2016-02-09Modernize configure.ac'sSimon Marchi1-1/+3
Using AC_OUTPUT with arguments has been deprecated for some time in autoconf, even in version 2.64, which we are using. This change should not affect functionality. I also removed the "exit 0"'s, they shouldn't be necessary. gdb/ChangeLog: * configure.ac: Use AC_CONFIG_FILES instead of passing arguments to AC_OUTPUT. Remove "exit 0" at the end. * configure: Regenerate. gdb/testsuite/ChangeLog: * configure.ac: Use AC_CONFIG_FILES instead of passing arguments to AC_OUTPUT. * configure: Regenerate. gdb/gdbserver/ChangeLog: * configure.ac: Use AC_CONFIG_FILES instead of passing arguments to AC_OUTPUT. * configure: Regenerate.

2016-01-12gdbserver: use the new gdb warning helpersMike Frysinger1-74/+7
We need to use -Wno-missing-prototypes for now as much of the code sticks externs in local files and not in common headers. 2016-01-11 Mike Frysinger <vapier@gentoo.org> * acinclude.m4: Include new ../warning.m4 file. * configure: Regenerated. * configure.ac: Replace all warning logic with AM_GDB_WARNINGS.

2015-12-16Fix -Wno-unknown-warning support detectionPedro Alves1-2/+11
Ref: https://sourceware.org/ml/gdb/2015-12/msg00024.html We have code in configure.ac that tries to detect whether the compiler supports each warning and suppress it if not, but that doesn't work with "-Wno-" options, because gcc doesn't error out for -Wno-unknown-warning unless other diagnostics are being produced. See https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html. Handle this by checking whether -Wfoo works when we actually want -Wno-foo. gdb/ChangeLog: 2015-12-16 Pedro Alves <palves@redhat.com> * configure.ac (compiler warning flags): When testing a -Wno-foo option, check whether -Wfoo works instead. * configure: Regenerate. gdb/gdbserver/ChangeLog: 2015-12-16 Pedro Alves <palves@redhat.com> * configure.ac (compiler warning flags): When testing a -Wno-foo option, check whether -Wfoo works instead. * configure: Regenerate.

Both x86_64 GNU/Linux and x86_64 mingw-w64 build cleanly with --enable-targets=all. This enables -Werror by default in C++ mode too, in order to let the buildbot catch C++ build regressions for us. gdb/ChangeLog: 2015-11-19 Pedro Alves <palves@redhat.com> * configure.ac (ERROR_ON_WARNING): Don't check whether in C++ mode. * configure: Regenerate. gdb/gdbserver/ChangeLog: 2015-11-19 Pedro Alves <palves@redhat.com> * configure.ac (ERROR_ON_WARNING): Don't check whether in C++ mode. * configure: Regenerate.
2015-07-24make gdbserver use the same ptrace autoconf checks as gdbPedro Alves1-0/+3
This factors the ptrace checks out of gdb's configure.ac to a new ptrace.m4 file, and then makes gdbserver's configure.ac source it too. gdb/ChangeLog: 2015-07-24 Pedro Alves <palves@redhat.com> * acinclude.m4: Include ptrace.m4. * configure.ac: Call GDB_AC_PTRACE and move ptrace checks ... * ptrace.m4: ... to this new file. gdb/gdbserver/ChangeLog: 2015-07-24 Pedro Alves <palves@redhat.com> * acinclude.m4: Include ../ptrace.m4. * configure.ac: Call GDB_AC_PTRACE. * config.in, configure: Regenerate.

The following patch... | proc-service, extern "C" | | libthread_db.so calls symbols in the client (GDB), through the | proc-service interface. These routines must have extern "C" linkage | so their symbol names are not mangled when GDB is built as a C++ | program.

The problem comes from type prfpregset_t not being declared: /[...]/gdbserver/gdb_proc_service.h:98:47: error: unknown type name 'prfpregset_t' After searching through the includes of the install we have, I could not find that type being declared anywhere. So I did the same as for prgregset_t, and created the typedef if the type isn't declared. gdb/gdbserver/ChangeLog: * configure.ac: Add prfpregset_t BFD_HAVE_SYS_PROCFS_TYPE check. * configure, config.in: Regenerate. * gdb_proc_service.h [HAVE_PRFPREGSET_T] (prfpregset_t): Declare typedef.

2015-03-07Remove C-specific warnings from common warning setPedro Alves1-1/+3
Whoops, these are C specific, but I somehow missed the warnings before: cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++ [enabled by default] cc1plus: warning: command line option ‘-Wdeclaration-after-statement’ is valid for C/ObjC but not for C++ [enabled by default] cc1plus: warning: command line option ‘-Wmissing-parameter-type’ is valid for C/ObjC but not for C++ [enabled by default] cc1plus: warning: command line option ‘-Wold-style-declaration’ is valid for C/ObjC but not for C++ [enabled by default] cc1plus: warning: command line option ‘-Wold-style-definition’ is valid for C/ObjC but not for C++ [enabled by default] gdb/ChangeLog: 2015-03-07 Pedro Alves <palves@redhat.com> * configure.ac (build_warnings): Move -Wmissing-prototypes -Wdeclaration-after-statement -Wmissing-parameter-type -Wold-style-declaration -Wold-style-definition to the C-specific set. * configure: Regenerate. gdb/gdbserver/ChangeLog: 2015-03-07 Pedro Alves <palves@redhat.com> * configure.ac (build_warnings): Move -Wdeclaration-after-statement to the C-specific set. * configure: Regenerate.
2015-02-27Add --enable-build-with-cxx configure switchPedro Alves1-3/+30
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: In function ‘void do_restore_infcall_suspend_state_cleanup(void*)’: 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] attstr = "editable"; ^ 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. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * Makefile.in (COMPILER): New, get it from autoconf.

2015-02-27Create libiberty.m4, have GDB and GDBserver use itPedro Alves1-0/+2
Converting GDB to be a C++ program, I stumbled on 'basename' issues, 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 pull in the autoconf checks that libiberty clients needs done in order to use these libiberty.h/ansidecl.h. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * libiberty.m4: New file. * acinclude.m4: Include libiberty.m4. * configure.ac: Call libiberty_INIT. * config.in, configure: Regenerate. gdb/gdbserver/ 2015-02-27 Pedro Alves <palves@redhat.com> * acinclude.m4: Include libiberty.m4. * configure.ac: Call libiberty_INIT. * config.in, configure: Regenerate.
2015-01-15Move safe_strerror to common/Sergio Durigan Junior1-1/+5
This patch moves safe_strerror from the gdb/{posix,mingw}-hdep.c files to the respective common/{posix,mingw}-strerror.c files. This is a preparation for the next patch, which shares a common code (to disable address space randomization when creating a new inferior).

2015-01-14Detect 64-bit-ness in PowerPC Book III-EYao Qi1-1/+1
This patch is to teach both GDB and GDBServer to detect 64-bit inferior correctly. We find a problem that GDBServer is unable to detect on a e5500 core processor. Current GDBServer assumes that MSR is a 64-bit register, but MSR is a 32-bit register in Book III-E. This patch is to fix this problem by checking the right bit in MSR, in order to handle both Book III-S and Book III-E. In order to detect Book III-S and Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by getauxval on glibc >= 2.16. If getauxval doesn't exist, we implement the fallback by parsing /proc/self/auxv), because it should an invariant on the same machine cross different processes. In order to share code, I add nat/ppc-linux.c for both GDB and GDBserver side. gdb: 2015-01-14 Yao Qi <yao@codesourcery.com> * Makefile.in (ppc-linux.o): New rule. * config/powerpc/ppc64-linux.mh (NATDEPFILES): Add ppc-linux.o. * configure.ac: AC_CHECK_FUNCS(getauxval). * config.in: Re-generated. * configure: Re-generated. * nat/ppc-linux.h [__powerpc64__] (ppc64_64bit_inferior_p): Declare. * nat/ppc-linux.c: New file. * ppc-linux-nat.c (ppc_linux_target_wordsize) [__powerpc64__]: Call ppc64_64bit_inferior_p. gdb/gdbserver: 2015-01-14 Yao Qi <yao@codesourcery.com> * Makefile.in (SFILES): Add nat/ppc-linux.c.

2014-12-13configure gdb/gnulib with --disable-largefile if largefile support disabled.Joel Brobecker1-1/+8
This patch mostly aims at fixing a GDB build failure on 32bit Solaris systems (Sparc and x86), due to a recent gnulib update adding the readlink module. But it might also fix related issues when configuring with --disable-largefile. A side-effect of the gnulib readlink module addition is that it caused largefile support to be added as well, and in particular gnulib/import/m4/largefile.m4 introduced the following new #define in gnulib's config.in: | +/* Number of bits in a file offset, on hosts where this is settable. */ | +#undef _FILE_OFFSET_BITS When defined to 64, it triggers an issue with procfs.h while trying to build sparc-sol2-nat.c: | #if !defined(_LP64) && _FILE_OFFSET_BITS == 64 | #error "Cannot use procfs in the large file compilation environment" | #endif As it turns out, this is a fairly familiar problem, and one of the reasons behind ACX_LARGEFILE having been created. In that macro, we have some code which disables largefile support on solaris hosts: | sparc-*-solaris*|i[3-7]86-*-solaris*) | changequote([,])dnl | # On native 32bit sparc and ia32 solaris, large-file and procfs support | # are mutually exclusive; and without procfs support, the bfd/ elf module | # cannot provide certain routines such as elfcore_write_prpsinfo | # or elfcore_write_prstatus. So unless the user explicitly requested | # large-file support through the --enable-largefile switch, disable | # large-file support in favor of procfs support. | test "${target}" = "${host}" -a "x$plugins" = xno \ | && : ${enable_largefile="no"} | ;; But gnulib ignores this fact, and so tries to determine how to enable large-file support irrespective of whether we want it or not. This patch fixes the issue by passing --disable-largefile to gnulib's configure when large-file support in GDB is disabled. This is done by first enhancing ACX_CONFIGURE_DIR to allow us to pass extra arguments to be passed to the configure command, and then by modifying GDB's configure to pass --disable-largefile if large-file support is disabled. gdb/ChangeLog: * acx_configure_dir.m4 (ACX_CONFIGURE_DIR): Add support for new "EXTRA-ARGS" parameter. * configure.ac: If large-file support is disabled in GDB, pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib". * configure: Regenerate. gdb/gdbserver/ChangeLog: * configure.ac: If large-file support is disabled in GDBserver, pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib". * configure: Regenerate. Tested by rebuilding on sparc-solaris and x86_64-linux (with gdbserver). This fixes the build failure on sparc-solaris. I also verified in gnulib's config.log file that we pass --disable-largefile in the solaris case, while we do not in the GNU/Linux case.
2014-11-28Use readlink unconditionallyYao Qi1-1/+1
Since readlink module is imported, we can use it unconditionally. This patch is to remove configure checks and HAVE_READLINK checks in code. It was mentioned in the patch below [RFA/commit] gdbserver: return ENOSYS if readlink not supported. https://sourceware.org/ml/gdb-patches/2012-02/msg00148.html to use readlink in gdbserver, but we chose something simple at that moment. gdb: 2014-11-28 Yao Qi <yao@codesourcery.com> * configure.ac (AC_CHECK_FUNCS): Remove readlink. * config.in, configure: Re-generate. * inf-child.c (inf_child_fileio_readlink): Don't check HAVE_READLINK is defined. gdb/gdbserver: 2014-11-28 Yao Qi <yao@codesourcery.com> * configure.ac(AC_CHECK_FUNCS): Remove readlink. * config.in, configure: Re-generate. * hostio.c (handle_unlink): Remove code checking HAVE_READLINK is defined.
2014-11-21Include alloca.h unconditionallyYao Qi1-3/+1
Since gnulib alloca module was imported, we can include alloca.h in both gdb and gdbserver unconditionally, so this patch adds inclusion of alloca.h in common-defs.h. This patch also removes AC_FUNC_ALLOCA in configure.ac because we don't need to check alloca any more. This patch below is removed in fact. [RFA/commit] include alloca.h if available. https://www.sourceware.org/ml/gdb-patches/2010-08/msg00566.html Since alloca.h is from gnulib now, we don't have to check malloc.h in configure and include malloc.h in code. This patch also remove them too. gdb: 2014-11-21 Yao Qi <yao@codesourcery.com> * common/common-defs.h: Include alloca.h * configure.ac: Don't invoke AC_FUNC_ALLOCA. * configure: Re-generated. * defs.h: Remove code handling alloca. * utils.c (gdb_realpath): Don't check HAVE_ALLOCA is defined or not. gdb/gdbserver: 2014-11-21 Yao Qi <yao@codesourcery.com> * configure.ac: Don't invoke AC_FUNC_ALLOCA.

2014-08-07Move errno.h to common-defs.hGary Benson1-1/+1
This commit moves the inclusion of errno.h to common-defs.h and removes all other inclusions. Note that prior to this commit server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".

2014-06-05Make it easy to make --disable-werror the default for both binutils and gdbJoel Brobecker1-1/+1
The goal of this patch is to provide an easy way to make --disable-werror the default when building binutils, or the parts of binutils that need to get built when building GDB. In development mode, we want to continue making -Werror the default with GCC. But, when making releases, I think we want to make it as easy as possible for regular users to successfully build from sources. GDB already has this kind of feature to turn -Werror as well as the use of the libmcheck library. As GDB Release Manager, I take advantage of it to turn those off after having cut the branch. I'd like to be able to do the same for the binutils bits. And perhaps Tristan will want to do the same for his releases too (not sure, binutils builders might be a little savvier than GDB builders). This patch introduces a new file, called development.sh, which just sets a variable called $development. In our development branches (Eg. "master"), it's set to true. But setting it to false would allow us to change the default behavior of various development-related features to be turned off; in this case, it turns off the use of -Werror by default (use --enable-werror to turn it back on). bfd/ChangeLog: * development.sh: New file. * warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh. Make -Werror the default with GCC only if DEVELOPMENT is true. * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add $(srcdir)/development.sh. * Makefile.in, configure: Regenerate. binutils/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gas/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gold/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): New. * Makefile.in, configure: Regenerate. gprof/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. ld/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. opcodes/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gdb/ChangeLog: * development.sh: Delete. * Makefile.in (config.status): Adjust dependency on development.sh. * configure.ac: Adjust development.sh source call. * configure: Regenerate. gdb/gdbserver/ChangeLog: * configure.ac: Adjust development.sh source call. * Makefile.in (config.status): Adjust dependency on development.sh. * configure: Regenerate. Tested on x86_64-linux by building two ways: One with DEVELOPMENT set to true, and one with DEVELOPMENT set to false. In the first case, I could see the use of -Werror, while it disappeared in the second case.
2014-05-20Do not build gdbserver with -Werror by default if development=falseJoel Brobecker1-2/+2
On GDB release branches, we change $development in gdb/development.sh to false, in order to build the GDB release without -Werror by default, thus avoiding harmless compiler warnings from breaking the build of someone who's only interested in building GDB rather than working on it. This patch implements the same strategy for gdbserver, using the exact same method. gdb/gdbserver/ChangeLog: * configure.ac: Only use -Werror by default when DEVELOPMENT is true. * configure: Regenerate. Tested on x86_64-linux, by rebuilding GDBserver first with development set to true, and then doing it again with development set to false. Werror was used in the first case, but not in the second.

2013-11-08introduce common.m4Tom Tromey1-0/+2
It has bothered me for a while that files in common/ use macros defined via autoconf checks, but rely on each configure.ac doing the proper checks independently. This patch introduces common/common.m4 which consolidates the checks assumed by code in common. The rule I propose is that if something is needed or used by common, it should be checked for by common.m4. However, if the check is also needed by gdb or gdbserver, then it should be duplicated there. Built and regtested on x86-64 Fedora 18 (though this is hardly the most strenuous case) and using the Fedora 18 mingw cross compilers. I also examined the config.in diffs to ensure that symbols did not go missing. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4. * common/common.m4: New file. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4, codeset.m4. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON.

2013-07-03On mainline/development, also link GDBserver with -lmcheck.Pedro Alves1-0/+12
This factors --enable-libmcheck related bits from GDB's configure.ac and makes GDBserver use them too. Specifically, the 'development' global is moved to a separate script to it can be sourced by both GDB and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits proper are moved to a new m4 file. I started out by defining 'development' in the m4 file, but in the end decided against it, as a separate script has the advantage that changing it in release branches does not require regenerating configure, unlike today. I had also started out by making the new GDB_AC_LIBMCHECK itself handle the yes/no default fallback depending on release/developement, but since I had split out 'development' to a separate script, and, GDB needs the python checks anyway (hence we'd need to do the python checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no' parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's the caller's business to handle it. Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without --enable-libmcheck, and observed --enable-libmcheck overrides the disablement of -lmcheck caused by python supporting threads, and that GDBserver links with -lmcheck when expected. Also observed that changing the 'development' global, and issuing "make" triggers a relink, and '-lmcheck' is included or not from the link accordingly. gdb/ 2013-07-03 Pedro Alves <palves@redhat.com> * Makefile.in (config.status): Depend on development.sh.
