2022-10-20Add C++ library interface dataUlrich Drepper1-481/+925
This patch adds a CSV file with information about the API of the standard C++ library. This information can be used in multiple ways. So far there are two use cases: - to generate the module export list for the standard C++ library - to create the name hints to compiler emits when symbols in the std namespace are not found Adding more uses can be easily done by potentially adding more columns to the CSV file and adding to the Python script which generates the output file. contrib/ 2022-10-18 Jonathan Wakely <jwakely@redhat.com> Ulrich Drepper <drepper@redhat.com> * gcc_update: Add rule for gcc/cp/std-name-hint.gperf. gcc/cp/ 2022-10-18 Jonathan Wakely <jwakely@redhat.com> Ulrich Drepper <drepper@redhat.com> * Make-lang.in: Add rules to generate std-name-hint.gperf. Adjust rule to generate std-name-hint.h to allow chain rule. * std-name-hint.h: Regenerated. * std-name-hint.gperf: This file is now generated. * cxxapi-data.csv: New file. CSV file with C++ API data. * gen-cxxapi-file.py: New file. Generate std-name-hint.gperf and module export source (in future).
2022-08-30Change get_std_name_hint to use generated hash tableUlrich Drepper1-0/+675
The get_std_name_hint function so far uses linear search to locate matching entries. After adding more hint entries this might not be appropriate anymore. Therefore this patch also replaces the linear array with a gperf-generated hash table. contrib/ChangeLog * gcc_update (files_and_dependencies): Add rule for gcc/cp/std-name-hint.h. gcc/cp/ChangeLog * Make-lang.in: Add rule to rebuild std-name-hint.h from std-name-hint.gperf. * name-lookup.cc (get_std_name_hint): Remove hints array. Use gperf-generated class std_name_hint_lookup. Include "std-name-hint.h". * std-name-hint.gperf: New file. * std-name-hint.h: New file. Generated from the .gperf file.
