Requires integer move instructions for floating-point values and disables certain floating-point load optimizations.
/Qsafe_fp_loads
Remarks
/Qsafe_fp_loads is only available in the compilers that target x86; it is not available in the compilers that target x64 or ARM.
/Qsafe_fp_loads forces the compiler to use integer move instructions instead of floating-point move instructions to move data between memory and MMX registers. This option also disables register load optimization for floating-point values that can be loaded in multiple control paths when the value may cause an exception on load—for example, a NaN value.
This option is overridden by /fp:except. /Qsafe_fp_loads specifies a subset of the compiler behavior that's specified by /fp:except.
/Qsafe_fp_loads is incompatible with /clr and /fp:fast. For more information about floating point compiler options, see /fp (Specify Floating-Point Behavior).
