Commit Message

Gabriel F. T. Gomes June 21, 2018, 2:10 a.m. UTC
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:
	New file.
	* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-swprintf_chk.c:
	Likewise.
	* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vfwprintf_chk.c:
	Likewise.
	* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vswprintf_chk.c:
