TEMP: powerpc64le: Enable support for IEEE long double
DO NOT COMMIT!!!!!
<NEWS entry>
On platforms where long double may have two different formats, i.e.: the
same format as double (64-bits) or something else (128-bits), building
with -mlong-double-128 is the default and function calls in the user
program match the name of the function in Glibc. When building with
-mlong-double-64, Glibc installed headers redirect such calls to the
appropriate function.
This patch adds similar redirections to be used by builds in IEEE long
double mode (-mabi=ieeelongdouble). It also skips some uses of
libc_hidden_proto in internal headers, because they also produce
redirections, causing a redirection conflict.
Tested for powerpc64le.
* argp/argp.h: When in IEEE long double mode, include the header
that produces the redirections.

ldbl-128ibm-compat: Compiler flags for stdio functions
Some of the files that provide stdio.h and wchar.h functions have a
filename prefixed with 'io', such as 'iovsprintf.c'. On platforms that
imply ldbl-128ibm-compat, these files must be compiled with the flag
-mabi=ibmlongdouble. This patch adds this flag to their compilation.
Notice that this is not required for the other files that provide
similar functions, because filenames that are not prefixed with 'io'
have ldbl-128ibm-compat counterparts in the Makefile, which already adds
-mabi=ibmlongdouble to them.

Do not redirect calls to __GI_* symbols, when redirecting to *ieee128
On platforms where long double has IEEE binary128 format as a third
option (initially, only powerpc64le), many exported functions are
redirected to their __*ieee128 equivalents. This redirection is
provided by installed headers such as stdio-ldbl.h, and is supposed to
work correctly with user code.
However, during the build of glibc, similar redirections are employed,
in internal headers such as include/stdio.h, in order to avoid extra PLT
entries. These redirections conflict with the redirections to
__*ieee128, and must be avoided during the build. This patch protects
the second redirections with a test for __LONG_DOUBLE_USES_FLOAT128.
* include/err.h: Protect the redirection of warn, warnx, vwarn,
vwarnx, verr, and verrx)
* include/stdio.h: Likewise for __asprintf, fprintf, vfprintf,
sprintf, __snprintf, and sscanf.
* include/sys/syslog.h: Likewise for syslog and vsyslog.
* include/wchar.h: Likewise for vswscanf.

ldbl-128ibm-compat: Add syslog functions
I'm using 'syslog (LOG_DEBUG, etc.);' in the test case, which I believe
will not print to the console, but I'm not sure if changing some system
setting to high verbosity will disturb people's lives. Please advise.
:)
-- 8< --
Similarly to __vfprintf_internal and __vfscanf_internal, the internal
implementation of syslog functions (__vsyslog_internal) takes a
'mode_flags' parameter used to select the format of long double
parameters. This patch adds variants of the syslog functions that set
'mode_flags' to PRINTF_LDBL_USES_FLOAT128, thus enabling the correct
printing of long double values on powerpc64le, when long double has IEEE
binary128 format (-mabi=ieeelongdouble).
Tested for powerpc64le.

Similar to the functions from the *printf family, this patch adds

ldbl-128ibm-compat: Add ISO C99 versions of scanf functions
In the format string for *scanf functions, the '%as', '%aS', and '%a[]'
modifiers behave differently depending on ISO C99 compatibility and on
_GNU_SOURCE. When _GNU_SOURCE is not set and when in compatibility with
ISO C99, these modifiers consume a floating-point argument. Otherwise,
they behave like ascanf, and allocate memory for the output. This patch
adds the IEEE binary128 variant of these functions for the third long
double format on powerpc64le.

ldbl-128ibm-compat: Add regular character scanning functions
The 'mode' argument to __vfscanf_internal allows the selection of the
long double format for all long double arguments requested by the format
string. Currently, there are two possibilities: long double with the
same format as double or long double as something else. The 'something
else' format varies between architectures, and on powerpc64le, it means
IBM Extended Precision format.
In preparation for the third option of long double format on
powerpc64le, this patch uses the new mode mask,
SCANF_LDBL_USES_FLOAT128, which tells __vfscanf_internal to call
__strtof128_internal, instead of __strtold_internal, and save the output
into a _Float128 variable.

and long double types, to verify that the IEEE long double

ldbl-128ibm-compat: Add wide character, fortified printing functions
Similarly to what was done for the regular character, fortified printing
functions, this patch combines the mode masks PRINTF_LDBL_USES_FLOAT128
and PRINTF_FORTIFY to provide wide character versions of fortified
printf functions. It also adds two flavors of test cases: one that
explicitly calls the fortified functions, and another that reuses the
non-fortified test, but defining _FORTIFY_SOURCE as 2. The first
guarantees that the implementations are actually being tested
(independently of what's in bits/wchar2.h), whereas the second
guarantees that the redirections calls the correct function in the IBM

ldbl-128ibm-compat: Add regular character, fortified printing functions
Since the introduction of internal functions with explicit flags for the
printf family of functions, the 'mode' parameter can be used to select
which format long double parameters have (with the mode flags:
PRINTF_LDBL_IS_DBL and PRINTF_LDBL_USES_FLOAT128), as well as to select
whether to check for overflows (mode flag: PRINTF_FORTIFY).
This patch combines PRINTF_LDBL_USES_FLOAT128 and PRINTF_FORTIFY to
provide the IEEE binary128 version of printf-like function for platforms
where long double can take this format, in addition to the double format
and to some non-ieee format (currently, this means powerpc64le).
There are two flavors of test cases provided with this patch: one that
explicitly calls the fortified functions, for instance __asprintf_chk,
and another that reuses the non-fortified test, but defining
_FORTIFY_SOURCE as 2. The first guarantees that the implementations are
actually being tested (in bits/stdio2.h, vprintf gets redirected to
__vfprintf_chk, which would leave __vprintf_chk untested), whereas the
second guarantees that the redirections calls the correct function in
the IBM and IEEE long double cases.
Tested for powerpc64le.

ldbl-128ibm-compat: Add regular character printing functions
The 'mode' argument to __vfprintf_internal allows the selection of the
long double format for all long double arguments requested by the format
string. Currently, there are two possibilities: long double with the
same format as double or long double as something else. The 'something
else' format varies between architectures, and on powerpc64le, it means
IBM Extended Precision format.
In preparation for the third option of long double format on
powerpc64le, this patch uses the new mode mask,
PRINTF_LDBL_USES_FLOAT128, which tells __vfprintf_internal to save the
floating-point values into variables of type __float128 and adjusts the
parameters to __printf_fp and __printf_fphex as if it was a call from
strfromf128.
Tested for powerpc64le.
* elf/tst-addr1.c (do_test): Accept redirections of printf to
__printfieee128.
* sysdeps/ieee754/ldbl-128ibm-compat/Makefile:
[subdir == stdio-common] (ldbl-extra-routines): Add asprintf,
dprintf, fprintf, printf, snprintf, sprintf, vasprintf,
vdprintf, vfprintf, vprintf, vsnprintf, and vsprintf.
[subdir == stdio-common] (CFLAGS-vfprintf-internal.c): New
variable. Add -mfloat128 to the compilation of
vfprintf-internal.c, so that it gets support for the use of
__printf_fp and __printf_fphex with __float128 parameter.
[subdir == stdio-common] (tests-internal): Add
test-printf-ieee128 and test-printf-ibm128.
[subdir == stdio-common] (CFLAGS-test-printf-ieee128.c): New
variable to add the relevant -mabi flags to the compilation.
[subdir == stdio-common] (CFLAGS-test-printf-ibm128.c): Likewise.

ldbl-128ibm-compat: Add Makefile routine to control compiler options
Many files from the stdio-common, wcsmbs, argp, misc, and libio
directories will have IEEE binary128 counterparts. Setting the correct
compiler options to these files (original and counterparts) would
produce a large amount of repetitive Makefile rules. To avoid this
repetition, this patch adds a Makefile routine that iterates over the
files adding or removing the appropriate flags.
Currently, this mechanism only affects printf_size. Future commits will
use the mechanism for many more files.
* sysdeps/ieee754/ldbl-128ibm-compat/Makefile
[subdir == stdio-common] (routines): Move the addition of
printf_size to ldbl-extra-routines.
(ldbl-extra-routines): New variable.
(ldbl-ibm128-files): New variable.
(obj-suf-foreach): New routine.

Prepare vfprintf to use __printf_fp/__printf_fphex with float128 arg
Changes since v2:
- Fixed style error in `do { ... } while (0)' blocks.
- Zero-initialize args_value[cnt] with memset, rather than relying on
the `.pa_long_double' member being the largest of the members.
Changes since v1:
- Updated to the revised and integrated patches for __ldbl_is_dbl
removal, i.e.: the patches in the following thread:
<https://sourceware.org/ml/libc-alpha/2018-12/msg00186.html>.
- Added description for the PRINTF_LDBL_USES_FLOAT128 macro.
- Removed the LDBL_USES_FLOAT128 macro.
- Added `do { } while (0)' to the PARSE_FLOAT_VA_ARG_EXTENDED,
PARSE_FLOAT_VA_ARG, and SETUP_FLOAT128_INFO macros. Appended
expansions with `;', accordingly.

On powerpc64le, long double can currently take two formats: the same as
double (-mlong-double-64) or IBM Extended Precision (default with
-mlong-double-128 or explicitly with -mabi=ibmlongdouble). The internal
implementation of printf-like functions is aware of these possibilities
and properly parses floating-point values from the variable arguments,
before making calls to __printf_fp and __printf_fphex. These functions
are also aware of the format possibilities and know how to convert both
formats to string.
When library support for TS 18661-3 was added to glibc, __printf_fp and
__printf_fphex were extended with support for an additional type
(__float128/_Float128) with a different format (binary128). Now that
powerpc64le is getting support for its third long double format, and
taking into account that this format is the same as the format of
__float128/_Float128, this patch extends __vfprintf_internal to properly
call __printf_fp and __printf_fphex with this new format.
Tested for powerpc64le (with additional patches to actually enable the
use of these preparations) and for x86_64.
* libio/libioP.h (PRINTF_LDBL_USES_FLOAT128): New macro to be
used as a mask for the mode argument of __vfprintf_internal.
* stdio-common/printf-parse.h (printf_arg): New union member:
pa_float128.
* stdio-common/vfprintf-internal.c
(PARSE_FLOAT_VA_ARG_EXTENDED): New macro.
(PARSE_FLOAT_VA_ARG): Likewise.
(SETUP_FLOAT128_INFO): Likewise.
(process_arg): Use PARSE_FLOAT_VA_ARG_EXTENDED and
SETUP_FLOAT128_INFO.
[__HAVE_FLOAT128_UNLIKE_LDBL] (printf_positional): Write
floating-point value to the new union member, pa_float128.
(printf_positional): Zero-initialize args_value[cnt] with memset.
