[spv-in] sampling from depth textures returns a scalar and is splatted (#6384) 2024-10-11 20:24:16 +02:00

0f17ad6455 [naga] Add new function, GuardedIndex::from_expression. 
Pull out the code to build a `naga::proc::index::GuardedIndex` from a
`Handle<Expression>` into its own function,
`GuardedIndex::from_expression`. Use that function in
`GuardedIndex::try_resolve_to_constant`.

3d85781f05 [naga spv-out] Consolidate code to find index values. 
Let the SPIR-V backend use `GuardedIndex::try_resolve_to_constant`,
rather than writing out its definition in `write_restricted_index` and
`write_index_comparison`.

Call `try_resolve_to_constant` in one place, in `write_bounds_check`,
and simply pass the `GuardedIndex` into subroutines.

Reduce `write_restricted_index` and `write_index_comparison` to case
analysis and code generation.

Note that this commit does have a benign effect on SPIR-V snapshot
output for programs like this:

    let one_i = 1i;
    var vec0 = vec3<i32>();
    vec0[one_i] = 1;

The value indexing `vec0` here is an `i32`, but after this commit, the
operand to `OpAccessChain` becomes a `u32` constant (with the same
value).

This is because `write_bounds_check` now calls
`try_resolve_to_constant` itself, rather than deferring this work to
its callees, so it may return `BoundsCheckResult::KnownInBounds` even
when the `Unchecked` policy is in force. This directs the caller,
`write_expression_pointer`, to treat the `OpAccessChain` operand as a
fresh `u32` constant, rather than simply passing through the original
`i32` expression.

ca729cc607 Introduce HashableLiteral 
The only reason `Literal` had to implement `Eq` and `Hash` was due to the SPV backend having to cache those in a `HashMap`.

The `PartialEq` impl was error prone due to the match not being exhaustive.
