The assert in question fires if the pass creates an instruction
whose pattern uses a register or memory and if the pass doesn't
provide associated use information. Let me know if it looks like
a bug in rtl-ssa rather than a bug in the vsetvl pass.

Hi, it seems that your attatchment is an excution file instead of
a source code. It may not be easy for us to debug it.
Can you give me the source code? Thanks.

Just sync with juzhe for the assertion failure. It tries to find the regno=8 in
the shared_uses=[0, 66, 67] in function_info::finalize_new_accesses. And then
it will hit the NOT_NULL assert.
While in the pass_vsetvl::cleanup_insns, it will clean up the AVL use similar
as below.
AVL regno 8
Before Uses Reg Nums => [0,8,66,67,]
After Uses Reg Nums => [0,66,67,]
After vsetvl, the avl-related use, aka use Regno=8 will be removed, because the
instruction pattern in RVV will eliminate the dependencies of the operand.
Juzhe can help to correct me if any misleading or misunderstanding.
Thanks.

Hi, Richard.
As Li Pan said, the vsetvl pass is trying to remove regno = 8 in
old uses = [0,8,66,67,]
Here is the code:
access_array_builder uses_builder (attempt);
uses_builder.reserve (insn->num_uses () - 1);
for (use_info *use : insn->uses ())
if (use != find_access (insn->uses (), REGNO (avl)))
uses_builder.quick_push (use);
use_array new_uses = use_array (uses_builder.finish ());
change.new_uses = new_uses;
You can see here, I add all uses except the use which has the same regno with
"avl".
Am I using RTL_SSA in a wrong way ? Or I should remove RTL_SSA updating when
removing operands of uses ?
Looking forward your suggestions.
Thanks.

Can you quote a dump of the new insn pattern? Or just:
dump(change);
in function_info::finalize_new_accesses should do.

Confirm it is VSETVL pass bug in RISC-V port backend.

Hopefully, it will be merged soon.

Technically you are supposed to simply remove the keyword '14' from the title
