line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:
(lldb) source list -f test.c -l1 -c222 -b
1 #include <stdio.h>
2 #include <sys/fcntl.h>
3 #include <unistd.h>
4 int
5 sleep_loop (const int num_secs)
[2] 6 {
7 int i;
[1] 8 for (i=0; i<num_secs; ++i)
9 {
[1] 10 printf("%d of %i - sleep(1);\n", i, num_secs);
[1] 11 sleep(1);
12 }
13 return 0;
[1] 14 }
15
16 int
17 main (int argc, char const* argv[])
[1] 18 {
[1] 19 printf("Process: %i\n\n", getpid());
[1] 20 puts("Press any key to continue..."); getchar();
[1] 21 sleep_loop (20);
22 return 12;
[1] 23 }
Above we can see there are two breakpoints for line 6 and one breakpoint for
lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table
entries for them. This helps visualize the data provided in the debug
information without having to manually dump all line tables. It also includes
all inline breakpoint that may result for a given file which can also be very
handy to see.
