	45	### Supported Targets
	46
	47	#### Tier 1 Support
	48
	49	* Not only can Zig generate machine code for these targets, but the standard
	50	library cross-platform abstractions have implementations for these targets.
	51	Thus it is practical to write a pure Zig application with no dependency on
	52	libc.
	53	* The CI server automatically tests these targets on every commit to master
	54	branch, and updates ziglang.org/download with links to pre-built binaries.
	55	* These targets have debug info capabilities and therefore produce stack
	56	traces on failed assertions.
	57
	58	#### Tier 2 Support
	59
	60	* There may be some standard library implementations, but many abstractions
	61	will give an "Unsupported OS" compile error. One can link with libc or other
	62	libraries to fill in the gaps in the standard library.
	63	* These targets are known to work, but are not automatically tested, so there
	64	are occasional regressions.
	65	* Some tests may be disabled for these targets as we work toward Tier 1
	66	support.
	67
	68	#### Tier 3 Support
	69
	70	* The standard library has little to no knowledge of the existence of this
	71	target.
	72	* Because Zig is based on LLVM, it has the capability to build for these
	73	targets, and LLVM has the target enabled by default.
	74	* These targets are not frequently tested; one will likely need to contribute
	75	to Zig in order to build for these targets.
	76	* The Zig compiler might need to be updated with a few things such as
	77	- what sizes are the C integer types
	78	- C ABI calling convention for this target
	79	- bootstrap code and default panic handler
	80
	81	#### Tier 4 Support
	82
	83	* Support for these targets is entirely experimental.
	84	* LLVM may have the target as an experimental target, which means that you
	85	need to use Zig-provided binaries for the target to be available, or
	86	build LLVM from source with special configure flags.
