  11 # An explanation of how the build is structured:
  12 #
  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.
  19 #
  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.
  24 #
  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
  28 # architectures.
  29 #
  30 # The directory layout for a stage is intended to match the layout
  31 # of the installed compiler, and looks like the following:
  32 #
  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 #     rustc - rustc's own place to organize libraries
  37 #       $(target) - target-specific artifacts
  38 #         bin - binaries for target architectures
  39 #         lib - libraries for target architectures
  40 #
  41 # A note about host libraries:
  42 #
  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.
  49 #
  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.
  52 #
  53 # Admittedly this is a little convoluted.
