I see the fail on aarch64-linux, (gdb) reverse-next Breakpoint 2, callee () at /home/yao/SourceCode/gnu/gdb/git/gdb/testsuite/gdb.reverse/step-reverse.c:26^M 26 myglob++; return 0; /* ARRIVED IN CALLEE */ (gdb) FAIL: gdb.reverse/next-reverse-bkpt-over-sr.exp: reverse-next over call trips user breakpoint at function entry The test expects program stops at line 25, but program stops at line 26.

I am not sure the line-table is correct, but it is not the point of this test. The goal of this test is to test program hits the breakpoint on the first instruction of function after 'reverse-next', so I change this test to expect the breakpoint number the program hits. gdb/testsuite: 2016-04-07 Yao Qi <yao.qi@linaro.org> * gdb.reverse/next-reverse-bkpt-over-sr.exp: Match the breakpoint number instead of the comments on some line.

|
|
# to get at the callee's caller. Test that a user breakpoint set at
