From 1771a5cf0eb58b44adcd3d3fba12c4781a5015af Mon Sep 17 00:00:00 2001 From: "Gabriel F. T. Gomes" Date: Thu, 11 Jul 2019 11:46:51 -0300 Subject: ldbl-128ibm-compat: Add wide character printing functions 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. Reviewed-By: Paul E.
