When a function is inlined, the coverage result will not consider it was
called, and always report the coverage count as 0000000.
For example, the program:
int inlined(int p, int q) {
return p+q;
}
void main() {
inlined(1, 3);
}
without -inline, the coverage result is
|int inlined(int p, int q) {
1| return p+q;
|}
|void main() {
1| inlined(1, 3);
|}
x.d is 100% covered
with -inline, the 'inlined' function becomes uncovered
|int inlined(int p, int q) {
0000000| return p+q;
|}
|void main() {
1| inlined(1, 3);
|}
x.d is 50% covered

What kind of textual output do you desire in this situation?

http://d.puremagic.com/issues/show_bug.cgi?id=5848 --- Comment #4 from kennytm gmail.com 2011-04-17 00:50:20 PDT --- (In reply to comment #3)(In reply to comment #2)Ideally that line should display "1", like the 2nd piece of code I've shown in the first post. The coverage percent should be 100%, not 50%. Why would one expect to get 0000000 when a line of code is used? If it's not possible to get an exact count, at least it should show something other than 0000000, and count that line as covered. In gcov the equivalent program shows '1' in the corresponding line even with maximum optimization (-O3). So avoiding 0000000 in most of the cases should be possible. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------(In reply to comment #1)What coverage results textual file do you want DMD to save on disk about that inlined() function when you compile the program with the -inline switch too?What kind of textual output do you desire in this situation?What do you mean?

Please make sure you have the '-inline' flag. Test with 'dmd', not 'rdmd'.
