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