[RFA] Minor improvement to coremark, avoid unconditional jump to return
gcc/
* cfgcleanup.cc (bb_is_just_return): No longer static.
* cfgcleanup.h (bb_is_just_return): Add prototype.
* cfgrtl.cc (fixup_reorder_chain): Do not create an
unconditional jump to a return block. Conditionally
remove unreachable blocks.
gcc/testsuite/
* gcc.target/riscv/ret-1.c: New test.
