Hi guys, I am trying to get LRA fully working for ARC, but I've got an issue. Whenever, LRA analyses an instruction having (clobber (match_scratch:SI 3 "=X, ...)) in its pattern I hit the assert in lra-constraints.c:4101, and it seems it has to do with the scratch's 'X' constraint. Do I miss something? Is there any limitation between LRA and scratch operands having in their alternative 'X' constraint?
Any help appreciated, Claudiu
