<pre>When I look at the html report for z.c (instructions below) I see line 3 is
colored red, which is correct because that line is never executed. But I also
see red on the semicolons at the ends of lines 4 and 5, and the tabs at the
start of lines 4, 5 and 6, which doesn't make much sense.
To reproduce:
$ cat z.c
int f(int x) {
switch (x) {
case 1: x = 2; break;
case 2: x = 3; break;
case 3: x = 5; break;
case 4: x = 7; break;
}
return x;
}
int main() {
f(2);
f(3);
f(4);
return 0;
}
$ clang -fcoverage-mapping -fprofile-instr-generate z.c -o z
$ ./z
$ llvm-profdata merge default.profraw -o merged.profdata
$ llvm-cov show -instr-profile merged.profdata z -format html -output-dir out
$ xdg-open out/index.html
I'm using llvm and clang built from svn trunk r296323.</pre>
