Why is nop insn has "mov_reg" type instead of "no_insn"?
Asked by
Cosmin-Gabriel Samoila
Hello,
I was recently looking on gcc/gcc/
I know that return string was initially "mov r8, r8" and changed to "nop" but the type remained as "mov_reg"
Is there any reason why we are keeping this type instead of "no_insn" and how is instruction scheduling affected by this change?
Thank you,
Cosmin
