Memory attached to instruction bus of the xtensa CPU is only accessible for a limited subset of opcodes. Other opcodes generate an exception with the load/store error cause code. This property complicates use of such systems. Provide a handler that recognizes and transparently fixes such exceptions. The following opcodes are recognized when used outside of FLIX bundles: l32i, l32i.n, l16ui, l16si, l8ui. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> |
