@pow2clk pow2clk commented Aug 5, 2020

Matrix lowering was not handling subscript oeprations when the matrix
was a shader input. copying the matrix to a temporary explicitly or
implicitly as part of a copy in function call worked around the problem.
When the argument copy was eliminated, this problem was exposed.

By adding a load for the indicated matrix for a subscript of a shader
input matrix, the lowering can procede using the lowered matrix from the
load.

Additionally, hull shaders with their uninlineable functions were
failing to detect the constanthull function as a graphics function so
the subscript lowering was being treated as if it were in a library.
Even when it got to signature lowering, there was no support for
lowering matrix loads.

The test for shaderism now tests the function attributes of the module's
entry function. The signature lowering for matrix loads is moved into a
function that is called by input lowering for both the constant hull and
entry functions.

Added general tests for matrix subscripts from different memory types as
well as specific tests for the argument passing problem in pixel and
domain shaders.

Fixes #2958

Just a note that these are just moved to subfunctions without alteration to the code.

Moving this code wasn't strictly necessary as it's still only called from here, but I moved it for consistency with the loading replacement code. I think it makes the control flow here easier to read too.

While it's ugly to add the TempLoweredMatrix argument to UserReplacer constructor, I can see how a better solution isn't readily available without some extra refactoring or something.

With an update for the couple things I've commented about, I think this is good.

Let's add extra run line(s) to try lib target (like lib_6_3), and put [shader("pixel")] in front of entry point. Same with other tests as it makes sense.

@pow2clk
broaden detection of signature entries
5e863b8 
A more correct way to identify functions that should delay the lowering
of their matrix parameters to signature lowering time is to query
whether the function has a signature. This covers entry functions for
graphics shaders and also constant patch functions.

Adds library variants to existing tests as well
