ISO C99 says it should be (inf, inf) always in G.5.1 (4): > "if the first operand is a nonzero finite number or an infinity and the second > operand is a zero, then the result of the / operator is an infinity." "is an infinity" allows (inf, NaN) and (NaN, inf), it doesn't require (inf, inf) (G.3#1: "A complex or imaginary value with at least one infinite part is regarded as an infinity (even if its other part is a NaN)."). Thus at least the testcase needs to change. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30360
