Topic: wasmtime / issue #6698 Cranelift: Cannot create 128 bit c...

Wasmtime GitHub notifications bot (Jul 06 2023 at 19:00):

Kixiron labeled issue #6698:

I can't figure out how to create a 128bit constant. My closest attempt was by creating a 128bit vector which I then bitcast into an i128, but that doesn't work

let constant = builder.func.dfg.constants.insert(V128Imm::from(value).into());
let vector = builder.ins().vconst(types::I64X2, constant);

let mut flags = MemFlags::new();
flags.set_endianness(if cfg!(target_endian = "little") {
    Endianness::Little
} else {
    Endianness::Big
});

builder.ins().bitcast(types::I128, flags, vector)

Kixiron labeled issue #6698:

I can't figure out how to create a 128bit constant. My closest attempt was by creating a 128bit vector which I then bitcast into an i128, but that doesn't work

let constant = builder.func.dfg.constants.insert(V128Imm::from(value).into());
let vector = builder.ins().vconst(types::I64X2, constant);

let mut flags = MemFlags::new();
flags.set_endianness(if cfg!(target_endian = "little") {
    Endianness::Little
} else {
    Endianness::Big
});

builder.ins().bitcast(types::I128, flags, vector)

Cranelift panics with this

I can't figure out how to create a 128bit constant. My closest attempt was by creating a 128bit vector which I then bitcast into an i128, but that doesn't work

let constant = builder.func.dfg.constants.insert(V128Imm::from(value).into());
let vector = builder.ins().vconst(types::I64X2, constant);

let mut flags = MemFlags::new();
// Endianness is required here since I'm "changing the number of lanes" so this is my best guess for getting correct behavior?
flags.set_endianness(if cfg!(target_endian = "little") {
    Endianness::Little
} else {
    Endianness::Big
});

builder.ins().bitcast(types::I128, flags, vector)

Yeah, 128-bit constants are currently awkward in Cranelift. Usually we build them out of smaller constants. If the value fits within a 64-bit constant then you can use iconst.i64 followed by uextend (or sextend if you want to sign-extend). Otherwise you can build the two 64-bit halves with iconst.i64 and then combine them with iconcat. There are examples in cranelift/filetests/filetests/runtests/i128-*.clif.

Hey,

The best way to do that operation currently is to either use a iconcat to merge two iconst.i64's, or use sextend/uextend if your constant can fit in a i64.

See also isplit if you end up needing to separate it out again for whatever reason.

Bitcasting a 128bit vector into a i128 should work, but in practice it's not implemented in any backend (CC: #6104)

Hopefully this was all you needed, so I'm going to close this issue. But please re-open it if we missed something!

Ideally we'd either have better documentation explaining this, or we'd remove the weird special case around i128 constants. If anyone runs into this problem, finds this discussion, and wants to try to tackle either of those solutions, let's chat! Otherwise I don't know when either alternative will happen :sweat_smile:
