parallel makes (make -jN) are indeterminate
|Assignee:||Eric Blossom||% Done:||
parallel makes run multiple copies of generate_all.py.The generate_all.py pattern used in
misbehaves under parallel makes resulting in races that make the outcome of the
make indeterminate. This is particularly noticeable when the build tree is
located on NFS. The problem was first noticed doing cell cross-compilations. The cross-compilation was a red herring. The triggering condition was that the build tree was on NFS.
