When running test-case gdb.base/with.exp with target board cc-with-gdb-index,
we have:
...
(gdb) PASS: gdb.base/with.exp: basics: show language
with language ada -- print g_s^M
'g_s' has unknown type; cast it to its declared type^M
(gdb) FAIL: gdb.base/with.exp: basics: with language ada -- print g_s
...
This is due to this bit in dw2_map_matching_symbols:
...
if (dwarf2_per_objfile->index_table != nullptr)
{
/* Ada currently doesn't support .gdb_index (see PR24713). We can get
here though if the current language is Ada for a non-Ada objfile
using GNU index. As Ada does not look for non-Ada symbols this
function should just return. */
return;
}
...
While the reasoning in the comment may be sound from language perspective, it
does introduce an inconsistency in gdb behaviour between:
- having a .gdb_index section, and
- having a .gdb_names section, or a partial symtab, or -readnow.
Fix the inconsistency by completing implementation of
dw2_map_matching_symbols.
Tested on x86_64-linux, both with native and target board
cc-with-debug-index.
