Some of these may be easy to implement, I just haven't had a good example to base the implementation on & test against.
- Groupshared memory
- OPCODE_INTERFACE_CALL
- OPCODE_CALL
- OPCODE_CALLC
- OPCODE_RET (this assumes that we don't have a 'callstack' of function calls to return from, and ends the shader currently)
- OPCODE_LOD
- OPCODE_SAMPLE_POS
- OPCODE_SAMPLE_INFO
- OPCODE_EVAL_SNAPPED
- OPCODE_EVAL_SAMPLE_INDEX
- OPCODE_EVAL_CENTROID
- OPCODE_ATOMIC_AND
- OPCODE_ATOMIC_OR
- OPCODE_ATOMIC_XOR
- OPCODE_ATOMIC_CMP_STORE
- OPCODE_ATOMIC_IMAX
- OPCODE_ATOMIC_IMIN
- OPCODE_IMM_ATOMIC_AND
- OPCODE_IMM_ATOMIC_OR
- OPCODE_IMM_ATOMIC_XOR
- OPCODE_IMM_ATOMIC_EXCH
- OPCODE_IMM_ATOMIC_CMP_EXCH
- OPCODE_IMM_ATOMIC_IADD
- OPCODE_IMM_ATOMIC_IMAX
- OPCODE_IMM_ATOMIC_IMIN
- OPCODE_IMM_ATOMIC_UMAX
- OPCODE_IMM_ATOMIC_UMIN
- OPCODE_CUT
- OPCODE_EMIT
- OPCODE_EMITTHENCUT
- OPCODE_EMIT_STREAM
- OPCODE_CUT_STREAM
- OPCODE_EMITTHENCUT_STREAM
- OPCODE_HS_DECLS
- OPCODE_HS_CONTROL_POINT_PHASE
- OPCODE_HS_FORK_PHASE
- OPCODE_HS_JOIN_PHASE
These are not documented anywhere on the bytecode side, only hlsl side 😩. Most of them are obvious though.
- OPCODE_ABORT
- OPCODE_DEBUGBREAK - ???
- OPCODE_DDIV - double divide
- OPCODE_DFMA - double fused multiply add
- OPCODE_DRCP - double reciprocal
- OPCODE_MSAD
- OPCODE_DTOI - double to int
- OPCODE_DTOU - double to uint
- OPCODE_ITOD - int to double
- OPCODE_UTOD - uint to double
Feedback functions (for tiled resources)
- OPCODE_GATHER4_FEEDBACK
- OPCODE_GATHER4_C_FEEDBACK
- OPCODE_GATHER4_PO_FEEDBACK
- OPCODE_GATHER4_PO_C_FEEDBACK
- OPCODE_LD_FEEDBACK
- OPCODE_LD_MS_FEEDBACK
- OPCODE_LD_UAV_TYPED_FEEDBACK
- OPCODE_LD_RAW_FEEDBACK
- OPCODE_LD_STRUCTURED_FEEDBACK
- OPCODE_SAMPLE_L_FEEDBACK
- OPCODE_SAMPLE_C_LZ_FEEDBACK
- OPCODE_SAMPLE_CLAMP_FEEDBACK
- OPCODE_SAMPLE_B_CLAMP_FEEDBACK
- OPCODE_SAMPLE_D_CLAMP_FEEDBACK
- OPCODE_SAMPLE_C_CLAMP_FEEDBACK
- OPCODE_CHECK_ACCESS_FULLY_MAPPED
