commit 7136316123c54aba37fdab166e1bf860e452a4ae Author: Mark Wielaard <mark@klomp.org> Date: Fri Dec 6 15:39:25 2024 +0100 Recognize new DWARF5 DW_LANG constants When using --read-var-info=yes readdwarf3 will try to read and interpret the CU DW_AT_langauge attribute. Since DWARF5 was released a number if new language constants have been introduced. See https://dwarfstd.org/languages.html GCC15 might start emitting some of these when switching to C23 by default. When valgrind --read-var-info=yes encounters an unknown DW_LANG constant it will produce an error and stop processing any further DWARF. Recognize all currently known language constants. In particular recognize DW_LANG_C17, DW_LANG_C23, DW_LANG_C_plus_plus_17, DW_LANG_C_plus_plus_20, DW_LANG_C_plus_plus_23, DW_LANG_Fortran18, DW_LANG_Fortran23, DW_LANG_Ada2005, DW_LANG_Ada2012 and DW_LANG_Rust. https://bugs.kde.org/show_bug.cgi?id=497130 Also added to the VALGRIND_3_24_BRANCH |
