crafcat7 opened a new pull request, #2470:
URL: https://github.com/apache/nuttx-apps/pull/2470
## Summary
Warnings have no impacton the program itelf.
The function implementation does not specify a return type, and is treated
as a void return value function during use, so it is ignored.
```
CC: icmpv6_ping.c dhrystone/v2.1/dhry_2.c:30:1: warning: return type
defaults to ‘int’ [-Wimplicit-int]
30 | Proc_6 (Enum_Val_Par, Enum_Ref_Par)
| ^~~~~~
2. The implementation of some functions is opposite to the calling position,
and the processing can be ignored dhrystone/v2.1/dhry_2.c:39:9: warning:
implicit declaration of function ‘Func_3’ [-Wimplicit-function-declaration]
39 | if (! Func_3 (Enum_Val_Par))
3. This function is called from dhry_2.c and void behavior is expected.
dhrystone/v2.1/dhry_2.c:30:1: warning: function declaration isn’t a prototype
[-Wstrict-prototypes]
30 | Proc_6 (Enum_Val_Par, Enum_Ref_Par)
4. In the old version of C language, if the function declaration return
value is not set, the default is void; in the new version, it is int, but in
dhrystone, these functions are called as void type functions by default.

None,it just fix dhrystone benchmark warning
## Testing
Local test pass
