asmjit::Environment Class Reference

Represents an environment, which is usually related to a Target.

Environment has usually an 'arch-subarch-vendor-os-abi' format, which is sometimes called "Triple" (historically it used to be 3 only parts) or "Tuple", which is a convention used by Debian Linux.

AsmJit doesn't support all possible combinations or architectures and ABIs, however, it models the environment similarly to other compilers for future extensibility.
