GCC does not have an option called -Os2 .
Comment 5 Zhengfeng Zhu 2023-04-25 03:06:28 UTC 
OK. Thanks. Let me confirm this issue.
Comment 6 Richard Biener 2023-04-25 06:34:47 UTC 
Also note that GCC 7.3.0 which you report against is no longer supported.  The oldest compiler still receiving patches is GCC 10.4.  You can also try GCC 7.5.0, the last release from the GCC 7 branch.
Comment 7 Zhengfeng Zhu 2023-04-25 07:16:15 UTC 
OK. Thanks.
