[NFCI][lldb][test] Fix mismatched C/C++ substitutions (#165773) 2025-10-30T21:18:32+00:00 Raul Tambre raul@tambre.ee 2025-10-30T21:18:32+00:00 21041c92925faf529717d96279b6d8f20b17c70c Most of the cases were where a C++ file was being compiled with the C substitution. There were a few cases of the opposite though. LLDB seems to be the only real culprit in the LLVM codebase for these mismatches. Rest of the LLVM presumably sticks at least language-specific options in the common substitutions making the mistakes immediately apparent. I found these by using Clang frontend configuration files containing language-specific options for both C and C++ (e.g. `-std=c2y` and `-std=c++26`).

 [LLDB] Impove ObjectFileELF's .dynamic parsing and usage. (#102570) 2024-08-12T17:57:04+00:00 Greg Clayton gclayton@fb.com 2024-08-12T17:57:04+00:00 f1e2886261281e788e4faae406c24e787c1dbdd0 This patch improves the ability of a ObjectFileELF instance to read the .dynamic section. It adds the ability to read the .dynamic section from the PT_DYNAMIC program header which is useful for ELF files that have no section headers and for ELF files that are read from memory. It cleans up the usage of the .dynamic entries so that ObjectFileELF::ParseDynamicSymbols() is the only code that parses .dynamic entries, teaches that function the read and store the string values for each .dynamic entry. We now dump the .dynamic entries in the output of "image dump objfile". It also cleans up the code that gets the dynamic string table so that it can grab it from the DT_STRTAB and DT_STRSZ .dynamic entries for when we have a ELF file with no section headers or we are reading it from memory.
