* libdw: Apply DWARF package file section offsets where appropriateOmar Sandoval2024-03-011-0/+1412
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The final piece of DWARF package file support is that offsets have to be interpreted relative to the section offset from the package index. .debug_abbrev.dwo is already covered, so sprinkle around calls to dwarf_cu_dwp_section_info for the remaining sections: .debug_line.dwo, .debug_loclists.dwo/.debug_loc.dwo, .debug_str_offsets.dwo, .debug_macro.dwo/.debug_macinfo.dwo, and .debug_rnglists.dwo. With all of that in place, we can finally test various libdw functions on dwp files. * libdw/dwarf_getlocation.c (initial_offset): Call dwarf_cu_dwp_section_info and add offset to start_offset. * libdw/dwarf_getmacros.c (get_macinfo_table): Call dwarf_cu_dwp_section_info and add offset to line_offset. (get_offset_from): Call dwarf_cu_dwp_section_info and add offset to *retp. * libdw/dwarf_getsrcfiles.c (dwarf_getsrcfiles): Call dwarf_cu_dwp_section_info and pass offset to __libdw_getsrclines. * libdw/dwarf_next_lines.c (dwarf_next_lines): Call dwarf_cu_dwp_section_info and add offset to stmt_off. * libdw/libdwP.h (str_offsets_base_off): Call dwarf_cu_dwp_section_info and add offset. (__libdw_cu_ranges_base): Ditto. (__libdw_cu_locs_base): Ditto. * tests/run-all-dwarf-ranges.sh: Check testfile-dwp-5 and testfile-dwp-4. * tests/run-declfiles.sh: Ditto. * tests/run-get-lines.sh: Ditto. * tests/run-next-lines.sh: Ditto. * tests/run-varlocs.sh: Ditto. * tests/run-get-files.sh: Check testfile-dwp-5, testfile-dwp-5.dwp, testfile-dwp-4, and testfile-dwp-4.dwp * tests/run-next-files.sh: Ditto. * tests/run-dwarf-getmacros.sh: Check testfile-dwp-5 and testfile-dwp-4-strict. * tests/run-get-units-split.sh: Ditto.

* Change calling convention of dwarf_getmacros to allow opcode 0xffPetr Machata2014-12-101-0/+11
| | | | | | | | | We now require callers to pass DWARF_GETMACROS_START to start the iteration. 0 is still accepted, but signals to libdw that the iteration request comes from an old-style caller, and that opcode 0xff should be rejected when iterating .debug_macro, to avoid confusion.

* Enable automake parallel-tests for make check.Mark Wielaard2013-04-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The parallel-tests option was introduced in automake 1.11 and is the default since automake 1.13. All tests can now be ran in parallel with make check -j. To enable this all tests are ran in their own temporary directory so they don't stomp on each others input or output files. On my machine (4 cores) make check takes ~20 seconds, but now with make check -j8 takes only ~4 seconds. ChangeLog: * configure.ac (AM_INIT_AUTOMAKE): Request parallel-tests. tests/ChangeLog: * Makefile.am (installed_TESTS_ENVIRONMENT): Export environment, remove wrapper. (TESTS_ENVIRONMENT): Likewise. (installed_LOG_COMPILER): New variable defining wrapper. (LOG_COMPILER): Likewise. * run-*.sh: Fixup location of input and output files. * test-subr.sh: Create test_dir, pushd to execute test in. (trap): Remove test_dir. (testfiles): Use abs_srcdir. (installed_testrun): Match on abs_builddir or abs_top_builddir. (self_test_files): Adjust path. Signed-off-by: Mark Wielaard <[email protected]>
