Arch | target_arch : Target CPU architecture
|
Env | target_env : Target enviroment that disambiguates the target platform by ABI / libc.
This value is closely related to the fourth element of the platform target triple,
though it is not identical. For example, embedded ABIs such as gnueabihf will simply
define target_env as "gnu" (i.e. target::Env::GNU )
|
OS | target_os : Operating system of the target. This value is closely related to the second
and third element of the platform target triple, though it is not identical.
