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.

When using gdb.lookup_static_symbol I think that GDB should find
static symbols (global symbol with static linkage) from the current
object file ahead of static symbols from other object files.
This means that if we have two source files f1.c and f2.c, and both
files contains 'static int foo;', then when we are stopped in f1.c a
call to 'gdb.lookup_static_symbol ("foo")' will find f1.c::foo, and if
we are stopped in f2.c we would find 'f2.c::foo'.
Given that gdb.lookup_static_symbol always returns a single symbol,
but there can be multiple static symbols with the same name GDB is
always making a choice about which symbols to return. I think that it
makes sense for the choice GDB makes in this case to match what a user
would get on the command line if they asked to 'print foo'.
gdb/testsuite/ChangeLog:
* gdb.python/py-symbol.c: Declare and call function from new
py-symbol-2.c file.
* gdb.python/py-symbol.exp: Compile both source files, and add new
tests for gdb.lookup_static_symbol.
* gdb.python/py-symbol-2.c: New file.
gdb/doc/ChangeLog:
* python.texi (Symbols In Python): Extend documentation for
gdb.lookup_static_symbol.
gdb/ChangeLog:
* python/py-symbol.c (gdbpy_lookup_static_symbol): Lookup in
static block of current object file first. Also fix typo in
header comment.
