Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2017-07-24T01:37:52+00:00 2017-07-24T01:37:52+00:00 Tim Foley tfoley@nvidia.com 2017-07-24T01:22:30+00:00 urn:sha1:d4cfe5781284551d7c5ccf2cf1d28a86211bb1df The basic bug there is that if you have a member of `struct` type in a `uniform` block and then pass a reference to that member directly to a call: ``` struct Foo { vec4 bar; }; uniform U { Foo foo; }; void main() { doSomething(foo); } ``` then glslang generates invalid SPIR-V which seems to cause an issue for some drivers. This change works around the problem by detecting cases where an argument to a function call is a reference to `uniform` block member (of `struct` type) and then rewrites the code to move that value to a temporary before the call.
