I've fixed it up with the following: diff --git a/target/xtensa/translate.c b/target/xtensa/translate.c index 616ed8f57972..bda4e9469b86 100644 --- a/target/xtensa/translate.c +++ b/target/xtensa/translate.c @@ -865,11 +865,12 @@ struct slot_prop { enum resource_type { RES_REGFILE, RES_STATE, + RES_MAX, }; static uint32_t encode_resource(enum resource_type r, unsigned g, unsigned n) { - assert(r < 256 && g < 256 && n < 65536); + assert(r < RES_MAX && g < 256 && n < 65536); return (r << 24) | (g << 16) | n; } and pushed the updated tag 20190228-xtensa.
