Bug ID: 34059
Summary: source-based code coverage shows coverage for
constants defined with #define
Product: new-bugs
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: efrie...@codeaurora.org
CC: llvm-bugs@lists.llvm.org, v...@apple.com
Consider the following:
#define VAL -1
int f(void) {
return VAL;
}
If you generate a coverage report, we show coverage for the code in f()... and
we also show coverage for "-1". I guess that's correct, in some sense, but it
isn't really useful; the user thinks of it as a constant, not code.
On its own, this doesn't matter much. But it gets annoying when you generate a
coverage report for a C codebase: the report includes a bunch of headers which
don't contain any code.
