With DWARF-5 .debug_names the commands are more complicated (as now also .debug_str needs to be modified) and so I have decided to rather reuse contrib/gdb-add-index.sh instead of duplicating its code in contrib/cc-with-tweaks.sh. The problem is when no index is produced whether contrib/cc-with-tweaks.sh should fail or not. As originally contrib/cc-with-tweaks.sh was more quiet (=successful) than contrib/gdb-add-index.sh and so after this patch the testsuite runs with an index would "regress". I have tried to keep the behavior unchanged. Some cases still error with: Ada is not currently supported by the index But some cases (such as some trivial gdb.dwarf2/ testcases with no DWARF data to index) produce no index while the testcases still PASS now instead of: -PASS: gdb.arch/i386-bp_permanent.exp: stack pointer value matches +gdb compile failed, gdb-add-index.sh: No index was created for /quadgdb/testsuite.unix.-m64/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent +gdb-add-index.sh: [Was there no debuginfo?
