this patch implement tracking wehther argument points to readonly memory. This is is useful for ipa-modref as well as for inline heuristics. It is desirable to inline functions that dereference pointers to local variables in order to support SRA. We always did the oposite heuristics (guessing that the dereferences will be optimized out with 50% probability) but here we could increase the probability for cases where we can track that argument is indeed a local memory (or readonly which is also good) * ipa-fnsummary.c (dump_ipa_call_summary): Dump points_to_local_or_readonly_memory flag. (analyze_function_body): Compute points_to_local_or_readonly_memory flag. (remap_edge_change_prob): Rename to ... (remap_edge_params): ... this one; update points_to_local_or_readonly_memory. (remap_edge_summaries): Update. (read_ipa_call_summary): Stream the new flag. (write_ipa_call_summary): Likewise. * ipa-predicate.h (struct inline_param_summary): Add points_to_local_or_readonly_memory. (inline_param_summary::equal_to): Update. (inline_param_summary::useless_p): Update. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
