How to inline x64 asm in vs2017 ?

[Archer]

You have several options.
1. Switch to some other compiler like intel or GCC. You can still use Visual Studio, just a different compiler, they don't have inline asm restrictions.
2. Compile a separate .asm and link with other compiled .cpp files. This can be configured, so it's done automatically when the solution is built.
3. Sometimes it's enough to use intrinsics. But of course they don't cover all asm instructions.
