Subject: tests: force non-deterministic mode in non-deterministic tests
X-Git-Tag: gdb-15-branchpoint~761
X-Git-Url: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff_plain;h=64e215c15bc316f673161c76db93a50bda45666a;hp=5790996072837620a8fd3756dda5138eb2f2781b
tests: force non-deterministic mode in non-deterministic tests
Since ar can be built defaulting to deterministic mode, tests which
expect non-deterministic behaviour need to explicitly set the U flag.
The non-deterministic member test expects SOURCE_DATE_EPOCH to not be
set; this documents that. Unconditionally unsetting the variable
causes issues in test infrastructure (which expects unsetenv to only
be called on variables which are already set).
