breakpoint-in-ro-region.exp: Support targets stopping in mid-line after "si"

On some targets each of the assignments "i = 0" in the C source for
"breakpoint-in-ro-region.exp" are compiled to a single instruction.
Then each "si" stops at the beginning of the next source line.  But on
some other targets (like s390) such an assignment compiles to multiple
instructions.  Then "si" may stop in mid-line, and GDB displays the PC
address in addition to the source line number.  This was not considered
by the regexp for this case.

gdb/testsuite/ChangeLog:

* gdb.base/breakpoint-in-ro-region.exp (test_single_step): In the
regexps for GDB's current line display, accept a hex address
preceding the line number.

gdbarch_printable_names() walks through the linked list of BFD arches

Joel Brobecker [Mon, 2 Mar 2015 14:01:23 +0000 (06:01 -0800)]
Remove use of stdbool.h in GDB sources.

Using type bool from stdbool unfortunately causes problems trying
to build GDB on AiX and Solaris:

    In file included from ../../src/gdb/utils.h:24:0,
                     from ../../src/gdb/defs.h:707,
                     from ../../src/gdb/utils.c:20:
    /[...]/curses.h:96:14: error: two or more data types in declaration
    specifiers
     typedef char bool;
                  ^
    make[2]: *** [utils.o] Error 1

In theory, the problem is in curses.h which, in both cases, do
something similar. On Solaris:

    #if !defined(__cplusplus) && !defined(_BOOL)
    typedef char bool;
    #endif /* !defined(__cplusplus) && !defined(_BOOL) */

On AiX:

    #if !defined(__cplusplus) || (defined(__IBMCPP__) &&(__IBMCPP__<400))
    #ifndef _BOOL
    #define _BOOL
    typedef int bool;
    #endif
    #endif

You can reproduce the same problem by trying to compile:

    % cat toto.c
    #include <stdbool.h>
    #include <curses.h>
    % gcc -c toto.c
    In file included from toto.c:1:0:
    /[...]/curses.h:159:13: error: two or more data types in declaration
    specifiers
     typedef int bool;
             ^

This specific issue wouldn't occur if we included curses.h before
including stdbool.h, and I looked at that just to be complete.
Here is a small schematic representation of the include logic:

  * utils.c:
      -> defs.h -> utils.h -> stdbool.h
      -> gdb_curses.h -> curses.h

Because defs.h should always be first on the list, it means that
stdbool.h will always necessarily be included ahead of curses.h.

But, thinking beyond this very specific issue, it shows that using
stdbool.h is going to cause problems on these systems until either
GCC fixes those includes in a way that makes them work; or we switch
to C++.

In the meantime, I think the path of least resistance is to revert
the use of stdbool.h, and use integers, the way we've done up until
now. The benefits of using type "bool" are modest, IMO, so not
a great loss, and a temporary one.

gdb/ChangeLog:

        * utils.h: Remove <stdbool.h> #include.
        (producer_is_gcc): Change return type to "int".
        * utils.c (producer_is_gcc): Change return type to int.
        Return 1 instead of true, and 0 instead of false.
        Adjust function documentation accordingly.

C++ keyword cleanliness, mostly auto-generated

This patch renames symbols that happen to have names which are
reserved keywords in C++.

Most of this was generated with Tromey's cxx-conversion.el script.
Some places where later hand massaged a bit, to fix formatting, etc.
And this was rebased several times meanwhile, along with re-running
the script, so re-running the script from scratch probably does not
result in the exact same output.  I don't think that matters anyway.

9 years agoAdd --enable-build-with-cxx configure switch
Pedro Alves [Fri, 27 Feb 2015 13:11:25 +0000 (13:11 +0000)]
Add --enable-build-with-cxx configure switch

This new option, disabled by default for now, allows specifying
whether to build GDB, GDBserver, and friends with a C++ (98/03)
compiler.

The name of the switch should be familiar to those who followed GCC's
own C++ conversion process.

. Adding -fpermissive to COMPILER in C++ mode (see the new
build-with-cxx.m4 file) makes errors like these be warnings instead:

  gdb/infrun.c:6597:1: error:   initializing argument 1 of ‘void sig_print_info(gdb_signal)’ [-fpermissive]
   sig_print_info (enum gdb_signal oursig)

  gdb/infrun.c:7164:39: error: invalid conversion from ‘void*’ to ‘infcall_suspend_state*’ [-fpermissive]
     restore_infcall_suspend_state (state);
 ^

so that the compiler carries on compiling the file.  -Werror still
catches the warnings, so nothing is lost, only our lifes are made
easier by concentrating on getting other more important things out of
the way first.

There's no way to quiet those warnings.  Until they're all fixed, when
building in C++ mode, -Werror is disabled by default.

. Adding -Wno-narrowing suppresses thousands of instances of this warning:

  gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
  gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1l’ from ‘LONGEST {aka long int}’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
  gdb/arm-linux-tdep.c:450:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]

We can defer handling those until we target C++11.

. Adding -Wno-sign-compare suppresses thousands of instances of this warning:

  gdb/linux-record.c:1763:32: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
 if (tmpulongest == tdep->fcntl_F_GETLK64)
  ^

. Adding -Wno-write-strings suppresses thousands of instances of this warning:

  gdb/mi/mi-cmd-var.c: In function ‘void mi_cmd_var_show_attributes(char*, char**, int)’:
  gdb/mi/mi-cmd-var.c:514:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]

  gdb/mi/mi-cmd-var.c:516:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
       attstr = "noneditable";
      ^

For now, it's best to hide these warnings from view until we're
'-fpermissive'-clean, and can thus start building with -Werror.
The C compiler has always managed to build working GDBs with these
issues in the code, so a C++ compiler should too.

Create libiberty.m4, have GDB and GDBserver use it

like:

 src/gdb/../include/ansidecl.h:169:64: error: new declaration ‘char* basename(const char*)’
 /usr/include/string.h:597:26: error: ambiguates old declaration ‘const char* basename(const char*)’

which I believe led to this bit in gold's configure.ac:

 dnl We have to check these in C, not C++, because autoconf generates
 dnl tests which have no type information, and current glibc provides
 dnl multiple declarations of functions like basename when compiling
 dnl with C++.
 AC_CHECK_DECLS([basename, ffs, asprintf, vasprintf, snprintf, vsnprintf, strverscmp])

These checks IIUC intend to generate all the HAVE_DECL_FOO symbols
that libiberty.h and ansidecl.h check.

GDB is missing these checks currently, which results in the conflict
shown above.

This adds an m4 file that both GDB and GDBserver's configury use to

Add "../lib/unbuffer_output.c" and use it in gdb.base/interrupt.c

In some scenarios, GDB or GDBserver can be spawned with input _not_
connected to a tty, and then tests that rely on stdio fail with
timeouts, because the inferior's stdout and stderr streams end up
fully buffered.

See discussion here:
  https://sourceware.org/ml/gdb-patches/2015-02/msg00809.html

We have a hack in place that works around this for Windows testing,
that forces every test program to link with an .o file that does
(lib/set_unbuffered_mode.c):

 static int __gdb_set_unbuffered_output (void) __attribute__ ((constructor));
 static int
 __gdb_set_unbuffered_output (void)
 {
   setvbuf (stdout, NULL, _IONBF, BUFSIZ);
   setvbuf (stderr, NULL, _IONBF, BUFSIZ);
 }

That's a bit hacky; it ends up done for _all_ tests.

This patch adds a way to do this unbuffering explicitly from the test
code itself, so it is done only when necessary, and for all
targets/hosts.  For starters, it adjusts gdb.base/interrupt.c to use
it.

Tested on x86_64 Fedora 20, native, and against a remote gdbserver
board file that connects to the target with ssh, with and without -t

Fix print of value type in a corner case of finish

When doing finish in a function, if gdb fails to return a value, gdb
also fails at printing the value type if this type is a struct.

For example :

(gdb) fin
....
Value returned has type: . Cannot determine contents

This patch fixes this by calling type_to_string to print the type
so that we can support these types.

This patch returns the following example output :

(gdb) fin
....
Value returned has type: struct test. Cannot determine contents

Also, this patch modifies structs.exp to check that we return the
correct type.
