Adapts __ppc_get_timebase to the upcoming GCC 4.8 that provides
__builtin_ppc_get_timebase. Building applicationns with previous
versions of GCC will continue to use the internal implementation.
The tile architecture's Linux port installs headers in an
<arch> directory; these headers are in part shared with glibc.
Ignore these headers for check-local-headers like we ignore
all the other Linux headers.
This hook is useful for any arch-specific functionality that
should be done on loaded objects. For the tile architecture,
the hook is already provided (though we switch to using the new
macro name with this commit) and implements a simulator notifier
so that the simulator can load Elf symbols to match the object
and generate better error messages for PC's.
Also, remove a spurious definition of DL_UNMAP in dl-runtime.c
When glibc is built with --enable-static-nss, the warning that
using NSS symbols requires the nss shared objects to be present
is no longer true, as those symbols are built into libc. Suppress
the warning for those symbols by providing a new macro
(nss_interface_function) for the NSS functions that is defined as
static_link_warning in the normal case, and empty for static NSS.
* elf/Makefile (tests): Remove conditional for have-initfini-array
since this is now always required and the variable does not exist
anymore.
(tests-static): Likewise.
(modules-names): Likewise.
* elf/tst-array1.c (fini_array): Make writeable so that it can be
merged with constructor/destructor.
(init_array): Likewise.
* elf/tst-array2dep.c (fini_array): Likewise.
(init_array): Likewise.
We must save and restore r19 in both PIC and non-PIC
situations since the kernel paths that clobber r19
are independent of that PIC-ness of userspace.
In addition we choose r4 as the temporary register over
r3 which is being used by recent gcc's as the frame
pointer.
Putting @cartouche inside of @smallexample does not work with HTML output
as the former produces a <table> while the latter produces a <pre>. You
cannot nest a <table> in a <pre> as the contents are no longer formatted.
Since it's entirely unnecessary, and none of the other examples do this,
just drop the cartouche.
