From 332f60c19336252d907b83882aa70665ca93a9d2 Mon Sep 17 00:00:00 2001 From: Ellie Hermaszewska Date: Fri, 12 May 2023 04:33:21 +0800 Subject: MVP for higher order functions (#2849) * MVP for higher order functions * Add shader subgroup partitioned glsl intrinsics * Implement parsing and checking for tuple types Currently there is no way to do anything useful with them from the source language however * neaten * Correct precedence of function type parsing * neaten * higher order function tests * function types of any arity * Inference for higher order functions * Add second test for unsynchronized params * regenerate vs projects * dx11 -> dx12 for saturated cooperations tests * Disable saturated cooperation tests on vulkan They fail on release builds in CI, not essential for the higher order function work however * remove saturated-cooperation tests * Remove unnecessary assert and clarify control flow in AddDeclRefOverloadCandidates * Add Tuple type name mangling * Use functype keyword to introduce function types * Add more inference tests for hof --------- Co-authored-by: Yong He --- source/slang/slang-ast-expr.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'source/slang/slang-ast-expr.h') diff --git a/source/slang/slang-ast-expr.h b/source/slang/slang-ast-expr.h index 0a875fb50..da213e8d4 100644 --- a/source/slang/slang-ast-expr.h +++ b/source/slang/slang-ast-expr.h @@ -545,6 +545,22 @@ class PointerTypeExpr : public Expr TypeExp base; }; + /// A type expression that represents a function type, e.g. (bool, int) -> float +class FuncTypeExpr : public Expr +{ + SLANG_AST_CLASS(FuncTypeExpr); + + List parameters; + TypeExp result; +}; + +class TupleTypeExpr : public Expr +{ + SLANG_AST_CLASS(TupleTypeExpr); + + List members; +}; + /// An expression that applies a generic to arguments for some, /// but not all, of its explicit parameters. /// -- cgit v1.2.3
