commit bf7afdf34ad71b1e644dda34053e491653ca59e7

reproducible
|
|
|
|
Sort input file list so that mpich builds in a reproducible way
|
|
in spite of indeterministic filesystem readdir order
|
|
|
|
See https://reproducible-builds.org/ for why this is good.
|
|
|
|
Without this patch, README.envvar, /usr/lib64/mpi/gcc/mpich/bin/mpivars
|
|
and other output files varied between builds.
|
|
|
|
Signed-off-by: Nicolas Morey-Chaisemartin <nmoreychaisemartin@suse.com>
|
|
|
|
Also remove any unreproducible timestamps from generated files.
