Title Body

Considering that I'm coding in C++, if possible, I would like to use an Intrinsics-like solution to read useful informations about the hardware, my concerns/considerations are: I don't know assembly that well, it will be a considerable investment just to get this kind of informations ( altough it looks like CPU it's just about flipping values and reading registers. ) there at least 2 popular syntax for asm ( Intel and AT&T ), so it's fragmented strangely enough Intrinsics are more popular and supported than asm code this days not all the the compilers that are in my radar right now support inline asm, MSVC 64 bit is one; I'm afraid that I will find other similar flaws while digging more into the feature sets of the different compilers that I have to use. considering the trand I think that is more productive for me to bet on Intrinsics, it should be also way more easy than any asm code. And the last question that I have to answer to is: how to do a similar thing with intrinsics ? Because I haven't found nothing other than CPUID opcodes to get this kind of informations at all.
