Wrong opcode for v8x16.shuffle?

[libwasm]

The proposal document describes the opcode for v8x16.shuffle as 0xfd 0xc1,

The wabt tools however use the code 0xfd 0x03.

Which one is rightt?

You should use 0x03, since that's the opcode used by most tools and engines. At some point the shuffle opcode got updated in the spec, but there was not a critical mass of implementations that switched to using the new opcode. Note that we are planning a larger renumbering to happen soon in WebAssembly/simd#209, and at that point the entire ecosystem will have a coordinated update.

Thanks, I will do that,
