| <dd><p>Set to true if each call that binds to a local definition explicitly |
| clobbers or sets all non-fixed registers modified by performing the call. |
| That is, by the call pattern itself, or by code that might be inserted by the |
| linker (e.g. stubs, veneers, branch islands), but not including those |
| modifiable by the callee. The affected registers may be mentioned explicitly |
| in the call pattern, or included as clobbers in CALL_INSN_FUNCTION_USAGE. |
| The default version of this hook is set to false. The purpose of this hook |
| is to enable the fipa-ra optimization. |
