This is part of a series to remove uses of for_each_rtx from the ports.
As with the first FR-V patch, we can find_all_hard_regs instead.
Tested by making sure there were no code changes for gcc.dg, gcc.c-torture
and g++.dg for frv-elf. OK to install?
Thanks,
Richard
gcc/
* config/frv/frv.c (frv_io_handle_use_1): Delete.
(frv_io_handle_use): Use find_all_hard_regs.
