When running test-case gdb.base/gold-gdb-index.exp on openSUSE Tumbleweed, I run into: ... FAIL: gdb.base/gold-gdb-index.exp: maint info symtabs ... This is due to a dummy .gdb_index: ... Contents of the .gdb_index section: Version 7 CU table: TU table: Address table: Symbol table: ... The dummy .gdb_index is ignored when loading the symbols, and instead partial symbols are used. Consequently, we get the same result as if we'd removed -Wl,--gdb-index from the compilation. Presumably, gold fails to generate a proper .gdb_index because it lacks DWARF5 support. Anyway, without a proper .gdb_index we can't test the gdb behaviour we're trying to excercise. Fix this by detecting whether we actually used a .gdb_index for symbol loading. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2021-07-14 Tom de Vries <tdevries@suse.de> * lib/gdb.exp (have_index): New proc. * gdb.base/gold-gdb-index.exp: Use have_index.
