[PATCH 07/14] ldbl-128ibm-compat: Add wide character, fortified 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 23:10:16 -0300
- Subject: [PATCH 07/14] ldbl-128ibm-compat: Add wide character, fortified printing functions
- References: <20180621021023.17036-1-gabriel@inconstante.eti.br>
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.
Tested for powerpc64le.
* sysdeps/ieee754/ldbl-128ibm-compat/Makefile:
[subdir == stdio-common] (routines): Add ieee128-fwprintf_chk,
ieee128-swprintf_chk, ieee128-wprintf_chk,
ieee128-vfwprintf_chk, ieee128-vswprintf_chk, and
ieee128-vwprintf_chk.
[subdir == stdio-common] (tests-internal): Add
test-wprintf-chk-ieee128 and test-wprintf-chk-ibm128.
[subdir == stdio-common] (CFLAGS-test-wprintf-chk-ieee128.c): New
variable to add the relevant -mabi flags to the compilation.
[subdir == stdio-common] (CFLAGS-test-wprintf-chk-ibm128.c): Likewise.
[subdir == stdio-common && run-built-tests == yes]
(tests-special): Add $(objpfx)test-wprintf-chk-ieee128.out, and
$(objpfx)test-wprintf-chk-ibm128.out.
[subdir == stdio-common] ($(objpfx)test-wprintf-chk-ieee128.out):
New build and test rule.
[subdir == stdio-common] ($(objpfx)test-wprintf-chk-ibm128.out):
Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/Versions (libc): Add
__fwprintf_chkieee128, __swprintf_chkieee128,
__wprintf_chkieee128, __vfwprintf_chkieee128,
__vswprintf_chkieee128, and __vwprintf_chkieee128;
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-fwprintf_chk.c:
