Hi Jim, I found a breakpoint problem. Setting a breakpoint by address doesn't work if the process isn't running. I traced it back to r322348, "Fix Breakpoint::RemoveInvalidLocations to fix the exec testcase.", from January 11.
With ToT from a few days ago on x86_64 Linux, I get the address of main and set a breakpoint: (lldb) p main (int (*)(int, char **)) $0 = 0x0000000000400570 (lldb) b 0x400570 Breakpoint 1: address = 0x0000000000400570 I run, it launches and runs to completion: (lldb) r Process 20293 launched: '/usr2/tedwood/lldb_test/factlin' (x86_64) Factorial of 10 is 3628800 Process 20293 exited with status = 0 (0x00000000) Set a breakpoint by line, launch, and it stops: (lldb) b 19 Breakpoint 2: where = factlin`main + 22 at factorial.c:32, address = 0x0000000000400586 (lldb) r Process 20352 launched: '/usr2/tedwood/lldb_test/factlin' (x86_64) Process 20352 stopped * thread #1, name = 'factlin', stop reason = breakpoint 2.1 frame #0: 0x0000000000400586 factlin`main(argc=1, argv=0x00007fffffffe218) at factorial.c:32 29 } 30 */ 31 -> 32 base = 10; 33 34 printf("Factorial of %d is %d\n", base, factorial(base)); 35 return 0; Set the breakpoint by address while the process is running and run again. This time it stops at the new address breakpoint. (lldb) b 0x400570 Breakpoint 3: where = factlin`main at factorial.c:13, address = 0x0000000000400570 (lldb) r There is a running process, kill it and restart?: [Y/n] Process 20352 exited with status = 9 (0x00000009) Process 20366 launched: '/usr2/tedwood/lldb_test/factlin' (x86_64) Process 20366 stopped * thread #1, name = 'factlin', stop reason = breakpoint 3.1 frame #0: 0x0000000000400570 factlin`main(argc=<unavailable>, argv=<unavailable>) at factorial.c:13 10 } 11 12 int main(int argc, char **argv) -> 13 { 14 unsigned base; 15 16 /* Break list shows the first breakpoint as unresolved, and the third as resolved.
