re PR target/30652 (SSE expansion is missing for isinf() and other fpclassify functions)
PR target/30652
PR middle-end/20558
* builtins.c (expand_builtin_interclass_mathfn): Provide a
generic fallback for isinf.
* c-cppbuiltin.c (builtin_define_float_constants): Move FP max
calculation code ...
* real.c (get_max_float): ... to here.
* real.h (get_max_float): New.
testsuite:
* gcc.dg/pr28796-1.c: Add more cases.
* gcc.dg/pr28796-2.c: Likewise.
