Expand description
An expression that is valid inside an assert_return
directive.
As of https://github.com/WebAssembly/spec/pull/1104, spec tests may include assert_return
directives that allow NaN patterns ("nan:canonical"
, "nan:arithmetic"
). Parsing an
AssertExpression
means that:
- only constant values (e.g.
i32.const 4
) are used in theassert_return
directive - the NaN patterns are allowed (they are not allowed in regular
Expression
s).
