Currently, pre-increment store patterns are written to use two separate operands to represent address base and displacement: stwu $rS, $ptroff($ptrreg) This causes problems when implementing the assembler parser, so this commit changes the patterns to use standard (complex) memory operands like in all other memory access instruction patterns: stwu $rS, $dst To still match those instructions against the appropriate pre_store SelectionDAG nodes, the patch uses the new feature that allows a Pat to match multiple DAG operands against a single (complex) instruction operand.
