2019-07-10tests/tcg: fix diff-out pass to properly report failureAlex Bennée
A side effect of piping the output to head is squash the exit status of the diff command. Fix this by only doing the pipe if the diff failed and then ensuring the status is non-zero. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2019-07-10tests/tcg: fix up test-i386-fprem.ref generationAlex Bennée
We never shipped the reference data in the source tree because it's quite big (64M). As a result the only option is to generate it locally. Although we have a rule to generate the reference file we missed the dependency and location changes, probably because it's only run for SLOW test runs.
