Commit Message

Gabriel F. T. Gomes June 21, 2018, 2:10 a.m. UTC
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).

Tested for powerpc64le.

	* sysdeps/ieee754/ldbl-128ibm-compat/Makefile:
	[subdir == stdio-common] (routines): Add ieee128-asprintf_chk,
	ieee128-dprintf_chk, ieee128-fprintf_chk, ieee128-printf_chk,
	ieee128-snprintf_chk, ieee128-sprintf_chk, ieee128-vasprintf_chk,
	ieee128-vdprintf_chk, ieee128-vfprintf_chk, ieee128-vprintf_chk,
	ieee128-vsnprintf_chk, and ieee128-vsprintf_chk.
	[subdir == stdio-common] (tests-internal): Add
	test-printf-chk-ieee128 and test-printf-chk-ibm128.
	[subdir == stdio-common] (CFLAGS-test-printf-chk-ieee128.c): New
	variable to add the relevant -mabi flags to the compilation.
	[subdir == stdio-common] (CFLAGS-test-printf-chk-ibm128.c): Likewise.
	[subdir == stdio-common && run-built-tests == yes]
	(tests-special): Add $(objpfx)test-printf-chk-ieee128.out, and
	$(objpfx)test-printf-chk-ibm128.out.
	[subdir == stdio-common] ($(objpfx)test-printf-chk-ieee128.out):
	New build and test rule.
	[subdir == stdio-common] ($(objpfx)test-printf-chk-ibm128.out):
