1820802 - Add a stress test for management of wasm-gc out-of-line storage blocks

Status: RESOLVED FIXED

(Core :: JavaScript: WebAssembly, enhancement, P2)

Description

[Julian Seward [:jseward]]

What is desired is: a test case using wasm-gc structs and arrays, which
generates large numbers of such objects, spread over a range of lifetimes
(very short to relatively long). The point is to exercise the interworking of
the wasm-gc implementation and our generational GC system, in particular in
the presence of OOL storage blocks for struct and arrays.

Attachment: Bug 1820802 - Add a stress test for management of wasm-gc out-of-line storage blocks. r=rhunt.

This test case creates around one million wasm-gc arrays, spread over a range
of lifetimes (very short to relatively long). The point is to exercise the
interworking of the wasm-gc implementation and our generational GC system, in
particular in the presence of OOL storage blocks for arrays (and for structs,
although those are not used here.)
