...ication thing - this sounds interesting. Correct me if I am wrong, but x86 CPUs have biult in protection via paging and ring modes, therefore application cannot change its page in memory therefore cannot interfere with another app other than using OS API. But does this feature have ARM CPUs? I actua...
_csv.Error: field larger than field limit (131072)
...ue is a C long ([Wikipedia]: C data types), whose size varies depending on CPU architecture and OS (ILP). The classical difference: for a 64bit OS (Python build), the long type size (in bits) is:
Nix: 64
Win: 32
When attempting to set it, the new value is checked to be in the long boundaries, th...
Why do x86-64 instructions on 32-bit registers zero the upper part of the full 64-bit register?
... the high half doesn't create a dependency on the previous value, that the CPU would have to wait on. The register renaming mechanism would essentially be defeated if it wasn't done that way.
This way you can write fast code using 32-bit values in 64-bit mode without having to explicitly break depe...
