Module host_fns

Enums§

clear_gc_test_hook: Clear the GC test hook.
clear_stack_map_registry: Clear the stack map registry for the current thread.
gc_trigger: GC trigger: called by JIT code when alloc_ptr exceeds alloc_limit.
gc_trigger_call_count: Get gc_trigger call count. Only call from tests.
gc_trigger_last_vmctx: Get last vmctx passed to gc_trigger. Only call from tests.
heap_alloc: Heap allocation: called by JIT code for large or slow-path allocations.
heap_force: Force a thunk to WHNF.
host_fn_symbols: Return the list of host function symbols for JIT registration.
last_gc_roots: Get collected roots from the last gc_trigger call.
reset_test_counters: Reset test counters. Only call from tests.
runtime_error: Called by JIT code for runtime errors (divZeroError, overflowError). Sets a thread-local error flag and returns null. The effect machine checks this after JIT returns and converts to Yield::Error. kind: 0 = divZeroError, 1 = overflowError
set_gc_test_hook: Set a hook to be called during gc_trigger with the collected roots.
set_stack_map_registry: Set the stack map registry for the current thread.
take_runtime_error: Check and take any pending runtime error from JIT code.
unresolved_var_trap: Called by JIT code when an unresolved external variable is forced. Returns null to allow execution to continue (will likely segfault later). In debug mode (TIDEPOOL_TRACE), logs and returns null.
