Parser implementations: - dataSection: parse segments, evaluate i32.const offset expressions, copy data bytes into linear memory - globalSection: parse globals with init expression evaluation and type/mutability handling - memorySection: parse memory limits (initial/max pages, flags) - startSection: parse start function index - wasm.parser: route new section types to their handlers VM opcode implementations: - Control: nop, unreachable (trap), drop, select, return - Variables: local.get/set/tee, global.get/set - Constants: i32.const, i64.const, f32.const, f64.const - I32 arithmetic: add, sub, mul, div_s, div_u, rem_s, rem_u, clz, ctz, popcnt - I32 bitwise: and, or, xor, shl, shr_s, shr_u, rotl, rotr - I32 comparison: eqz, eq, ne, lt_s/u, gt_s/u, le_s/u, ge_s/u - I64 arithmetic: add, sub, mul, div_s, div_u, rem_s, rem_u, clz, ctz, popcnt - I64 bitwise: and, or, xor, shl, shr_s, shr_u, rotl, rotr - I64 comparison: eqz, eq, ne, lt_s/u, gt_s/u, le_s/u, ge_s/u - F32/F64 comparison: eq, ne, lt, gt, le, ge - Memory loads: i32/i64/f32/f64.load, i32.load8_s/u, i32.load16_s/u, i64.load8_s/u, i64.load16_s/u, i64.load32_s/u - Memory stores: i32/i64/f32/f64.store, i32.store8, i32.store16, i64.store8, i64.store16, i64.store32 - Memory management: memory.size, memory.grow Bug fixes: - memory.grow: guard against uint32 underflow when growing 0 pages - select: fix off-by-one stack indexing for val1/val2 - i32/i64.shr_s: use manual arithmetic shift right (logical shift + sign-bit mask fill) instead of RTL intrinsics for bare-metal kernel compatibility Type additions: - wasm.types: new records and pointer types for globals, locals, and section structures
