Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2017-12-22T00:16:23+00:00 2017-12-22T00:16:23+00:00 Tim Foley tfoley@nvidia.com 2017-12-22T00:16:23+00:00 urn:sha1:00490154ef0762839556b5884ba9b7523b265a1c Fixes #318 Most of the required support was actually in place, so this is just a bunch of fixes: - Detect when we are in "full IR" mode, so that we can always emit `struct` declarations with their mangled named (which will produce different names for different specializations, since we emit decl-refs) - Carefully exclude builtin types from this for now. We'll need a more complete solution for mapping HLSL/Slang builtin types to their GLSL equivalents soon. - Skip emitting types referenced by generic IR functions, since they might not be usable. - Also fix things up so that we emit types used in the initializer for any global variables. - Fix bug in generic specialization where we specialize the same function more than once, with different type arguments. We were crashing on a `Dictionary::Add` call where the key already exists from a previous specialization attempt. - Fix name-mangling logic so that when outputting a possibly-specialized generic it looks for the outer-most `GenericSubstitution` rather than just the first one in the list. This is to handle the way that we insert other substitutions willy-nilly in places where they realistically don't belong. :( All of these changes together allow us to pass a slightly modified (more advanced) version of the test case posted to #318.
