Below is the explanation of "+race=all" in VCS help. But I can't completely understand it. Does it mean if don't use this option, the VCS will ignore the potential race in the source code? And if there's a real race exist in the source code, the VCS won't report it if No use the option "+race=all" when compile?
+race=all
Analyzes the source code during compilation to look for coding styles that cause race conditions.
It means if you use this option, vcs will attempt to find out your code that vcs thinks is irregular. It does not means that your code has something wrong. It only means your code does not match its coding standard.
