-- gerrit commit 99e2ac71e462e3f9643057798e93721b657a0334 Author: Salvador Arroyo <[email protected]> Date: Wed Mar 1 20:45:32 2017 +0100 mips32, convert miniprograms with code definition Needed to run in micromips mode. Seems that if an isa is supported in debug mode it also supported in kernel mode. The contrary is not true.
