After checking your provided example I agree my patch was wrong.

I agree that DW_OP_implicit_value should be correct after reverting my patch.

Yes, DW_OP_stack_value I probably fixed for my specific testcase accidentally.
It needs some different fix than the fix by me.  I am fine/prefer to even
revert that part assuming you apply some correct/new fix afterwards instead.

I am fine with either way, reverting just DWARF_VALUE_LITERAL or both.

I do everything based on real execution results and my fix (accidentally)
fixed the entry-values testcase for me on big-endian.
