From b44293099e215d6558a8d91b5eaab137218d2e27 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 4 Aug 2023 15:02:43 +0200 Subject: [gdb/testsuite] Extend gdb.base/index-cache.exp The test-case gdb.base/index-cache.exp uses only one source file, which contains main. While doing "file $exec", in set_initial_language a symbol lookup of "main" is done, causing the symtab containing main to be expanded. Handling of main is special, and a future optimization may skip the lookup and expansion. Reliably exercise: - the lookup of main, expanding the symtab containing main, by doing "ptype main", and - the lookup of another symbol, expanding a symtab not containing main, by: - adding another source file containing function foo, and - doing "ptype foo". This triggered a segfault with target board native-extended-gdbserver, filed as PR symtab/30712, but that seems to be fixed by a previous commit in this series. Tested on x86_64-linux.
