One could not call IFUNCs (=indirect functions) from the compiled injected code. Either it errored with: gdb command line:1:1: error: function return type cannot be function or it just called the IFUNC dispatcher in normal way, returning real function implementation address instead of the function return value (and thus no function was called). gdb/ChangeLog 2015-02-26 Jan Kratochvil <jan.kratochvil@redhat.com> * compile/compile-c-symbols.c (convert_one_symbol, convert_symbol_bmsym) (gcc_symbol_address): Call gnu_ifunc_resolve_addr. gdb/testsuite/ChangeLog 2015-02-26 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.compile/compile-ifunc.c: New file. * gdb.compile/compile-ifunc.exp: New file.
