Older GCC versions, and non-GNU compilers, can still be used to compile programs using the GNU C Library. +* Support is added, on powerpc64le, for interfaces supporting the _Float128 + type from ISO/IEC TS 18661-3:2015. Most of the interfaces are taken from + TS 18661-3. The type-generic macros in <math.h> support this type, but + those in <tgmath.h> do not. The GNU C Library now requires GCC 6.2 or + later to build for powerpc64le.
