1404 * parse_r var, r - Helper assembler macro for parsing register names.
1406 * This converts the register name in $n form provided in \r to the
1407 * corresponding register number, which is assigned to the variable \var. It is
1408 * needed to allow explicit encoding of instructions in inline assembly where
1409 * registers are chosen by the compiler in $n form, allowing us to avoid using
1410 * fixed register numbers.
1412 * It also allows newer instructions (not implemented by the assembler) to be
1413 * transparently implemented using assembler macros, instead of needing separate
1414 * cases depending on toolchain support.
