A quick scan of the jallib sources did not reveal any use of tris opcode, so I'd like know what triggered this code. The asm file (compiler output) is helpful for this, since it contains the output code, as well as all (code generating) source. Please let us know what statement for which source file triggered this opcode and - if relevant - where that source file originated.
