__need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more
complicated; the basic deal is that sys/uio.h wants to define a
constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a
constant named IOV_MAX, with the same meaning. For no apparent reason
this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed
to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on
Linux was being used as a dumping ground for extension functions.
So now we have bits/uio_lim.h, which defines __IOV_MAX.
bits/xopen_lim.h and sys/uio.h use that to define their respective
constants. We also now have bits/uio-ext.h, which is the official
Proper Home for extensions to sys/uio.h. bits/uio.h is removed, and
stdio_lim.h doesn't define IOV_MAX at all.
* bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h
* bits/uio-ext.h, sysdeps/unix/sysv/linux/bits/uio-ext.h: New file.
* bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file.
* include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value
for IOV_MAX.
* misc/Makefile: Install bits/uio-ext.h and bits/uio_lim.h.
Don't install bits/uio.h.
* misc/sys/uio.h: Don't include bits/uio.h. Do include
bits/types/struct_iovec.h and bits/uio_lim.h. Set UIO_MAXIOV
based on __IOV_MAX. Under __USE_GNU, also include bits/uio-ext.h.
* stdio-common/stdio_lim.h.in: Remove logic for __need_FOPEN_MAX
and __need_IOV_MAX. Don't define IOV_MAX at all.
* Makerules (stdio_lim.h): Remove logic for setting IOV_MAX.
* sysdeps/unix/sysv/linux/bits/fcntl-linux.h:
Include bits/types/struct_iovec.h, not bits/uio.h.
Use __ssize_t, not ssize_t, in function prototypes.
Don't use hard TAB for double space after period in comments.

ELFv2 functions with localentry:0 are those with a single entry point,
ie. global entry == local entry, that have no requirement on r2 or
r12 and guarantee r2 is unchanged on return. Such an external
function can be called via the PLT without saving r2 or restoring it
on return, avoiding a common load-hit-store for small functions.
This patch implements the ld.so changes necessary for this
optimization. ld.so needs to check that an optimized plt call
sequence is in fact calling a function implemented with localentry:0,
end emit a fatal error otherwise.
The elf/testobj6.c change is to stop "error while loading shared
libraries: expected localentry:0 `preload'" when running
elf/preloadtest, which we'd get otherwise.

A number of functions in the sysdeps/powerpc/powerpc64/ tree don't use

.align on some targets takes a byte alignment, on others like powerpc,
log2 of the byte alignment. It's a good idea to avoid .align,
particularly since x86 and powerpc are different. This patch fixes
the occurrences of .align in powerpc64/sysdep.h, renames DOT_LABEL
since the macro doesn't have anything to do with adding dots, removes
extraneous semicolons, and fixes some formatting.
* sysdeps/powerpc/powerpc64/sysdep.h: Formatting.
(FUNC_LABEL): Rename from DOT_LABEL.
(ENTRY_1): Use FUNC_LABEL and remove leading space from label.
Use .p2align rather than .align.

General purpose registers in mcontext_t structure
are 8 bytes long for both MIPS32/MIPS64.
get/set/make/swap context implementations for MIPS O32

<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from

bits/sched.h has logic to expose only an impl-namespace variant of
struct sched_param (i.e. struct __sched_param), but nothing uses it,
and the only header that includes bits/sched.h is sched.h. The
__need_schedparam logic can therefore be removed.
bits/sched.h also has a great deal of code relating to cpu_set_t
objects that was *almost* the same between the two versions of
bits/sched.h in the tree; a little spelunking indicated that this is
because some bug fixes got applied to the Linux-specific bits/sched.h
but not the generic one. Introduce a new header, bits/cpu-set.h,
containing the version of that code with the bugfixes, have sched.h
include it directly, and delete all of the code from both versions of
bits/sched.h.
Also remove the unnecessary name mangling in the definition of struct
sched_param -- POSIX specifies a field 'sched_priority', so there is
no reason to define it as '__sched_priority' and then paper over that
with a macro. (Just in case someone was using the internal name,
'sched_priority' remains a macro defined to expand to itself, and
'__sched_priority' now expands to 'sched_priority'.)
Finally, as long as I'm touching these files anyway, merge new
constants from linux/sched.h into the Linux bits/sched.h.
* bits/sched.h: Remove __need_schedparam logic and replace with a
normal multiple-include guard. Change field name in struct
sched_param from __sched_priority to sched_priority. Delete
everything under #ifndef __cpu_set_t_defined.
* sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with
kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants.
* posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h.
For compatibility, #define sched_priority to itself, and #define
__sched_priority as sched_priority.
* posix/bits/cpu-set.h: New file containing, verbatim, the code
that was under #ifndef __cpu_set_t_defined in
sysdeps/unix/sysv/linux/bits/sched.h.

TS 18661-3 specifies that macros prefixed with FLTN_ can be defined in
float.h, only if __STDC_WANT_IEC_60559_TYPES_EXT__ is defined as a macro
before the inclusion of float.h. Since GCC 7.0, these macros are provided
under this condition, however, for older versions of GCC, these macros are
not provided at all. This patch allows the definitions of such macros in
include/float.h for older compilers, if the condition above is met, and
even if _ISOMAC is defined.

bsd_signal was added in XPG4.2, so should be declared for
__USE_XOPEN_EXTENDED, instead of the present __USE_XOPEN condition.
This patch fixes the condition accordingly.

sigwait was added to POSIX in 1995; it is not in older POSIX versions
or XPG4 / XPG4.2. Thus it should be declared only if
__USE_POSIX199506; signal.h wrongly declares it for __USE_POSIX.
(sigwaitinfo is correctly conditioned on __USE_POSIX199309.) This
patch fixes the condition on the declaration of sigwait.
Tested for x86_64. Because of other namespace problems this does not
allow any conform/ XFAILs to be removed.

Implement strcpy family IFUNC selectors in C.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcpy family functions within libc.

There is currently no "cross-platform" (x86 and POWER) support for
determining the cacheline size.
This patch adds support to sysconf() to correctly report cacheline sizes
based on the information in the auxilliary vector.
Thus, using sysconf() is a cross-platform (x86 and POWER) solution for
determining cacheline sizes.
Support is added (on powerpc) for:
_SC_LEVEL1_ICACHE_SIZE _SC_LEVEL1_ICACHE_ASSOC _SC_LEVEL1_ICACHE_LINESIZE
_SC_LEVEL1_DCACHE_SIZE _SC_LEVEL1_DCACHE_ASSOC _SC_LEVEL1_DCACHE_LINESIZE
_SC_LEVEL2_CACHE_SIZE _SC_LEVEL2_CACHE_ASSOC _SC_LEVEL2_CACHE_LINESIZE
_SC_LEVEL3_CACHE_SIZE _SC_LEVEL3_CACHE_ASSOC _SC_LEVEL3_CACHE_LINESIZE
* sysdeps/unix/sysv/linux/powerpc/sysconf.c: New file.
Add powerpc-specific overrides for L1, L2, L3 CACHE_SIZEs,
CACHE_ASSOCs, and CACHE_LINESIZEs, retrieving from auxv.
* sysdeps/unix/sysv/linux/powerpc/test-powerpc-linux-sysconf.c:
New file. Invoke newly supported sysconf values for powerpc,
and report results. If none are supported, report so.

In sys/wait.h, waitid and associated constants and types are UX-shaded
in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so
should be appropriately conditional in the headers. This patch fixes
the conditionals accordingly. (WCONTINUED is actually still
XSI-shaded in POSIX.1:2008, but W* is also reserved there without
XSI-shading, so nothing special needs to be done about the
conditionals on WCONTINUED to conform to POSIX.1:2008 namespace
rules.)

A recent GCC change to expand floating-point classification built-in
functions inline using integer rather than floating-point arithmetic
in some cases resulted in localplt test failures for nios2 and sparc32
<https://sourceware.org/ml/libc-testresults/2017-q2/msg00320.html>.
This patch updates the localplt.data files in question to mark the
relevant symbols as optional / add a new optional symbol. (The GCC
patch has been reverted because of other problems it caused, but one
can assume it will be applied again, without changes that would affect
the PLT entries generated, once those issues have been resolved.)

sys/wait.h includes signal.h unconditionally. But the permission to
do so is UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so
this should not be unconditional. This patch fixes this
conservatively: the include is kept, but conditioned on the standards
that permit it (meaning it is still present by default, because
non-XSI POSIX.1:2008 is enabled by default). <bits/types.h> is now
included unconditionally to provide the required definition of
__pid_t; it was previously included via <signal.h>. Some standards
require pid_t to be defined here, and all allow it to be defined here;
previously defined via <signal.h>, it's now defined directly in this
header.
Tested for x86_64. This does not fix any of the sys/wait.h
conformtest failures, but substantially reduces the number of
namespace failures for sys/wait.h for XPG4 and POSIX.
[BZ #21560]
* posix/sys/wait.h: Condition include of <signal.h> on

Like basically all before-compile headers, dl-tunable-list.h should be

addition to common-generated.

This patch corrects the conformtest expectations for sys/wait.h for
XPG4. This does not change the test results for this header at the
makefile level since it fixes some spurious failures for this header
while introducing other failures previously hidden by incorrect
expectations. However, it shows up issues with stdlib.h for XPG4
defining W* names that are not permitted in this case (previously
wrongly allowed; the W* reservation is UX-shaded in XPG4.2 /
XSI-shaded in POSIX before 2008); that test is thus XFAILed.
