The tests gdb.reverse/solib-precsave.exp and solib-reverse.exp have the assumption that line tables will have an entry for the closing } in a function. Not all compiles do this, one example being clang. To fix this, this commit changes the function in shr2.c to have multiple lines, and the test to accept either line as a correct step location. To properly re-sync the inferiors, the function repeat_cmd_until had to be slightly changed to work with empty "current locations", so that we are able to step through multiple lines. This also changes the annotations used to determine the breakpoint locations in solib-reverse.c, adding a simple variable assignment right before the return statement. This way GDB will not set a breakpoint in the closing } line. Approved-By: Tom Tromey <tom@tromey.com>
