Subject: [PATCH] powerpc: Fix the compiler mode used with C++ when -mabi=ieeelongdouble
Date: Fri, 27 Apr 2018 17:12:00 -0000 [thread overview]
Message-ID: <20180427171150.28010-1-tuliom@linux.ibm.com> (raw)
When compiling C++ code with -mabi=ieeelongdouble, KCtype is
unavailable and TCtype should be used instead.
2018-04-27 Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
* sysdeps/powerpc/bits/floatn.h [__HAVE_FLOAT128
&& (!__GNUC_PREREQ (7, 0) || defined __cplusplus)
&& __LDBL_MANT_DIG__ == 113] (__cfloat128): Use compiler mode __TC__.
