2001-07-16 Daniel Berlin <dan@cgsoftware.com> * gcse.c: Include df.h for use as a dataflow analyzer. Remove regvec. Declaration of reg_set_info: gone. New df_analyzer variable used by store motion. (reg_set_info): Deleted. (mark_mem_regs): New function, analyze regs used by a mem. (store_ops_ok): Use dataflow analyzer results to determine if necessary regs are changed in the block. (find_moveable_store): Remove check for symbol ref, we can handle much more complex expressions now. (compute_store_table): Remove most of the code, it's unnecessary now that the dataflow analyzer records the info for us. (store_killed_after): Add parameter to say whether to do the store_ops_okay test, used to speed up testing when we already know the answer, and just want to know if the store itself was killed. (build_store_vector): Largely rewritten to calculate the various vectors properly, and somewhat optimized. (store_motion): Init the df_analyzer, get REG_DEF chains. Also handle trapping expressions (since mems almost always trap) (simple_mem): Redefine what a simple mem is. From-SVN: r44603
