This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
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.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
