2016-07-01Extend JIT-reader test and fix GDB problems that exposesPedro Alves3-12/+241
The jit-reader.exp test isn't really exercising the jit-reader's unwinder API at all. This commit address that, and then fixes GDB problems exposed. - The custom JIT reader provided for the jit-reader.exp testcase always rejects the jitted function's frame... This is because the custom JIT reader in the testcase never ever sets state->code_begin/end, so the bounds check in gdb.base/jitreader.c:unwind_frame: if (this_ip >= state->code_end || this_ip < state->code_begin) return GDB_FAIL; tends to fail, unless you're "lucky" (because it references uninitialized data). The result is that GDB is always actually using a built-in unwinder for the jitted function. - The provided unwinder doesn't do anything that GDB's built-in unwinder can't do. IOW, we can't really tell whether the JIT reader's unwinder is working or not. I fixed that by making the jitted function mangle its own stack pointer with a xor, and then teaching the jit unwinder to demangle it back (another xor). So now "backtrace" with GDB's built-in unwinder fails while with the jit unwinder, it succeeds. - GDB crashes after unloading the JIT reader, and flushing frames... I made the testcase use the "flushregs" command after unloading the JIT reader, to force the JIT frames to be flushed. However, that crashes GDB... When reinit_frame_cache tears down a frame's cache, it calls its unwinder's dealloc_cache method, which for JIT frames ends up in jit.c:jit_dealloc_cache. This function calls each of the frame's gdb_reg_value's "free" pointer: for (i = 0; i < gdbarch_num_regs (frame_arch); i++) if (priv_data->registers[i] && priv_data->registers[i]->free) priv_data->registers[i]->free (priv_data->registers[i]); and the problem is these gdb_reg_value instances have been returned by the JIT reader that has been already unloaded, and their "free" function pointers likely point to functions in the DSO that has already been unloaded... A fix for that could be to call reinit_frame_cache in jit_reader_unload_command _before_ unloading the jit reader DSO so that the jit reader is given a chance to clean up the gdb_reg_values before it is unloaded. However, the fix for the point below makes this unnecessary, because it stops jit.c from keeping around gdb_reg_values in the first place. - However, it still makes sense to clear the frame cache when loading or unloading a JIT unwinder. This makes testing a JIT unwinder a bit simpler. - Not only the frame cache actually -- gdb is not unloading the jit-registered objfiles when the JIT reader is unloaded, and not loading the already-registered descriptors when a JIT reader is loaded. The new test exercises unloading the jit reader, loading it back again, and then making sure the JIT reader's unwinder works again. Without the unload/re-load of already-read descriptors, the newly loaded JIT would have no idea where the new function is, because it's stored at symbol read time. - I added a couple "info frame" calls to the test, and that crashes GDB... The problem is that jit_frame_prev_register assumes it'll only be called for raw registers, so when it gets a pseudo register number, the "priv->registers[reg]" access is really an out-of-bounds access. To fix that, I made jit_frame_prev_register use gdbarch_pseudo_register_read_value for reading the pseudo-registers. However, that works with a regcache and we don't have one. To fix that, I made the JIT unwinder store a regcache in its cache instead of an array of gdb_reg_value pointers. gdb/ChangeLog: 2016-07-01 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * jit.c (jit_reader_load_command): Call reinit_frame_cache and jit_inferior_created_hook.

2016-06-29Set unknown_syscall differently on arm linuxYao Qi1-0/+8
Currently, we use 123456789 as unknown or illegal syscall number, and expect program return ENOSYS. Although 123456789 is an illegal syscall number on arm linux, kernel sends SIGILL rather than returns -ENOSYS. However, arm linux kernel returns -ENOSYS if syscall number is within 0xf0001..0xf07ff, so we can use 0xf07ff for unknown_syscall in test. gdb/testsuite: 2016-06-29 Yao Qi <yao.qi@linaro.org> * gdb.base/catch-syscall.c [__arm__]: Set unknown_syscall to 0x0f07ff.
2016-06-28Probe catch syscall supportYao Qi1-14/+29
In 82075af2c14b1f8a54fa5796fb63f7ef23f98d9d (Implement 'catch syscall' for gdbserver), only x86 is supported, but the test can still be run on other linux targets, like aarch64 and ppc, with native-gdbserver. This causes many new fails. This patch removes the check on isnative and on target triplets. Instead, we can insert catch point, and resume the program to see whether catch syscall is supported or not. gdb/testsuite: 2016-06-28 Yao Qi <yao.qi@linaro.org> * gdb.base/catch-syscall.exp: Remove check on isnative and target triplets.

2016-06-17Step over exit with reinsert breakpointsYao Qi2-0/+177
This patch fixes a GDBserver crash when one thread is stepping over a syscall instruction which is exit. Step-over isn't finished due to the exit, but GDBserver doesn't clean up the state of step-over, so in the wait next time, GDBserver will wait on step_over_bkpt, which is already exited, and GDBserver crashes because 'requested_child' is NULL.

2016-06-13gdb: Use UNSUPPORTED not XFAIL for unsupported target featuresAndrew Burgess12-29/+13
If a target does not support making function calls from GDB then in a number of test files, we currently report an XFAIL and skip some, or all of the tests. This commit changes the XFAIL to an UNSUPPORTED as this seems more appropriate in these cases. Some of the tests used bug ID 2416 to be reported in the XFAIL.

2016-05-27gdb: Forward VALUE_LVAL when avoiding side effects for STRUCTOP_PTRAndrew Burgess2-4/+87
Assume that we have a C program like this: struct foo_type { int var; } foo; struct foo_type *foo_ptr = &foo; int main () { return foo_ptr->var; } Then GDB should be able to evaluate the following, however, it currently does not: (gdb) start ... (gdb) whatis &(foo_ptr->var) Attempt to take address of value not located in memory. The problem is that in EVAL_AVOID_SIDE_EFFECTS mode, eval.c:evaluate_subexp_standard always returns a not_lval value as the result for a STRUCTOP_PTR operation. As a consequence, the rest of the code believes that one cannot take the address of the returned value. This patch fixes STRUCTOP_PTR handling so that the VALUE_LVAL attribute for the returned value is properly initialized. After this change, the above session becomes: (gdb) start ... (gdb) whatis &(foo_ptr->var) type = int * This commit is largely the same as commit 2520f728b710 (Forward VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT) but applied to STRUCTOP_PTR rather than STRUCTOP_STRUCT. Both of these commits are building on top of commit ac1ca910d74d (Fixes for PR exp/15364). gdb/ChangeLog: * eval.c (evaluate_subexp_standard): If EVAL_AVOID_SIDE_EFFECTS mode, forward the VALUE_LVAL attribute to the returned value in the STRUCTOP_PTR case. gdb/testsuite/ChangeLog: * gdb.base/whatis.c: Extend the test case. * gdb.base/whatis.exp: Add additional tests.

2016-05-16Match shell_prompt # in batch-preserve-term-settings.expYao Qi1-2/+1
batch-preserve-term-settings.exp fails if the shell prompt isn't $. It is # in our testing env. In fact, the shell prompt can be anything. The perfect solution would be "set_board_info shell_prompt" in the host board file, and use board_info shell_prompt in batch-preserve-term-settings.exp. This is a little bit overkill to me, and we still need to figure out the different prompts on different shells. I also tried to start shell with the prompt preset, but there is not unique way to set shell prompt in different shells, so I give up. It is reasonably simple to match either $ or # for the shell prompt, and we can easily extend it to match other char, like >. gdb/testsuite: 2016-05-16 Yao Qi <yao.qi@linaro.org> * gdb.base/batch-preserve-term-settings.exp: Remove variable shell_prompt.

2016-05-04Fix solib-display.exp remote checkSimon Marchi1-1/+18
This test currently uses [is_remote target] to check if the test is supported. This is not quite correct, as the limitation is actually that it requires support for "running", ruling out stub-like targets. Therefore, it should check for use_gdb_stub. This has no visible effect right now, but it will once we make the native-gdbserver board non-dejagnu-remote. gdb/testsuite/ChangeLog: * gdb.base/solib-display.exp: Check for [use_gdb_stub] instead of [is_remote target],
2016-05-02Fix detach.exp remote checkSimon Marchi1-5/+0
This test seems to work with both native-gdbserver and native-extended-gdbserver, so I removed the remote check. When running with native-gdbserver (a stub-like target), detach makes gdbserver stop and gdb disconnect. runto_main just spawns a brand new gdbserver. So it tests the exact same thing twice. It doesn't hurt though. With native-extended-gdbserver, the test is probably a bit more useful (and similar to native). It tests running/detaching twice using the same gdb/gdbserver instances, since with extended-remote, you can detach/attach/run all you want, unlike with remote. gdb/testsuite/ChangeLog: * gdb.base/detach.exp: Remove is_remote check.
2016-05-02Fix annota-input-while-running.exp remote checkSimon Marchi1-19/+6
The comment says that we can't use runto_main here becore it doesn't know how to handle annotation. Instead, the test puts a breakpoint at main and calls run by hand. Therefore, it can't work with stub targets, since they can't "run". The check should be then changed to check the use_gdb_stub variable instead of [is_remote target]. But as an alternative, we can just use runto_main and enable annotations after, since the "run to main" part is not really part of what we want to test. I also removed the "set test..." line that is unused. gdb/testsuite/ChangeLog: * gdb.base/annota-input-while-running.exp: Don't check for [is_remote target]. Enable annotations after running to main. Remove unused "set test..." line.

2016-04-27Make gdb_load_shlibs return the destination path of the librarySimon Marchi9-9/+18
This patch makes gdb_load_shlibs return the destination path of the copied library. To make the procedure implementation and interface more straightforward, it also changes it so that it accepts a single shared library path at the time. Therefore, calls that are passed multiple libraries: gdb_load_shlibs $lib1 $lib2 must be changed to separate calls: gdb_load_shlibs $lib1 gdb_load_shlibs $lib2 A subtle impact is the solib-search-path handling. In the former version, solib-search-path is set using the directory of the first passed lib (further calls overwrite the value). In the later version, the directory of the library passed to the last call to gdb_load_shlibs remnains. I don't think that's a problem in practice, since if we had tests that needed multiple different paths in solib-search-path, they wouldn't work in the first place.

Hi, I am seeing the fail below on aarch64-linux with gcc 4.9.2, break main Breakpoint 1 at 0x4006e8: file binutils-gdb/gdb/testsuite/gdb.base/annota1.c, line 14.^M (gdb) FAIL: gdb.base/annota1.exp: breakpoint main the test expects the breakpoint is set on line 15.

Program hits breakpoint on either line 14 or line 15 is right to me. With anther gcc (4.9.3), the line-table looks correct, and no test fail. Instead of setting breakpoint on main and assuming the line is what we get from the source, we can set breakpoint on that line. On the other hand, the test prints the values of the array and check, so we need to set breakpoint on the line setting the values of array and "next", rather than setting the breakpoint on main. gdb/testsuite: 2016-04-22 Yao Qi <yao.qi@linaro.org> * gdb.base/annota1.exp: Set breakpoint on line $main_line. * gdb.base/annota3.exp: Likewise.

2016-04-05Improve gdb_remote_download, remove gdb_downloadSimon Marchi2-10/+2
This patch removes gdb_download in favor of gdb_remote_download, since they are very close in functionality. Also, in preparation for the following patch about shared library handling during tests, it improves gdb_remote_download so that it uses standard_output_file for any destination board that is local, not only host. If the destination board is remote, gdb_remote_download will use the standard remote_download from DejaGnu, resulting in the file being transferred on the remote system. If the destination is local, gdb_remote_download will copy the file to the standard test directory (found using standard_output_file). Tcl's file copy seems to handle gracefully cases where the source file is the same as the destination, so I don't think it's necessary to check for that case ourselves, as a previous version of the patch did. I'd prefer to keep the name gdb_download instead of gdb_remote_download, since I don't like the fact that gdb_remote_download implies that the destination is remote, when it's not always the case. However, gdb_remote_download is used at many more places than gdb_download, so it's easier to reuse that. Also, since it's a wrapper around DejaGnu's remote_download, it might be better to keep that name. I don't know. I ran the testsuite native, with native-gdbserver and with a remote gdbserver, and didn't see any related failure. gdb/testsuite/ChangeLog: * gdb.base/jit-so.exp: Use gdb_remote_download instead of gdb_download.
