I do some test of sanitize coverage with libfuzzer
as http://releases.llvm.org/4.0.0/tools/clang/docs/SanitizerCoverage.html
I know lightgreen is covered ,lightcoral is not-covered, navajowhite is
partially-covered
However , I still got confused when look the report like this :
How can the line 16 get covered with line 15 not covered?
Do I make some mistake?
1 int ueventStrLen = 0;
2
3 do {
4 PlatformDependent* platform = Config::GetPlatform();
5 if (!platform) {
6 LOGW("platform is null ptr.");
7 break;
8 }
9 IAccelerator* acc = platform->getAccelerator();
10 if (!acc) {
11 LOGW("acc is null ptr.");
12 break;
13 }
14 ueventStrLen = acc->getUeventNextEvent(ueventParam,
(int)sizeof(ueventParam) - 2);
15 if (ueventStrLen > 0) {
16 if (platform->handleUevent(&ctx->Callbacks, ueventParam,
ueventStrLen)) {
17 ctx->global_comp_info.settingChanged = true;
18 }
19 }
20 } while(ctx && !ctx->uevent_thread_exit);
