We need something like static void __report_prefix_pop(void) { char *p, *q; if (!*prefixes) return; for (p = prefixes, q = strstr(p, PREFIX_DELIMITER) + 2; *q; p = q, q = strstr(p, PREFIX_DELIMITER) + 2) ; *p = '\0'; } void report_prefix_pop(void) { spin_lock(&lock); __report_prefix_pop(); spin_unlock(&lock); } void report_prefix_popn(int n) { spin_lock(&lock); while (n--) __report_prefix_pop(); spin_unlock(&lock); } > +} > + > +void report_prefix_clear(void) > +{ > + spin_lock(&lock); > + prefixes[0] = '\0'; > + spin_unlock(&lock); > +} I'm also second guessing the utility of this one. We'd probably almost never want to do this since most tests are designed with a main() { report_prefix_push("mytest"); subtest1(); subtest2(); ... report_prefix_pop(); ... } type pattern and we wouldn't want to lose that "mytest" prefix when some subtest calls clear. Let's just drop report_prefix_clear() for now. > + > static void va_report(const char *msg_fmt, > bool pass, bool xfail, bool kfail, bool skip, va_list va) > { > -- > 2.43.0 > Thanks, drew
Also, let's separate this patch into its own series where we also apply it with a second patch to the current riscv/sbi.c in order to remove a bunch of pops.
