[Bug libstdc++/39491] [4.4/4.5 regression] symbol __signbitl@GLIBCXX_3.4 in libstdc++ not exported anymore
------- Comment #11 from carlos at codesourcery dot com 2009-04-21 20:16 -------
Yes, if gcc does not determine that "sizeof (x) == sizeof (double)" then it
would have to emit code for the if-then-else statement and this would create a
reference to an undefined __signbitl. Has this ever happened? I've never seen
At present glibc does not create an long double alias for the double __signbit
function, but for the sake of correctness it probably should.
