The C trunc
function rounds to nearest with ties toward zero. The wasm trunc
instruction rounds towards zero. The wasm nearest
instructions round to nearest with ties to even. So while it's possible there's an optimized sequence which computes the C trunc
function in wasm, it would need to be more than a single instruction.
Unless something is overlooked, all C functions which can be mapped to a single wasm function are mapped. Clang also performs this optimization inline.

Oops, I mixed up a few different things there. trunc
is already mapped; we don't use the musl version, but use this version instead.

Consequently, this is fixed!
