Listing 6.31. Diagnostic output from fxc. exe.
The first section ("Buffer Definitions:") is a listing of all constant buffers used in
the shader program. This includes the offset and size of each individual constant, as well
as whether or not the constant is actually used in the shader program. The next section
("Resource Bindings:") contains the name, type, and slot of all resource objects and con-
stant buffers used in the shader. The third section ("Input signature:") contains a listing of
all inputs required by the shader program. The input signature can be very important when
matching shaders for one stage with shaders from another stage, since the earlier shader
must produce enough outputs to satisfy the input signature. This is also true of vertex shad-
ers, except now the bound vertex buffer and. corresponding input layout must provide the
elements required by the input signature. The final section ("Output signature:") simply
