It is necessary to declare two operations with name "jalr" (second one takes an implicit parameter rd), but translator says that it is impossible to declare two operations with identical names.
Updated by Alexander Kamkin about 10 years ago
There are two ways to solve the problem:
- You can declare two operations with different names with identical names in
format
. - You can ignore
jalr
with the implicit parameter (there is no such instruction in MIPS - it's just a syntax sugaring).
My suggestion is 2.
