MaskRay added inline comments.


================
Comment at: libc/test/utils/FPUtil/x86_long_double_test.cpp:27
+    // then the number is a NaN for all values of mantissa.
+    bits.mantissa = i;
+    long double nan = bits;
----------------
You can test whether some combinations of bits are significant, instead of iterating over all integers from 0 to 1000000 (it is slow).
