hi,
I am not sure how do deal with unwanted cflags(cxxflags), so I ask here :)
For kjs for example -ffast-math is known to cause problems, as we stricly rely
on IEEE compatible floating point, NaN, Inf, signed Zero and all the stuff.
So the question should I filter them? or leave it to the user to
optimize(break) his system?
If you say yes to filter, it also involves
-fno-math-errno
-funsafe-math-optimizations
-ffinite-math-only
-fno-rounding-math
-fno-signaling-nans
-fcx-limited-range
and I have no clue if there are msvc (or other compiler) versions of them.
If you are against filter, how should I deal with bugreport caused by XYZ
cflag?
