Konstantin Belousov c0b5fcf692 Improve FPU Tag Word reconstruction on i386 to indicate register states. ... Improve the code reconstructing en_tw in struct fpreg32 from FXSAVE results so that all register states are indicated correctly. The previous code unconditionally mapped non-empty register state to 'normalized value' constant. The new code explicitly distinguishes the 'zero value' and 'special value' constants as well. This improves consistency between real FSAVE and translation from FXSAVE, and ensures that tests using PT_GETFPREGS can rely on a single correct value independently of the underlying implementation.
