extern unsigned XT_SRLI(unsigned t, immediate i);

Description

(please consult the Xtensa ® Instruction Set Architecture Reference Manual for any cross references and additional information)

SRLI shifts the contents of address register at right, inserting zeros on the left, by a constant amount encoded in the instruction word in the range 0..15. There is no SRLI for shifts >= 16. EXTUI replaces these shifts.
