Often we want to write tests cases that check things like bad context
offset accesses. And one way to do this is to use an odd offset on,
for example, a 32-bit load.
This unfortunately triggers the alignment checks first on platforms
that do not set CONFIG_EFFICIENT_UNALIGNED_ACCESS. So the te
On sparc64 a ton of test cases in test_verifier.c fail because
the memory accesses in the test case are unaligned (or cannot
be proven to be aligned by the verifier).
Perhaps we can eventually try to (carefully) modify each one
with this problem to not use unaligned accesses but:
1) That is del
Add F_LOAD_WITH_ANY_ALIGNMENT.
On architectures which are don't have efficient unaligned accesses,
this provides a way to force test cases to ignore alignment issues and
instead test the actual problem the testcase is targetting.
Only use this initially for programs where the expected result is
If a testcase has alignment problems but is expected to be ACCEPT,
verify it using F_LOAD_WITH_ANY_ALIGNMENT however to not try to
execute it.
In this way folks on inefficient unaligned access architectures
can more fully regression test the verifier.
