Build cmd/dist with Go 1.4. +2. Using dist, build Go 1.x compiler toolchain with Go 1.4. +3. Using dist, rebuild Go 1.x compiler toolchain with itself. +4. Using dist, build Go 1.x cmd/go (as go_bootstrap) with Go 1.x compiler toolchain. +5. Using go_bootstrap, build the remaining Go 1.x standard library and commands. + +NOTE: During the transition from the old C-based toolchain to the Go-based one, +step 2 also builds the parts of the toolchain written in C, and step 3 does not +recompile those. + +Because of backward compatibility, although the steps above say Go 1.4, +in practice any release ≥ Go 1.4 but < Go 1.x will work as the bootstrap base. + +See golang.org/s/go15bootstrap for more details. + +Compared to Go 1.4 and earlier, dist will also take over much of what used to +be done by make.bash/make.bat/make.rc and all of what used to be done by +run.bash/run.bat/run.rc, because it is nicer to implement that logic in Go +than in three different scripting languages simultaneously. |
