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 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].
