7f98f1806a Split up rules for tests using mtrace and something else.
Most glibc tests that use mtrace to verify that there were no memory
leaks from the glibc facilities used in a given test depend on the
.out file of the previous test so that the mtrace test runs mtrace and
nothing else.

Two, however, have a single target combining mtrace with something
else.  In the case of libio/tst-fopenloc.check, the test both compares
the output with an expected baseline and runs mtrace.  In the case of
posix/tst-rxspencer-mem, the test is run (with different command line
from the main run) and then mtrace is run, from the same makefile
target.

This patch splits both of these tests up to use separate makefile
targets for each thing tested; in the tst-rxspencer case, a file
tst-rxspencer-no-utf8.c is created that just includes tst-rxspencer.c,
as is usual for tests where the same code gets tested in different
compile-time or runtime configurations.

Adding $(evaluate-test) to test commands, as in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html>, will no
longer need to insert && between multiple commands, as all tests will
either have just a single command or already use &&.

Tested x86_64.

	* libio/Makefile ($(objpfx)tst-fopenloc.check): Split into
	separate $(objpfx)tst-fopenloc-cmp.out and
	$(objpfx)tst-fopenloc-mem.out targets.
	(tests): Update dependencies.
	* posix/Makefile (tests variable): Add tst-rxspencer-no-utf8.
	(generated): Change tst-rxspencer-mem and tst-rxspencer.mtrace to
	tst-rxspencer-no-utf8-mem and tst-rxspencer-no-utf8.mtrace.

	(tst-rxspencer-no-utf8-ENV): Likewise.

	($(objpfx)tst-rxspencer-mem): Change target to
	$(objpfx)tst-rxspencer-no-utf8-mem.  Depend on

6e89caf118 Split up rules for tests that compare output with baselines.
This patch splits makefile rules that generate a file then run cmp to
check the contents of that file into separate rules to generate and
compare the file.  This simplifies making those tests generate PASS /
FAIL results, by removing the need to insert && between commands in
the test so that a $(evaluate-test) call is reached.  It also avoids
the oddity of the .out file being an intermediate file rather than the
final result generated, as noted for some of these tests in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>.

In many cases, the rule to run the program was no longer needed
because the default rules for running test programs on the host to
generate a .out file sufficed.  (I'm not asserting the commands run
after this patch are *exactly* the same as before, simply that the
rules did nothing special that appeared deliberate or relevant to
anything about what the tests were testing.  In cases where the rules
redirected stderr as well as stdout, I left the existing rule's
redirection in place to avoid changing what gets compared with the
expected results.)

It's clear there is a lot in common between the various -cmp.out rules
and it might be possible in future to refactor them into more generic
support for the case of comparing test output against a baseline.
(Some baselines are *.exp, some *.expect, some directly embedded in
the makefiles, and nptl/tst-cleanupx0.expect appears unused.)

ed9a38e21b Clean up trivially redundant __USE_MISC conditionals.
This patch cleans up cases of __USE_MISC that are trivially redundant
after the recent substitution of __USE_MISC for __USE_BSD and
__USE_SVID: either in constructs such as "defined __USE_MISC ||
defined __USE_MISC", or else (in the bits/mman.h case) a conditional
on __USE_MISC nested inside another __USE_MISC conditional.  (The
cleanups remaining after this patch are still quite large, but it
seems a reasonable piece to separate out.)

498afc54df Combine __USE_BSD and __USE_SVID into __USE_MISC.
This patch cleans up following the obsoletion of _BSD_SOURCE and
_SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC.

The only non-mechanical part of this patch is the changes to
features.h; everything else is simple substitution of __USE_MISC for
the old macros.  Thus, this patch leaves obviously redundant
conditionals such as "defined __USE_MISC || defined __USE_MISC", and
does not update #endif comments where they referred to BSD or SVID in
words instead of the literal macro name.  This is intended to
facilitate patch review by separating the less mechanical changes from
these purely mechanical changes into a separate patch.  (I do intend
to integrate all the changes from
<https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I
believe includes all the trailing comment updates, in subsequent
patches.)

dd7b064cca Remove reference to subdir_lint.out.
The toplevel Makefile's subdir_targets variable refers to
subdir_lint.out.  As far as I can tell, this is not defined or
referenced anywhere else in the tree.  Having .out makefile references
that don't refer to the output from testcases seems confusing; this
patch removes the reference to subdir_lint.out.

indirection.

8756f74004 Stop io/ftwtest deleting its own output.
If you rerun "make check" in a tree where some tests have already been
run, it will rerun io/ftwtest-sh because that test uses ftwtest.out,
the same name to which output is redirected, as its internal temporary
file, and then removes it on exit.

Clearly tests should not be removing the files to which their output
is redirected like that.  This patch changes the script to use a
different file as its internal temporary file, so the actual output
referenced in the makefile isn't removed.

ace614b8a5 soft-fp: support after-rounding tininess detection.
IEEE 754-2008 defines two ways in which tiny results can be detected,
"before rounding" (based on the infinite-precision result) and "after
rounding" (based on the result when rounded to normal precision as if
the exponent range were unbounded).  All binary operations on an
architecture must use the same choice of how tininess is detected.

soft-fp has so far implemented only before-rounding tininess
detection.  This patch adds support for after-rounding tininess
detection.  A new macro _FP_TININESS_AFTER_ROUNDING is added that
sfp-machine.h must define (soft-fp is meant to be self-contained so
the existing tininess.h files aren't used here, though the information
going in sfp-machine.h has been taken from them).  The soft-fp macros
dealing with raising underflow exceptions then handle the cases where
the choice matters specially, rounding a copy of the input to the
appropriate precision to see if a value that's tiny before rounding
isn't tiny after rounding.

Tested for mips64 using GCC trunk (which now uses soft-fp on MIPS, so
supporting exceptions and rounding modes for long double where not
previously supported - this is the immediate motivation for doing this
patch now) together with (a) a patch to sysdeps/mips/math-tests.h to
enable exceptions / rounding modes tests for long double for GCC 4.9
and later, and (b) corresponding changes applied to libgcc's soft-fp
and sfp-machine.h files.  In the libgcc context this is also tested on
x86_64 (also an after-rounding architecture) with testcases for
__float128 that I intend to add to the GCC testsuite when updating
soft-fp there.

(To be clear: this patch does not fix any glibc bugs that were
user-visible in past releases, since after-rounding architectures
didn't use soft-fp in any affected case with support for
floating-point exceptions - so there is no corresponding Bugzilla bug.
Rather, it works together with the GCC changes to use soft-fp on MIPS
to allow previously absent long double functionality to work properly,
and allows soft-fp to be used in glibc on after-rounding architectures
in cases where it couldn't previously be used.)

	* soft-fp/op-common.h (_FP_DECL): Mark exponent as possibly
	unused.
	(_FP_PACK_SEMIRAW): Determine tininess based on rounding shifted
	value if _FP_TININESS_AFTER_ROUNDING and unrounded value is in

c941736c92 Remove _BSD_SOURCE and _SVID_SOURCE.
This is a minimal patch to remove _BSD_SOURCE and _SVID_SOURCE from
the documented user API, making them into aliases for _DEFAULT_SOURCE

those macros and all the exising __USE_* conditionals, on the basis
that all the consequent cleanups will go in followup patches.

cb4a292812 Merge MIPS dl-lookup.c into generic file.
MIPS has its own version of dl-lookup.c to deal with differences
between undefined symbol semantics in the PIC and non-PIC ABIs.  This
is often liable to get out of date with respect to the generic file
(for example, the recent __builtin_expect changes didn't cover ports,
and it's not obvious to anyone changing dl-lookup.c that there would
be architecture-specific versions).

This patch adds a macro that dl-machine.h can define that is used in
the appropriate place in dl-lookup.c, so that MIPS no longer needs its
own version of that file.

Tested for mips64 that the only changes to disassembly of installed
shared libraries appear to be ld.so changes attributable to different
line numbers and paths in assertions.

	* elf/dl-lookup.c (ELF_MACHINE_SYM_NO_MATCH): Define if not

75eff3fe90 Relocate AArch64 from ports to libc.
This patch moves the AArch64 port to the main sysdeps hierarchy.  The
move is essentially:

  git mv ports/sysdeps/aarch64 sysdeps/aarch64
  git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64

The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move.  The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.

2ad7600be7 Move mips from ports to libc.
I've moved the MIPS port from ports to the main sysdeps hierarchy.
Beyond the README update, the move of the files was simply

git mv ports/sysdeps/mips sysdeps/mips
git mv ports/sysdeps/unix/mips sysdeps/unix/mips
git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips

and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.mips similar to those in other files.

Tested that disassembly of installed shared libraries for mips is the
same before and after this patch (except for ld.so where paths in
assertions are involved, as for arm).

	* sysdeps/mips: Move directory from ports/sysdeps/mips.
	* sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips.

384b7b4309 Move shared umount.c from hppa to mips.
This patch prepares for moving mips from ports to libc by reversing
the #include ordering between mips and hppa.

Reversing #include ordering for umount.c is the conservative change in
preparation for moving the mips port.  In fact, it appears there are
several redundant umount.c files all implementing umount in terms of
the umount2 syscall; I've filed bug 16552 for eliminating that
redundancy properly.

Tested that disassembly of shared libraries for mips (o32, n32, n64)
is the same before and after this patch.

	* sysdeps/unix/sysv/linux/hppa/umount.c: Move to
	sysdeps/unix/sysv/linux/mips/mips64/umount.c and #include that
	file.

	* sysdeps/unix/sysv/linux/mips/mips64/umount.c: Move from
	sysdeps/unix/sysv/linux/hppa/umount.c instead of #include of that
	file.

87569616d2 Remove mips dependency on alpha.
This patch removes an unnecessary dependency of the mips port on alpha
by including a powerpc file directly where previously the mips file
included the alpha one which then included the powerpc one.

	* sysdeps/unix/sysv/linux/mips/ipc_priv.h: Directly include
	sysdeps/unix/sysv/linux/powerpc/ipc_priv.h instead of via
	sysdeps/unix/sysv/linux/alpha/ipc_priv.h.

4372980f58 Move tilegx, tilepro, and linux-generic from ports to libc.
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure.  Beyond the README
update, the move was just

    git mv ports/sysdeps/tile sysdeps/tile
    git mv ports/sysdeps/unix/sysv/linux/tile \
      sysdeps/unix/sysv/linux/tile
    git mv ports/sysdeps/unix/sysv/linux/generic \
      sysdeps/unix/sysv/linux/generic

I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d7 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.

c6bfe5c4d7 Move arm from ports to libc.
I've moved the ARM port from ports to the main sysdeps hierarchy.
Beyond the README update, the move of the files was simply

git mv ports/sysdeps/arm sysdeps/arm
git mv ports/sysdeps/unix/arm sysdeps/unix/arm
git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm

and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.arm similar to that at the top of
ChangeLog.powerpc.  There is deliberately no NEWS change, as I think
it makes the most sense to put in a general note above all ports
having moved if we can achieve that for 2.20.

Tested that disassembly of installed shared libraries for arm is the
same before and after this patch, except for data (not instructions)
in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the
path by which that file is found, and so by which it appears in the
assertion message, changes as a result of the move).

	* sysdeps/arm: Move directory from ports/sysdeps/arm.
	* sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm.
	* sysdeps/unix/sysv/linux/arm: Move directory from

852fa2dd3a Move shared sysdeps files from alpha to arm.
This patch prepares for moving arm from ports to libc (see overall
plan at <https://sourceware.org/ml/libc-alpha/2014-01/msg00373.html>
and discussion of ordering starting at
<https://sourceware.org/ml/libc-ports/2014-01/msg00071.html>) by
reversing the #include order between arm and alpha, so that arm can
move early as a test for the general pattern of moving architectures.
MicroBlaze files (that used the same alpha files) were made to include
the files directly from their new locations rather than indirecting.

Tested that disassembly of installed shared libraries for arm is the
same before and after this patch.

	* sysdeps/unix/sysv/linux/alpha/msgctl.c: Move to
	sysdeps/unix/sysv/linux/arm/msgctl.c and #include that file.
