From bd7105ff8683a680d1270eca8cd74f9002144dbd Mon Sep 17 00:00:00 2001 From: Tim Foley Date: Mon, 10 Jul 2017 15:40:42 -0700 Subject: Initial work on handling resources in structs during cross-compilation - The basic idea is that during the "lowering" pass, some types (notably: aggregate types that contain resource variables) will get turned into "tuple" types, which are pseduo-types that aren't meant to survive lowering. - An attempt to declare a variable with a tuple type expands into a tuple of declarations - An attempt to reference such a tuple-ified variable leads to a tuple of expressions - An attempt to extract a member from such a tuple expression will pick the appropriate sub-element - Dereference a tuple by dereferencing the primary expression - Expand a tuple in the argument list to a call into N arguments (by recursively flattening the tuple) - Don't create tuple types when not generating GLSL - Make sure to preserve the specialized type of a call expression through lowering, since emission of unchecked calls relies on that info. - TODO: maybe the infix/prefix/postifx/select information should come in as a side-band? Should we have modifiers on expressions? - Make sure to offset the layout for a nested field based on teh base offset of its parent variable, when generating declarations for nested fields --- source/slang/syntax.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'source/slang/syntax.cpp') diff --git a/source/slang/syntax.cpp b/source/slang/syntax.cpp index 94e0d5914..0d7a5ad74 100644 --- a/source/slang/syntax.cpp +++ b/source/slang/syntax.cpp @@ -64,7 +64,8 @@ namespace Slang #define ABSTRACT_SYNTAX_CLASS(NAME, BASE) /* empty */ #define SYNTAX_CLASS(NAME, BASE) \ void NAME::accept(NAME::Visitor* visitor, void* extra) \ - { visitor->dispatch_##NAME(this, extra); } + { visitor->dispatch_##NAME(this, extra); } \ + void* SyntaxClassBase::Impl::createFunc() { return new NAME(); } #include "expr-defs.h" #include "decl-defs.h" #include "modifier-defs.h" -- cgit v1.2.3
