When building Universal Ctags, some local variables in code
generated by packcc cause warnings:
peg/kotlin.c: In function ‘pcc_evaluate_rule_classParameter’:
peg/kotlin.c:3474:22: warning: unused variable ‘n’ [-Wunused-variable]
3474 | const size_t n = chunk->thunks.len;
| ^
peg/kotlin.c:3473:22: warning: unused variable ‘p’ [-Wunused-variable]
3473 | const size_t p = ctx->cur;
| ^

Why do you want to remove the compiler option |
As a developer of Universal ctags that uses code generated by packcc, removing unused local variables from the the generated code is enough. For my purpose, I defined MARKED_VAR_AS_USED. After adding it I found I could use the macro to suppress the warning related to -Wunused-parameter. I will withdraw this pull request and open a new one specialized in eliminating unused local variables. |
