commit 99ec0318a3e820a0fcf4fcea4d25669f11de835d
Author: Gabriel F. T. Gomes <gabrielftg@linux.ibm.com>
Date: Thu Aug 8 10:42:35 2019 -0300
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.
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.
Tested for powerpc64le.
* elf/tst-addr1.c (do_test): Accept redirections of printf to
__printfieee128.
* sysdeps/ieee754/ldbl-128ibm-compat/Makefile
[subdir == stdio-common] (routines): Move the addition of
printf_size to ldbl-extra-routines.
[subdir == stdio-common] (ldbl-extra-routines): New variable.
[subdir == stdio-common] (ldbl-ibm128-files): New variable.
[subdir == stdio-common] (obj-suf-foreach): New routine.
[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.
* sysdeps/ieee754/ldbl-128ibm-compat/Versions: (libc): Add
__asprintfieee128, __dprintfieee128, __fprintfieee128,
__printfieee128, __snprintfieee128, __sprintfieee128,
__vasprintfieee128, __vdprintfieee128, __vfprintfieee128,
__vprintfieee128, __vsnprintfieee128, and __vsprintfieee128.

ldbl-128ibm-compat: Add regular character printing functions
No changes since v1.
-- 8< --
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.
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.
Tested for powerpc64le.

commit 197108ae63b3c2173ba7476150759ecd6e065d4c
Author: Gabriel F. T. Gomes <gabrielftg@linux.ibm.com>
Date: Thu Aug 8 10:42:35 2019 -0300
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.
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.
Tested for powerpc64le.
