- Subject: [RFA:] PR35293 and testsuite: don't run tests using truncation on targets without support
Here's the part of PR libfortran/35293 that stops targets without
truncation supports from running such tests. The test-cases are
semi-automatically edited from the truncation-specific failure messages
from cris-axis-linux-gnu (simulator complaining about lack of support at
the ftruncate64 syscall) and verified by regtesting for arm-elf and
cris-elf. No regressions for x86_64-unknown-linux-gnu and removes the old
and new (from previous patch) regressions for cris-elf and
cris-axis-linux-gnu. I checked that a simulator (i.e. not just a native
target) *with* ftruncate support would be flagged as having ftruncate
support by instrumenting enough to see cris-axis-linux-gnu pass
(i.e. using ftruncate rather than ftruncate64).
The feature name fd_truncate was chosen as not being the name of a syscall
or libc function but being the name of the function in
libgfortran/io/unix.c that's responsible for file truncation, using either
chsize or ftruncate as available (see previous message). It needs to be a
run-test rather than a link-test, as I can imagine (no promise on being
instrumental) in adding stub support for ftruncate to newlib, which would
cause a link-test to pass but the tests still fail.
An alternative would be to not build fortran or run the testsuite at all
for such targets, which might seem easier, but I recall finding one or two
target-related-fortran bugs by running the gfortran testsuite, so I'd like
to keep it running and to avoid the noise from tests with truncation. If
you worry about the maintenance burden, I plan to commit as obvious
henceforth adding fd_truncate gates as necessary whenever I see a new
failure or regression where gfortran.log shows a "Fortran runtime error:
required ftruncate or chsize support not present"; not very hard and
either way nobody worried about these failures for newlib targets before
so it's no big deal if they aren't fixed on commit for new tests.
