The justification was: // ... FIRST_PSEUDO_REGISTER + 1 // is the maximum number of accesses to hard registers and memory, and // MAX_RECOG_OPERANDS is the maximum number of pseudos that can be // defined by an instruction, so the number of definitions should fit // easily in 16 bits. But while that reasoning holds (I think) for real instructions, it doesn't hold for artificial instructions. I don't think there's any sensible higher limit we can use, so this patch goes for a full unsigned int. gcc/ PR rtl-optimization/108086 * rtl-ssa/insns.h (insn_info): Make m_num_defs a full unsigned int. Adjust size-related commentary accordingly.
