In a project I'm reworking, there is a type
type Opcode is range 0 .. 79;
associated with values:
k_Load_Address : constant := 0;
k_Push_Value : constant := 1;
...
I'd like to define Opcode as an enumerated type:
type Opcode is (k_Load_Address, k_Push_Value, ...);
The problem is that there are, in some places in the legacy code, arithmetic operations on Opcode values (ouch!). Is there a tool able to list those operations for the custom type Opcode, other than defining Opcode as enumerated and let the compiler find the arithmetic operations to be removed? Probably it's what I'll do ultimately, but maybe such a detection could be useful in another context.
TIA

You could define your own "+" on Opcode, recompile in GPS, and then
"find all references" on "+". That should list it.
