Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2019-02-05T21:55:17+00:00 2019-02-05T21:55:17+00:00 Tim Foley tfoley@nvidia.com 2019-02-05T19:53:27+00:00 urn:sha1:43950e2b2f2b1109fe25e67fc678272af6dfb7ef Before this change, code like the following would crash the compiler: ```hlsl interface IThing { /* ... */ } struct Outer { struct Inner : IThing {} } /* go on to use Outer.Inner */ ``` The problem was that the front-end logic for checking interface conformances was *only* checking declarations at the top level of a module, or nested under a generic. This change fixes the logic to recurse through the entire tree of declarations. I have added a test case that uses a nested `struct` type to satisfy an associated type requirement, to confirm that the new check works as intended.
