[Vm-dev] FloatMathPlugin crash on 64-bit VM

[Nicolas Cellier]

Hi Levente,
I have forgotten where do we load the FloatMathPluginTests from?

Could it be related to:

fdlibm uses pointer aliasing, so special compiler flags are mandatory on
modern C compiler to make it work

Once I proposed simple changes to "fix" the library

Note that 64bits also require -D__LITTLE_ENDIAN flag on 64bits
