Hi Pan,
Sorry about that. It looks like there was difference between my local
machine and CI machine.
From the CI it looks like we're back to the failure list we had on friday.
I'll do some local testing to manually confirm this.
Thanks,
Patrick

Hi Patrick,
After some investigation and double confirm, I think the
gcc.dg/graphite/pr111878.c ice may have nothing to do
with the patches of revert series as it exists for quit a while. It may related
to below commit
2e7abd09621a4401d44f4513adf126bce4b4828b RISC-V: Block VLSmodes according to
TARGET_MAX_LMUL and BITS_PER_RISCV_VECTOR
Could you please help to double check about it *manually*? Here is my step(s)
for your reference and I will take care of this failure soon.

Thanks Patrick.
Turn out that the make report cannot tell the error like below and then the
graphite.exp test will never run.
That explains why I missed test failures, will take care of it ASAP.
sorry, unimplemented: Graphite loop optimizations cannot be used (isl is not
available)

This patch in particular does not cause any more regressions. It's one
of the other reverts from the weekend.

For future reference, the precommit does not do well with many unrelated
patches that are dependent on eachother.
In the future sending these as a series would allow precommit to
properly test them (as always you can see the testing results on
patchworks).
Thanks,
Patrick

Hi Pan,
I was running the testsuite for this and noticed an ICE scroll by when

I'll send the full list of new failures once the runs finish.

After we reverted below 2 commits, the reference to attr need some
adjustment as the group_overlap is no longer available.
* RISC-V: Robostify the W43, W86, W87 constraint enabled attribute
* RISC-V: Rename vconstraint into group_overlap
The below tests are passed for this patch.
* The rv64gcv fully regression tests.
