usesMSVCFloatingPoint()

static bool usesMSVCFloatingPoint ( const Triple &  TT, const Module &  M  )

static

True if this module is being built for windows/msvc, and uses floating point.

This is used to emit an undefined reference to _fltused. This is needed in Windows kernel or driver contexts to find and prevent code from modifying non-GPR registers.

TODO: It would be better if this was computed from MIR by looking for selected floating-point instructions.
