2019-12-11ubsan: epiphany: left shift of negative valueAlan Modra1-2/+2
Two places in epiphany_cgen_extract_operand, "value" is a long. value = ((((value) << (1))) + (pc)); cpu/ * epiphany.cpu (f-simm8, f-simm24): Use multiply rather than shift left to avoid UB on left shift of negative values. opcodes/ * epiphany-ibld.c: Regenerate.
