ayazhafiz e52d427ac8 Hash record field name order in generated layouts ... Closes #2535 See the referenced issue for longer discussion - here's the synopsis. Consider this program ``` app "test" provides [ nums ] to "./platform" alpha = { a: 1, b: 2 } nums : List U8 nums = [ alpha.a, alpha.b, ] ``` Here's its IR: ``` procedure : `#UserApp.alpha` {I64, U8} procedure = `#UserApp.alpha` (): let `#UserApp.5` : Builtin(Int(I64)) = 1i64; let `#UserApp.6` : Builtin(Int(U8)) = 2i64; let `#UserApp.4` : Struct([Builtin(Int(I64)), Builtin(Int(U8))]) = Struct {`#UserApp.5`, `#UserApp.6`}; ret `#UserApp.4`; procedure : `#UserApp.nums` List U8 procedure = `#UserApp.nums` (): let `#UserApp.7` : Struct([Builtin(Int(I64)), Builtin(Int(U8))]) = CallByName `#UserApp.alpha`; let `#UserApp.1` : Builtin(Int(U8)) = StructAtIndex 1 `#UserApp.7`; let `#UserApp.3` : Struct([Builtin(Int(I64)), Builtin(Int(U8))]) = CallByName `#UserApp.alpha`; let `#UserApp.2` : Builtin(Int(U8)) = StructAtIndex 1 `#UserApp.3`; let `#UserApp.0` : Builtin(List(Builtin(Int(U8)))) = Array [`#UserApp.1`, `#UserApp.2`]; ret `#UserApp.0`; ``` What's happening is that we need to specialize `alpha` twice - once for the type of a narrowed to a U8, another time for the type of b narrowed to a U8. We do the specialization for alpha.b first - record fields are sorted by layout, so we generate a record of type {i64, u8}. But then we go to specialize alpha.a, but this has the same layout - {i64, u8} - so we reuse the existing one! So (at least for records), we need to include record field order associated with the sorted layout fields, so that we don't reuse monomorphizations like this incorrectly!		2022-02-21 14:10:45 -05:00
