VFIXUPIMMPS

This instruction converts a specified immediate value to a floating-point format and stores the result in the destination. It is used to fix up floating-point constants by converting an immediate integer value into a floating-point representation of the target precision.

The following table covers what the source and destinations can be:

DO NOT support LOCK

This instruction is available only in 64-bit mode. It is not supported in compatibility mode.

To avoid precision loss or invalid operations, ensure the immediate value is within the representable range of the target floating-point format. Failure to align the immediate value with the destination register size (f32 vs f64) may result in unexpected truncation or casting behavior.
