/* Optabs are tables saying how to generate insn bodies

for various machine modes and numbers of operands.
|
|
|

Each optab applies to one operation.
|
|
|
|
|
For example, add_optab applies to addition.
|
|
|
|
|
|
|
|
|
|
The insn_code slot is the enum insn_code that says how to

|
|
generate an insn for this operation on a particular machine mode.
|
|
|
|
|
It is CODE_FOR_nothing if there is no such insn on the target machine.

The `lib_call' slot is the name of the library function that

|
|
can be used to perform the operation.
|

|
