- # An explanation of how the build is structured:
- #
- # There are multiple build stages (0-3) needed to verify that the
- # compiler is properly self-hosting. Each stage is divided between
- # 'host' artifacts and 'target' artifacts, where the stageN host
- # compiler builds artifacts for 1 or more stageN target architectures.
- # Once the stageN target compiler has been built for the host
- # architecture it is promoted (copied) to a stageN+1 host artifact.
- #
- # The stage3 host compiler is a compiler that successfully builds
- # itself and should (in theory) be bitwise identical to the stage2
- # host compiler. The process is bootstrapped using a stage0 host
- # compiler downloaded from a previous snapshot.
- #
- # At no time should stageN artifacts be interacting with artifacts
- # from other stages. For consistency, we use the 'promotion' logic
- # for all artifacts, even those that don't make sense on non-host
- # architectures.
- #
- # The directory layout for a stage is intended to match the layout
- # of the installed compiler, and looks like the following:
- #
- # stageN - this is the system root, corresponding to, e.g. /usr
- # bin - binaries compiled for the host
- # lib - libraries used by the host compiler
- # rustc - rustc's own place to organize libraries
- # $(target) - target-specific artifacts
- # bin - binaries for target architectures
- # lib - libraries for target architectures
- #
- # A note about host libraries:
- #
- # The only libraries that get promoted to stageN/lib are those needed
- # by rustc. In general, rust programs, even those compiled for the
- # host architecture will use libraries from the target
- # directories. This gives rust some freedom to experiment with how
- # libraries are managed and versioned without polluting the common
- # areas of the filesystem.
- #
- # General rust binaries may stil live in the host bin directory; they
- # will just link against the libraries in the target lib directory.
- #
- # Admittedly this is a little convoluted.
