For 8-bit and 16-bit sign-extention mov instructions, it can use the native instructions ext.w.b and ext.w.h directly, no need to use the temporary t1 register, just remove the redundant operations. Here are the test results: # modprobe test_bpf test_range=81,84 # dmesg -t | tail -5 test_bpf: #81 ALU_MOVSX | BPF_B jited:1 5 PASS test_bpf: #82 ALU_MOVSX | BPF_H jited:1 5 PASS test_bpf: #83 ALU64_MOVSX | BPF_B jited:1 5 PASS test_bpf: #84 ALU64_MOVSX | BPF_H jited:1 5 PASS test_bpf: Summary: 4 PASSED, 0 FAILED, [4/4 JIT'ed] Acked-by: Hengqi Chen <[email protected]> Signed-off-by: Tiezhu Yang <[email protected]> Signed-off-by: Huacai Chen <[email protected]>
