6# Usage: buildall.bash [-e] [pattern]
7#
8# buildall.bash builds the standard library for all Go-supported
9# architectures.
10#
11# Originally the Go build system used it as a smoke test to quickly
12# flag portability issues in builders named "misc-compile" or "all-compile".
13# As of CL 464955, the build system uses make.bash -compile-only instead,
14# so this script no longer runs in any automated fashion.
15#
16# Options:
17#   -e: stop at first failure
