Last Week on DirectX Shader Compiler (2017-05-02)
"A Day Late Edition"
Support for the next revision of DXIL is starting to trickle in, along with code generation improvements and a change in how htan(-inf) and htan(inf) work. DXBC didn't have a built-in intrinsic for this, and the expansion produced NaNs.
Two new SM 6.1 specifics were added last week.
The former is a set of intrinsic functions to help query vertex values and then apply appropriate weights, the latter is a new semantic value to identify views. These two aren't finalized and can't be used just yet; you'll see merges into the project with usage information when these are further along.
