# Go has a number of supplementary tools and packages that are located in
# separate archives or source repositories. Because Go currently forces a
# recompile of all packages whenever the compiler changes, building and
# delivering them within the same build component build process is the best
# option for now.
# The long-term plan for packaging Go is roughly as follows:
#
# - when SPARC support is integrated into Go upstream, build upstream version
# using system Go for x86, then build Go for SPARC using upstream version
# just built for x86 (cross-compilation), package both at the same time
# - after SPARC version has been available for at least a few builds in the
# WOS, switch to building Go with system version for x86 and SPARC
#
# Supplementary packages; these are delivered as source only for now as the
# paths to the compiled packages are written directly into the binaries and
# there's no way (currently) to fix that during the build process.

# revisions chosen from the last commit to the respective repository at the
# same time that this component was updated as there is no formal release
# process for these packages. Whenever Go is updated, these should be as well.
# Resulting hash of related git commit once archived.
# Go package imports for lint are found in github directory.
# Go's "not well-formed" elf objects confuse elfsign, which then causes
# problems for RE. For now, we workaround this by adding the
# 'com.oracle.elfsign=false' tag to every elf object.
# We're x86-only for now.
