| 26 /* Optabs are tables saying how to generate insn bodies | |
| 27 for various machine modes and numbers of operands. | |
| 28 Each optab applies to one operation. | |
| 29 | |
| 30 For example, add_optab applies to addition. | |
| 31 | |
| 32 The insn_code slot is the enum insn_code that says how to | |
| 33 generate an insn for this operation on a particular machine mode. | |
| 34 It is CODE_FOR_nothing if there is no such insn on the target machine. | |
| 35 | |
| 36 The `lib_call' slot is the name of the library function that | |
| 37 can be used to perform the operation. | |
