Move the temp allocation back to hlsl_codegen.c.
Note that the DCL_TEMPS instructions wouldn't be necessary if we had the
capacity to store the temp_count for both the main program and the patch
constant program (or more generally speaking, a temp_count for all
phases).
The plan is to eventually also move the HS_CONTROL_POINT and
HS_FORK_PHASE markers to the vsir_program, making it able to contain
both functions.
This node type will be deleted (again) once the hlsl->vsir->tpf
translation is complete. It serves the purpose of allowing to keep
both real hlsl_ir_nodes and vsir_instructions in the hlsl_block,
until all the former can be translated into the latter.
This is required to properly optimize signatures, because these
semantics must be alligned while being packed:
- Array elements.
- The first fields of structs.
- Major vectors of a matrix.
For now this has no effect since semantics are allocated with reg_size
4, but will have effect when optimizing interstage signatures.
The generated pixel shader input signature must be consistent with the
generated vertex shader output signature for the same data type.
Since the interpolation mode affects allocation order, the allocator
needs to know the modifiers for both input and output signature elements.
Similarly to the already done split from
HLSL IR -> d3dbc
to
HLSL IR -> vsir -> d3bc
we now start splitting the
HLSL IR -> tpf
translation into
HLSL IR -> vsir -> tpf
So hlsl_sm4_write is split into two functions, sm4_generate_vsir() and
tpf_compile().
This translation should be completed once tpf_compile() no longer needs
the hlsl_ctx and entry_func parameters.
