Ali Mohammad Pur	0e5ecef848	LibWasm: Try really hard to avoid touching the value stack ... This commit adds a register allocator, with 8 available "register" slots. In testing with various random blobs, this moves anywhere from 30% to 74% of value accesses into predefined slots, and is about a ~20% perf increase end-to-end. To actually make this usable, a few structural changes were also made: - we no longer do one instruction per interpret call - trapping is an (unlikely) exit condition - the label and frame stacks are replaced with linked lists with a huge node cache size, as we only need to touch the last element and push/pop is very frequent.	2025-08-08 12:54:06 +02:00
Ali Mohammad Pur	931b554f68	LibWasm: Give some inline capacity to the frame and label stacks ... The average wasm function rarely goes over these bounds for the labels (32 nested control structures), and 8 frames is just enough to clear most initialization code/start section without allocating anything.	2025-08-08 12:54:06 +02:00
Ali Mohammad Pur	dc67f0ad4e	LibWasm: Hold on to the stack depth for expressions in the validator ... This allows preallocating the value stack when pushing frames, avoiding repeated reallocs and copies.	2025-08-08 12:54:06 +02:00
