# For hard support: http://blog.alexrp.com/2014/02/18/android-hard-float-support/
# "First, to utilize the hard float ABI, you must either compile every last component of your application
# as hard float (the -mhard-float GCC/Clang switch), or mark individual functions with the appropriate
# __attribute__ to indicate the desired ABI. For example, to mark a function so that it’s called with the
# soft float ABI, stick __attribute__((pcs("aapcs"))) on it.
# Note that the NDK will link to a libm which uses the aforementioned attribute on all of its functions.
# This means that if you use libm functions a lot, you’re not likely to get much of a boost in those places.
# The way to fix this is to add -mhard-float -D_NDK_MATH_NO_SOFTFP=1 to your GCC/Clang command line. Then
# add -lm_hard to your linker command line (or -Wl,-lm_hard if you just invoke GCC/Clang to link). This will
# make your application link statically to a libm compiled for the hard float ABI. The only downside of this
# is that your application will increase somewhat in size."
