input.c has a fixture class for running each selftest with a fresh line_table, and logic for looping over various interesting line_table test cases. This patch exposes the above in selftest.h so that such location-handling tests can be written in other files, renaming the class from temp_line_table to line_table_test. Also, the patch moves the stored line table ptr from being a member of the test class to being a global GC-root, to avoid it being collected if the GC runs during such a test. gcc/ChangeLog: * input.c (saved_line_table): New global.

2016-08-18DWARF: do not emit DW_TAG_variable to materialize DWARF proceduresPierre-Marie de Rodat2-14/+9
Hello, For -gdwarf-3 and newer, the DWARF back-end sometimes generates DWARF procedures to factorize complex location descriptions. DWARF procedures can be materialized as DW_TAG_dwarf_procedure DIEs, but actually any DIE that can hold a DW_AT_location attribute is also accepted. Unlike what I thought at some point, the DW_TAG_dwarf_procedure tag was introduced in the DWARFv3 standard, not the DWARFv4 one, so the back-end can always emit DW_TAG_dwarf_procedure DIEs, as this simplifies code and prevents the types pruning pass from missing a DWARF procedure. Boostrapped and regtested on x86_64-linux: no regression. Ok to commit? Thank you in advance! gcc/ * dwarf2out.c (copy_dwarf_procedure): Remove obsolete comment. (new_dwarf_proc_die): Emit DW_TAG_dwarf_procedure DIEs even for -gdwarf-3. (function_to_dwarf_procedure): Update comment. From-SVN: r239575
2016-08-18Evict selftest tempfiles from the diagnostics file cacheDavid Malcolm4-0/+38
Selftests can use class selftest::temp_source_file to write out files for testing input-handling, and the files are unlinked in the dtor. This leads to stale entries in input.c's cache of file content, which could lead to errors if a temporary filename gets reused during a run of the selftests. We don't normally expect files to be "deleted from under us", so special-case this by adding a special way for temp_source_file's dtor to purge any cache entries referring to it. gcc/ChangeLog: * input.c (diagnostics_file_cache_forcibly_evict_file): New function. * input.h (diagnostics_file_cache_forcibly_evict_file): New declaration. * selftest.c (selftest::temp_source_file::~temp_source_file): Evict m_filename from the diagnostic file cache.
