hi now i'm trying to construct def-use chain after the PASS_LEAF_REGS. for the ssa form structure has been destoried during the former passes. I have found that gcc provides a way to build the def-use chain in the PASS_REGRENAME, but it only contains the defs and uses all in one basic block.
so if I want to get the global def-use data of the whole function, need i to construct it myself ? Does gcc provide any function to build the def-use chain in RTL form? thank you
