Bug ID: 211516
Summary: lldb: single stepping does not work on arm
Product: Base System
Version: CURRENT
Hardware: arm
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-bugs at FreeBSD.org
Reporter: emaste at freebsd.org
Testing lldb in head on FreeBSD/arm shows that breakpoints work as expected,
but single stepping does not.
root@:~ # lldb --version
lldb version 3.8.0 clang revision 262564
Example program:
root@:~ # cat hello.c
#include <stdio.h>
int
main(int argc, char *argv[])
{
printf("Hello, world\n");
printf("Another line\n");
return 0;
}
root@:~ # cc -g hello.c
root@:~ #
Breakpoints work as expected:
root@:~ # lldb ./a.out
(lldb) target create "./a.out"
Current executable set to './a.out' (arm).
(lldb) b 6
Breakpoint 1: where = a.out`main + 36 at hello.c:6, address = 0x00008648
(lldb) run
Process 533 launching
Process 533 launched: '/root/a.out' (arm)
Process 533 stopped
* thread #1: tid = 100045, 0x00008648 a.out`main(argc=1, argv=0xbfbfed74) + 36
at hello.c:6, stop reason = breakpoint 1.1
frame #0: 0x00008648 a.out`main(argc=1, argv=0xbfbfed74) + 36 at hello.c:6
3 int
4 main(int argc, char *argv[])
5 {
-> 6 printf("Hello, world\n");
7 printf("Another line\n");
8 return 0;
9 }
But stepping does not; the program just continues.
(lldb) step
(lldb) Hello, world
Another line
Process 533 exited with status = 0 (0x00000000)
Instruction step (stepi) fails the same way.
