CompilerBackend

This enum is set by the compiler and communicates which compiler backend is used to produce machine code. Think carefully before deciding to observe this value. Nearly all code should be agnostic to the backend that implements the language. The use case to use this value is to work around problems with compiler implementations.

Avoid failing the compilation if the compiler backend does not match a whitelist of backends; rather one should detect that a known problem would occur in a blacklist of backends.

The enum is nonexhaustive so that alternate Zig language implementations may choose a number as their tag (please use a random number generator rather than a "cute" number) and codebases can interact with these values even if this upstream enum does not have a name for the number. Of course, upstream is happy to accept pull requests to add Zig implementations to this enum.

This data structure is part of the Zig language specification.
