# This test *must* be run prior to releasing any build of either stdenv or the
|

|
|
# gcc that it exports! This check should also be part of CI for any PR that

|
|
# causes a rebuild of `stdenv.cc`.

# When we used gcc's internal bootstrap it did this check as part of (and
|
||
|
|
# serially with) the gcc derivation. Now that we bootstrap externally this
|
||
|
|
# check can be done in parallel with any/all of stdenv's referrers. But we
|
||
|
|
# must remember to do the check.
