--- Comment #7 from tomtab at gcc dot gnu.org --- Created attachment 40843 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40843&action=edit Generate a nop at the end of a looping memcpy This patch changes mips_block_move_loop to generate a nop insn at the end of the loop whenever the loop ends in a jump insn. The nop disappears during the cse1 pass, where it is removed through DCE.
