            Bug ID: 25913
           Summary: Command to step through line
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: cli
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

With gdb, we can step to the next line (step command) or next instruction
(stepi).

Consider the example from PR25911. We can step past line 6 with step, or step
through the instructions with stepi:
...
$ gdb a.out
Reading symbols from a.out...
(gdb) start
Temporary breakpoint 1 at 0x400496: file stmts-on-line.c, line 4.
Starting program: /data/gdb_versions/devel/a.out 

Temporary breakpoint 1, main () at stmts-on-line.c:4
4         int a = 4;
(gdb) s
6         a = 5; a = 6; a = 7;
(gdb) si
6         a = 5; a = 6; a = 7;
(gdb) si
6         a = 5; a = 6; a = 7;
(gdb) si
8         return 0;
...
but with gcc-10, there's an intermediate level between line and instruction:
the "recommended breakpoint location".

So, propose to add a command, say stepc for "step column" to step through the
"recommended breakpoint locations", which can be on the same line but several
instructions apart.
