◆ calcAddr() [1/2]

void Gcn3ISA::Inst_SMEM::calcAddr ( GPUDynInstPtr  gpu_dyn_inst,
ConstScalarOperandU128 &  s_rsrc_desc,
ScalarRegU32  offset 
)
inlineprotected

For s_buffer_load_dword/s_buffer_store_dword instruction addresses.

The s_buffer instructions use the same buffer resource descriptor as the MUBUF instructions.

The address is clamped if: Stride is zero: clamp if offset >= num_records Stride is non-zero: clamp if offset > (stride * num_records)
