boolTARGET_CALL_FUSAGE_CONTAINS_NON_CALLEE_CLOBBERS ¶Set to true if each call that binds to a local definition explicitlyclobbers 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 thelinker (e.g. stubs, veneers, branch islands), but not including thosemodifiable by the callee. The affected registers may be mentioned explicitlyin 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 hookis to enable the fipa-ra optimization.
