To simplify SM 6 support, insert a control point id relative address where needed, and declare control point phase inputs where missing.
-- v6: vkd3d-shader/ir: Insert hull shader control point input declarations if no control point phase is defined.
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 | 101 +++++++++++++++++++++++ libs/vkd3d-shader/spirv.c | 32 ++----- libs/vkd3d-shader/vkd3d_shader_private.h | 3 + 3 files changed, 111 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 | 86 ++++++++++- libs/vkd3d-shader/spirv.c | 178 +++-------------------- libs/vkd3d-shader/vkd3d_shader_private.h | 11 +- 3 files changed, 112 insertions(+), 163 deletions(-)

We have enough existing FIXMEs in vkd3d-shader that I won't block this series for it, but please note that as a rule vkd3d-shader should use vkd3d_shader_error() and its variants to report this kind of issue to the user of the API, instead of using FIXME and/or ERR.
