When a trace is active for cell A and an interpreted callback reaches an uncompiled cell B, this per-cell check now falls through. maybe_compile_and_run_step then ticks and resets B's counter when it returns StartTracing, but JitDriver::bound_reached immediately returns because the shared MetaInterp is still tracing A; it also reaches the global counter-decay path before that refusal. Thus callbacks or generator loops encountered during long jd0/jd1 traces can repeatedly lose hotness without ever starting a trace. Compiled-token entry can remain per-cell, but the trace-start/counter path needs the global gate until nested portals have independent MetaInterp sessions.

Enable warmspot portal split by default. Register unpackiterable_portal as jd1 and return portal_runner from the original unpack. maybe_compile_and_run reads JC_TRACING on the cell, not the driver. Abort unwind consumes SwitchToBlackhole. Autoreds portals split after autodetect. Non-portal frame loads keep their receiver. Assisted-by: Claude

When this entry is used with a driver that has both greens and a virtualizable, such as jd0's three greens plus frame/ec, live still contains every original_boxes element. However, MetaInterp::initialize_virtualizable explicitly treats its argument as reds-only and prepends num_green_args placeholders, so passing &live double-counts the greens: its reconstructed lookup at num_green_args + index_of_virtualizable lands on the first green rather than the frame red, and subsequent vable/input-layout calculations are correspondingly shifted. Pass only the red suffix here or add a full-original-boxes variant matching upstream MetaInterp.initialize_state_from_start.

Treat TraceAction::SwitchToBlackhole as a public API break. TraceAction is a public exhaustive enum in the publishable majit-* crates, and an out-of-tree path-patched consumer uses it. Its exhaustive matches can now fail to compile. Update those matches and document the breaking release; #[non_exhaustive] would not preserve existing exhaustive matches.

Pass only red values to initialize_virtualizable.
original_boxes uses the greens ++ reds portal layout. initialize_virtualizable requires reds-only and prepends green placeholders before applying num_green_args + index_of_virtualizable. This duplicates the green offset and can read the wrong virtualizable data or panic at original_boxes[index].

Key PYRE_PORTAL_SPLIT by its resolved boolean.
portal_split_enabled() sends unset, 1, and on through the same split_portal: true path. However, codegen_cache_key() hashes the raw value from LOWERING_GATE_ENV, so these spellings can create separate entries. The bounded shared cache retains 96 entries by last use, so equivalent entries can consume slots, evict useful entries, and trigger prepass regeneration. Hash the canonical true/false result instead, and update the adjacent comment to match.

Publish last_instr for non-portal callee frames.
emit_new_pyframe_inline_with_params creates the callee frame, and the inline-call path seeds frame_var with that frame. The ReturnValue comment that non-portal frame_var aliases the outermost frame is stale. Gate the last_instr store on frame_inputs.has_frame() instead of is_true_portal, and update the comment.

In `@pyre/pyre-jit/src/jit/codewriter.rs` around lines 9517 - 9519, Update
emit_new_pyframe_inline_with_params and the surrounding ReturnValue handling so
the last_instr store is gated by frame_inputs.has_frame() rather than
is_true_portal. Revise the stale comment to state that non-portal callee
frame_var refers to the callee frame created for the inline call.
