localedef: Update LC_MONETARY handling (Bug 28845)
ISO C17, POSIX Issue 7, and ISO 30112 all allow the char*
types to be empty strings i.e. "", integer or char values to
be -1 or CHAR_MAX respectively, with the exception of
decimal_point which must be non-empty in ISO C. Note that
the defaults for mon_grouping vary, but are functionaly
equivalent e.g. "\177" (no further grouping reuqired) vs.
"" (no grouping defined for all groups).
We include a broad comment talking about harmonizing ISO C,
POSIX, ISO 30112, and the default C/POSIX locale for glibc.
We reorder all setting based on locale/categories.def order.
We soften all missing definitions from errors to warnings when
defaults exist.
Given that ISO C, POSIX and ISO 30112 allow the empty string
we change LC_MONETARY handling of mon_decimal_point to allow
the empty string. If mon_decimal_point is not defined at all
then we pick the existing legacy glibc default value of
<U002E> i.e. ".".
We also set the default for mon_thousands_sep_wc at the
same time as mon_thousands_sep, but this is not a change in
behaviour, it is always either a matching value or L'\0',
but if in the future we change the default to a non-empty
string we would need to update both at the same time.

hppa: Revise gettext trampoline design
The current getcontext return trampoline is overly complex and it
unnecessarily clobbers several registers. By saving the context
pointer (r26) in the context, __getcontext_ret can restore any
registers not restored by setcontext. This allows getcontext to
save and restore the entire register context present when getcontext
is entered. We use the unused oR0 context slot for the return
from __getcontext_ret.
While this is not directly useful in C, it can be exploited in
assembly code. Registers r20, r23, r24 and r25 are not clobbered
in the call path to getcontext. This allows a small simplification
of swapcontext.
It also allows saving and restoring the 6-bit SAR register in the
LSB of the oSAR context slot. The getcontext flag value can be
stored in the MSB of the oSAR slot.

This change fixes the failure of stdlib/tst-setcontext2 and

in C is broken. C saves the return pointer (rp) and any non

stack and subsequent calls clobber the saved registers. When
the context in oucp is restored, both tests fault.
Here we rewrite swapcontext in assembly code to avoid using
the stack for register values that need to be used after
restoration. The getcontext and setcontext routines are
revised to save and restore register ret1 for normal returns.
We copy the oucp pointer to ret1. This allows access to
the old context after calling getcontext and setcontext.

This reverts commit
8c8510ab2790039e58995ef3a22309582413d3ff. The
revert is not perfect because the commit included a bug fix for
_dl_sysdep_start with an empty argv, introduced in commit
2d47fa68628e831a692cba8fc9050cef435afc5e ("Linux: Remove

The revert is necessary because the reverted commit introduced an
early memset call on aarch64, which leads to crash due to lack of TCB

malloc: Remove LD_TRACE_PRELINKING usage from mtrace
The fix for BZ#22716 replacde LD_TRACE_LOADED_OBJECTS with
LD_TRACE_PRELINKING so mtrace could record executable address
position.
To provide the same information, LD_TRACE_LOADED_OBJECTS is
extended where a value or '2' also prints the executable address
as well. It avoid adding another loader environment variable
to be used solely for mtrace. The vDSO will be printed as
a default library (with '=>' pointing the same name), which is
ok since both mtrace and ldd already handles it.
The mtrace script is changed to also parse the new format. To
correctly support PIE and non-PIE executables, both the default
mtrace address and the one calculated as used (it fixes mtrace
for non-PIE exectuable as for BZ#22716 for PIE).

On hppa, a function pointer returned by la_symbind is actually a function

the first word of the descriptor is the physical address of theA function,
otherwise, the first word of the descriptor points to a trampoline in the
PLT.
This patch also adds a workaround on tests because on hppa (and it seems
