|
|
# 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.
