Hi, While compiling Nuttx the following error was triggered: ``` common/xtensa_windowspill.S:153:15: error: expected immediate in range [0, 15] srli a3, a3, 32-(64 / 4) ``` In 8.3.307, [the ISA reference](https://www.cadence.com/content/dam/cadence-www/global/en_US/documents/tools/ip/tensilica-ip/isa-summary.pdf) mentions that if the immediate is greater than 15 the instruction should be converted to extui. At the moment the assembler does not do that and takes the semantics of _srli which generates an error when the argument is not in range [0, 15].
