C1: LIR_OpVisitState::maxNumberOfOperands too small

XMLWordPrintable

    • b04

        In LIR_OpVisitState::append() the assertion

        assert(_oprs_len[mode] < maxNumberOfOperands) failed: array overflow

        fails when C1 compiles a method with 8 integer and 13 float parameters because LIR_OpVisitState::maxNumberOfOperands is 20 which is too small because on ppc 8 integer + 13 float = 21 parameters can be passed in registers (see SharedRuntime::java_calling_convention()).
