Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2017-11-08T00:47:36+00:00 2017-11-08T00:47:36+00:00 Tim Foley tfoleyNV@users.noreply.github.com 2017-11-08T00:47:36+00:00 urn:sha1:a5dfa5cd2bfa11fb3d9e84877f8dead1815e9077 - Add definition of `discard` instruction - A `discard` is a terminator instruction, just like `returnVoid` - Lower `DiscardStmt` in AST to a `discard` instruction in the IR - Emit `discard` instruction as a `discard;` statement when emitting HLSL/GLSL - Add a test case using the "graphics compute" mode that tests discard. The test writes to one entry in a UAV before doing a conditional (always true at runtime) discard, and then writes to another entry; we expect to see the results of the first write, but not the second.
