------- Additional Comments From jakub at gcc dot gnu dot org 2005-01-24 10:30 ------- Regarding the question in #11: LOG_LINKS only point to instructions in the same basic block: /* Set up in flow.c; empty before then. Holds a chain of INSN_LIST rtx's whose first operands point at previous insns with direct data-flow connections to this one. That means that those insns set variables whose next use is in this insn. They are always in the same basic block as this insn. */ #define LOG_LINKS(INSN) XEXP(INSN, 7)
