A number of testcases define variables and/or functions which are referenced by GDB during the test, but which are not referenced from within the test executable. Clang correctly recognizes that these variables and functions are unused, and optimizes them out, causing the testcases in question to fail. This commit adds __attribute__ ((used)) in various places to prevent this. gdb/testsuite/ChangeLog: * gdb.base/msym-bp.c (foo): Add __attribute__ ((used)). * gdb.base/msym-bp-2.c (foo): Likewise. * gdb.base/msym-lang.c (foo): Likewise. * gdb.base/msym-lang-main.c (foo): Likewise. * gdb.base/symtab-search-order-1.c (static_global): Likewise. * gdb.guile/scm-pretty-print.c (eval_func): Likewise. * gdb.mi/mi-sym-info-1.c (global_f1): Likewise. * gdb.mi/mi-sym-info-2.c (global_f1, var1, var2): Likewise. * gdb.multi/watchpoint-multi-exit.c (globalvar): Likewise. * gdb.python/py-as-string.c (enum_valid, enum_invalid): Likewise. * gdb.python/py-objfile.c (static_var): Likewise. * gdb.python/py-symbol.c (rr): Likewise. * gdb.python/py-symbol-2.c (anon, rr): Likewise. * gdb.mi/mi-sym-info.exp (lineno1, lineno2): Updated.
