You might be able to make a gimple testcase which starts right before expand.

The bug is that nothing calls ix86_fixup_binary_operands_no_copy on it.
Now, either we can call it in the new cond_ expander, or better follow what
other spots do and have just define_insn * with ix86_binary_operator_ok even
for the mask cases and add define_expand that calls
ix86_fixup_binary_operands_no_copy.

i386: Fix up cond_{and,ior,xor,mul}* [PR104779]
The following testcase ICEs, because the cond_andv* expander
has vector_operand predicates in both of the commutative inputs
and calls gen_andv*_mask which calls ix86_binary_operator_ok
in its condition, but nothing calls ix86_fixup_binary_operands_no_copy
during the expansion, which means cond_* accepts even operands
like 2 MEMs which then can't be matched.
The following patch handles it like most other insns that the other
cond_* patterns use - by having a separate define_expand that calls
ix86_fixup_binary_operands_no_copy and define_ins with
ix86_binary_operator_ok.
