X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0c88d078eba7f51d2e5fc76a630f7eb369c09c87;p=gcc.git

Fix compile time warning about building the FRV backend by adding missing break statements to the switches in frv_register_move_cost.

	PR target/85978
	* config/frv/frv.c (frv_register_move_cost): Add break statements
	to avoid falling through to the wrong cases.  Tidy code.
