2015-07-24Initialise target descrption after skipping extra traps for --wrapperYao Qi8-13/+84
Nowadays, when --wrapper is used, GDBserver skips extra traps/stops in the wrapper program, and stops at the first instruction of the program to be debugged. However, GDBserver created target description in the first stop of inferior, and the executable of the inferior is the wrapper program rather than the program to be debugged. In this way, the target description can be wrong if the architectures of wrapper program and program to be debugged are different. This is shown by some fails in gdb.server/wrapper.exp on buildbot. We are testing i686-linux GDB (Fedora-i686) on an x86_64-linux box (fedora-x86-64-4) in buildbot, such configuration causes fails in gdb.server/wrapper.exp like this: spawn /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/../../gdb/gdbserver/gdbserver --once --wrapper env TEST=1 -- :2346 /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/outputs/gdb.server/wrapper/wrapper Process /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/outputs/gdb.server/wrapper/wrapper created; pid = 8795 Can't debug 64-bit process with 32-bit GDBserver Exiting target remote localhost:2346 localhost:2346: Connection timed out. (gdb) FAIL: gdb.server/wrapper.exp: setting breakpoint at marker See https://sourceware.org/ml/gdb-testers/2015-q3/msg01541.html In this case, program to be debugged ("wrapper") is 32-bit but wrapper program ("/usr/bin/env") is 64-bit, so GDBserver gets the 64-bit target description instead of 32-bit. The root cause of this problem is that GDBserver creates target description too early, and the rationale of fix could be creating target description once the GDBserver skips extra traps and inferior stops at the first instruction of the program we want to debug. IOW, when GDBserver skips extra traps, the inferior's tdesc is NULL, and mywait and its callees shouldn't use inferior's tdesc, so in this patch, we skip code that requires register access, see changes in linux_resume_one_lwp_throw and need_step_over_p. In linux_low_filter_event, if target description isn't initialised and GDBserver attached the process, we create target description immediately, because GDBserver don't have to skip extra traps for attach, IOW, it makes no sense to use --attach and --wrapper together. Otherwise, the process is launched by GDBserver, we keep the status pending, and return. After GDBserver skipped extra traps in start_inferior, we call a target_ops hook arch_setup to initialise target description there. gdb/gdbserver: 2015-07-24 Yao Qi <yao.qi@linaro.org> * linux-low.c (linux_arch_setup): New function.

2015-07-24Set proc->priv->new_inferior out of linux_add_processYao Qi2-5/+15
Nowadays, we set proc->priv->new_inferior to 1 inside linux_add_process, and new_inferior is used as a flag to initialise target description later. linux_add_process is used for the three cases, fork/vfork event (handle_extended_wait), run the program (linux_create_inferior), and attach to the process (linux_attach). In the first case, the child's target description is copied from parent's, so we don't need to initialise target description again later, which means we don't need to set proc->priv->new_inferior to 1 in this case. For the rest of two cases, we need this flag. This patch move the code setting proc->priv->new_inferior to 1 inside linux_add_process to linux_create_inferior and linux_attach. No functionality is changed. gdb/gdbserver: 2015-07-24 Yao Qi <yao.qi@linaro.org> * linux-low.c (linux_add_process): Don't set proc->priv->new_inferior. (linux_create_inferior): Set proc->priv->new_inferior to 1. (linux_attach): Likewise.

2015-07-24Test --wrapper when restarting process.Yao Qi2-0/+25
My patch series will affect the code starting inferior in GDBserver (callees of start_inferior), so we need tests to cover how start_inferior is used in different cases. In server.c:process_serial_event, start_inferior is used when GBDserver receives 'R' packet, and this patch is to add a test for this path, and see how --wrapper option works when the process is restarted. gdb/testsuite: 2015-07-24 Yao Qi <yao.qi@linaro.org> * gdb.server/ext-wrapper.exp: Test --wrapper option when restarting process.

2015-07-23Fix DT_MIPS_RLD_MAP_REL tag for n64 target and 32-bit host.Joseph Myers2-1/+7
For the case of MIPS n64 target and 32-bit host, the computation of the DT_MIPS_RLD_MAP_REL tag involves sdyn->output_section->vma + sdyn->output_offset (64-bit) being added to b (32-bit host pointer), so losing the high part and resulting in an incorrect DT_MIPS_RLD_MAP_REL tag, and all dynamically linked glibc tests failing for n64. This patch fixes this (spot-tested with glibc tests; however, I don't have a self-contained testcase for this bug). * elfxx-mips.c (_bfd_mips_elf_finish_dynamic_sections) <DT_MIPS_RLD_MAP_REL>: Add target address to host address difference, not to host pointer.

2015-07-23gdb/gdbtypes: fix handling of typedef layers between array typesPierre-Marie de Rodat7-1/+140
When a dynamic array type contains a typedef-wrapped array, an assertion failure occurs during type resolution. This is what happens in the following Ada case: type Rec_Type is record I : Integer; B : Boolean; end record; type Vec_Type is array (1 .. 4) of Rec_Type; type Array_Type is array (Positive range <>) of Vec_Type; If users try to print or even pass to an inferior call a variable A of type Array_Type, GDB will raise an error: (gdb) print a ../../src/gdb/gdbtypes.c:1807: internal-error: resolve_dynamic_array: Assertion `TYPE_CODE (type) == TYPE_CODE_ARRAY' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) What happens is that during dynamic array type resolution, we first peel TYPE_CODE_TYPEDEF layers wrapping the array element type and check if its type is itself TYPE_CODE_ARRAY. If it is, we pass the typedef-wrapped type to a recursive call to resolve_dynamic_array whereas this function expects only TYPE_CODE_ARRAY types. This patch makes it pass the peeled type to the recursive call so that type resolution can continue smoothly. gdb/ChangeLog: * gdbtypes.c (resolve_dynamic_array): Pass the peeled element type to the recursive call instead of the original (maybe TYPE_CODE_TYPEDEF) type. gdb/testsuite/ChangeLog: * gdb.ada/var_arr_typedef.exp: New testcase. * gdb.ada/var_arr_typedef/pack.adb: New file. * gdb.ada/var_arr_typedef/pack.ads: New file. * gdb.ada/var_arr_typedef/var_arr_typedef.adb: New file.

HW watchpoint/breakpoint Nowadays aarch64_linux_can_use_hw_breakpoint always return one, but it can be smarter, say, if GDB knows target doesn't support HW watchpoint or breakpoint because HW watchpoint/breakpoint is disabled in linux kernel, for example, it can safely return zero. gdb: 2015-07-23 Yao Qi <yao.qi@linaro.org> * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): If TYPE is watchpoint, return zero if aarch64_num_wp_regs is zero.

2015-07-20Make binutils abort message GDB friendlyH.J. Lu3-8/+8
We used to generate abort messages like: internal error, aborting at .../bfd/elf64-x86-64.c line 1554 in elf_x86_64_check_relocs We can't cut and paste "file line ???" to GDB. This patch changes those abort messages to internal error, aborting at .../bfd/elf64-x86-64.c:1554 in elf_x86_64_check_relocs so that we can cut and paste "file:???" to GDB. bfd/ * bfd.c (_bfd_abort): Replace " line " with ":" in output message. gas/ * messages.c (as_assert): Replace " line " with ":" in output message. (as_abort): Likewise. ld/ * ldmisc.c (ld_abort): Replace " line " with ":" in output message.

2015-07-20ALIGN change affects cris scriptsAlan Modra3-4/+12
More fallout from a2c59f28. This one could have been fixed by simply using ". = ALIGN (ABSOLUTE (.), 2);" but it's nicer to align the section. * emulparams/criself.sh (INIT_ADDR, FINI_ADDR): Define. (INIT_START, FINI_START): Don't ALIGN. * scriptempl/elf.sc (.init, .fini): Apply INIT_ADDR/FINI_ADDR.
2015-07-20ALIGN change affects standard scriptsAlan Modra3-26/+48
a2c59f28 changed the way the unary ALIGN behaved inside output sections, resulting in cris-elf testsuite regressions. This patch pads out .bss in the same manner as it was prior to the ALIGN change. * scripttempl/elf.sc (.ldata, .bss): Align absolute value of dot. * ldexp.c (is_align_conditional): Handle binary ALIGN. (exp_fold_tree_1): Move code setting SEC_KEEP for assignments to dot inside output sections. Handle absolute expressions.
