PureBasic don´t use FPU-instructions, it uses the msvcrt.dll (routines without FPU).

Re: SHA256 with CPU-SHA-Instruction-Set

Sorry, but if I install a new PB-version, first action is copy the latest FAsm-version into the PB Compilers-Directory.
SHA-support is new in FAsm-version 1.71.40 (Oct 19, 2015)! 2 years :D !
