ldbl-128ibm-compat: Fix selection of GNU and ISO C99 scanf Since commit commit 03992356e6fedc5a5e9d32df96c1a2c79ea28a8f Author: Zack Weinberg <zackw@panix.com> Date: Sat Feb 10 11:58:35 2018 -0500 Use C99-compliant scanf under _GNU_SOURCE with modern compilers. the selection of the GNU versions of scanf functions requires both _GNU_SOURCE and -std=c89. This patch changes the tests in ldbl-128ibm-compat so that they actually test the GNU versions (without this change, the redirection to the ISO C99 version always happens, so GNU versions of the new implementation (e.g. __scanfieee128) were left untested). Tested for powerpc64le. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com> 2019-11-27 16:06:50 +00:00			`/* Include stdio.h from libio/, because include/stdio.h and -std=c89 do`

ldbl-128ibm-compat: Add wide character scanning functions Similarly to what was done for regular character scanning functions, this patch uses the new mode mask, SCANF_LDBL_USES_FLOAT128, in the 'mode' argument of the wide characters scanning function, __vfwscanf_internal (which is also extended to support scanning floating-point values with IEEE binary128, by redirecting calls to __wcstold_internal to __wcstof128_internal). Tested for powerpc64le. Reviewed-By: Paul E. Murphy <murphyp@linux.ibm.com> 2019-07-11 14:47:21 +00:00			`#define CHAR wchar_t`
ldbl-128ibm-compat: Add ISO C99 versions of scanf functions In the format string for *scanf functions, the '%as', '%aS', and '%a[]' modifiers behave differently depending on ISO C99 compatibility. When _GNU_SOURCE is defined and -std=c89 is passed to the compiler, these functions behave like ascanf, and the modifiers allocate memory for the output. Otherwise, the ISO C99 compliant version of these functions is used, and the modifiers consume a floating-point argument. This patch adds the IEEE binary128 variant of ISO C99 compliant functions for the third long double format on powerpc64le. Tested for powerpc64le. Reviewed-by: Paul E.
