To simplify SM 6 support, insert a control point id relative address where needed, and declare control point phase inputs where missing.
From: Conor McCarthy cmccarthy@codeweavers.com
In SPIR-V the address must include the invocation id, but in TPF it is implicit. Move the register index up one slot and insert an OUTPOINTID relative address. --- libs/vkd3d-shader/ir.c | 87 ++++++++++++++++++++++++ libs/vkd3d-shader/spirv.c | 32 ++------- libs/vkd3d-shader/vkd3d_shader_private.h | 3 + 3 files changed, 97 insertions(+), 25 deletions(-)

The SPIR-V backend will emit a default control point phase. Inserting inputs into the IR allows handling of declarations via the usual path instead of an ad hoc implementation which may not match later changes to input handling. --- libs/vkd3d-shader/ir.c | 101 ++++++++++++- libs/vkd3d-shader/spirv.c | 178 +++-------------------- libs/vkd3d-shader/vkd3d_shader_private.h | 11 +- 3 files changed, 127 insertions(+), 163 deletions(-)

Overall, I think this is great; the special handling for hull shaders in the SPIR-V backend has really been a pain, and getting rid of it will be a nice simplification. Two notes though:

It doesn't need to be in this series, but I think we have a couple of other places where we could use this helper as well. In particular in shader_instruction_eliminate_phase_instance_id() and a few places in d3dbc.c.
+static void shader_dst_param_normalise_outpointid(struct vkd3d_shader_dst_param *dst_param, + struct vkd3d_shader_normaliser *normaliser) +{ + struct vkd3d_shader_register *reg = &dst_param->reg; + + if (normaliser_is_in_control_point_phase(normaliser) && reg->type == VKD3DSPR_OUTPUT) + { + assert(reg->idx[1].offset == ~0u); + reg->idx[1] = reg->idx[0]; + /* The control point id param is implicit here. Avoid later complications by inserting it. */ + reg->idx[0].offset = 0; + reg->idx[0].rel_addr = normaliser->outpointid_param; + } +}
I don't think we should use assert() above, unless we first reject shaders containing these in the parser. I.e., as-is it would be possible to craft a shader that triggers an assert in vkd3d-shader, and applications using vkd3d-shader. That's undesirable because input shaders are potentially outside the control of the application, depending on the use-case.

`normaliser_is_in_fork_or_join_phase(normaliser)` is always `false`, because as soon as you see a fork or join phase you return, isn't it?
More in general, it seems that the logic of this loop is more complicated than it could be, unless I am missing something. It seems that you want to invoke `shader_normaliser_emit_hs_input()` the first time you see a fork or join phase, provided that you didn't see a control point phase. To do that it is enough to return as soon as you see a control point phase and call that function as soon as you see a fork or join phase (and then return). You don't need to track the phase or whether you've already seen a control point phase.
