Hi,

AFAICS the code in build_round_expr implicitly assumes that __float128 exists, 
which is *not* the common case among 64-bit architectures since "long double" 
is generally already 128-bit for them.

Tested on x86-64/Linux and SPARC64/Linux, OK for the mainline?

	* trans-intrinsic.c (build_round_expr): Do not implicitly assume
	that __float128 is the 128-bit floating-point type.
