The following patch adds streaming of edge goto_locus (both LOCATION_LOCUS and LOCATION_BLOCK from it), the PR shows a testcase (inappropriate for gcc testsuite) where the lack of streaming of goto_locus results in worse debug info. Earlier version of the patch (without the output_function changes) failed miserably, because on the order mismatch - input_function would first input_cfg, then input_eh_regions and then input_bb (all of which now have locations), while output_function used output_eh_regions, then output_bb and then output_cfg. *_cfg went to a separate stream... Now, is there a reason why the order is different? If the intent is that the cfg could be read separately from the rest of function or vice versa, alternatively we'd need to clear_line_info (); before output_eh_regions and before/after output_cfg to make them independent. 2020-09-07 Jakub Jelinek <jakub@redhat.com> PR debug/94235 * lto-streamer-out.c (output_cfg): Also stream goto_locus for edges. Use bp_pack_var_len_unsigned instead of streamer_write_uhwi to stream e->dest->index and e->flags. (output_function): Call output_cfg before output_ssa_name, rather than after streaming all bbs. * lto-streamer-in.c (input_cfg): Stream in goto_locus for edges. Use bp_unpack_var_len_unsigned instead of streamer_read_uhwi to stream in dest_index and edge_flags. |

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.
