[PATCH 05/14] ldbl-128ibm-compat: Add wide character printing functions
- From: "Gabriel F. T. Gomes" <gabriel at inconstante dot eti dot br>
- To: <libc-alpha at sourceware dot org>
- Date: Wed, 20 Jun 2018 23:10:14 -0300
- Subject: [PATCH 05/14] ldbl-128ibm-compat: Add wide character printing functions
- References: <20180621021023.17036-1-gabriel@inconstante.eti.br>
Similarly to what was done for regular character printing functions,
this patch uses the new mode mask, PRINTF_LDBL_USES_FLOAT128, in the
'mode' argument of the wide characters printing function,
__vfwprintf_internal (which is also extended to support printing
floating-point values with IEEE binary128, by saving floating-point
values into variables of type __float128 and adjusting the parameters to
__printf_fp and __printf_fphex as if it was a call from a wide-character
version of strfromf128 (even though such version does not exist)).
Tested for powerpc64le.
* sysdeps/ieee754/ldbl-128ibm-compat/Makefile:
[subdir == stdio-common] (routines): Add ieee128-fwprintf,
ieee128-swprintf, ieee128-wprintf, ieee128-vfwprintf,
ieee128-vswprintf, and ieee128-vwprintf.
[subdir == stdio-common] (CFLAGS-vfwprintf-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-wprintf-ieee128 and test-wprintf-ibm128.
[subdir == stdio-common] (CFLAGS-test-wprintf-ieee128.c): New
variable to add the relevant -mabi flags to the compilation.
[subdir == stdio-common] (CFLAGS-test-wprintf-ibm128.c): Likewise.
[subdir == stdio-common && run-built-tests == yes]
(tests-special): Add $(objpfx)test-wprintf-ieee128.out and
$(objpfx)test-wprintf-ibm128.out.
[subdir == stdio-common] ($(objpfx)test-wprintf-ieee128.out):
New build and test rule.
[subdir == stdio-common] ($(objpfx)test-wprintf-ibm128.out):
Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/Versions (libc): Add
__fwprintfieee128, __swprintfieee128, __wprintfieee128,
__vfwprintfieee128, __vswprintfieee128, and __vwprintfieee128.
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-fwprintf.c: New file.
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-swprintf.c: Likewise.
