2016-06-21[Ada catchpoints] Fix "warning: failed to get exception name: No definition ↵Pedro Alves4-10/+50
of \"e.full_name\" in current context" Looking at testsuite results, I noticed this warning in an MI test: ~"\nCatchpoint " ~"2, " &"warning: failed to get exception name: No definition of \"e.full_name\" in current context.\n" ~"exception at 0x000000000040192d in foo () at /home/pedro/brno/pedro/gdb/mygit/src/gdb/testsuite/gdb.ada/mi_catch_ex/foo.adb:20\n" ~"20\t raise Constraint_Error; -- SPOT1\n" *stopped,reason="breakpoint-hit",disp="keep",bkptno="2",exception-name="CONSTRAINT_ERROR",frame={addr="0x000000000040192d",func="foo",args=[],file="/home/pedro/brno/pedro/gdb/mygit/src/gdb/testsuite/gdb.ada/mi_catch_ex/foo.adb",fullname="/home/pedro/brno/pedro/gdb/mygit/src/gdb/testsuite/gdb.ada/mi_catch_ex/foo.adb",line="20"},thread-id="1",stopped-threads="all",core="5" (gdb) PASS: gdb.ada/mi_catch_ex.exp: continue until CE caught by all-exceptions catchpoint The problem is that: - MI prints the breakpoint hit twice: once on the MI stream; another time on the console stream. - After printing the Ada catchpoint hit, gdb selects a non-current frame, from within the catchpoint's print_it routine. So the second time the breakpoint is printed, the selected frame is no longer the current frame, and then evaluating e.full_name in ada_exception_name_addr fails. This commit fixes the problem and enhances the gdb.ada/mi_catch_ex.exp test to make sure the catchpoint hit is printed correctly on the console stream too. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_exception_name_addr_1): Add comment.

2016-06-21Prepare gdb.python/mi-py-events.exp for Python/MI in separate channelsPedro Alves3-13/+33
Similarly to 5068630ad34dce5fefbe68d70d3a50cd8b92f71e (gdb.python/py-events.exp and normal_stop observers ordering) [1], this commit makes the gdb.python/py-mi-events.exp test not rely on order in which MI and Python observers run, or even on where each observer sends its output to. This shows up as a problem when testing with MI running as a separate terminal, for example, where Python event output and MI output go to different channels, even. But in any case, relying on the order in which observers run is always going to be fragile. The fix is to save the string output in the handlers in some variables and then having MI print them explicitly, instead of printing them directly from the Python events. Tested on x86_64 Fedora 23. https://sourceware.org/ml/gdb-patches/2015-07/msg00290.html gdb/testsuite/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * gdb.python/py-mi-events-gdb.py (stop_handler_str) (cont_handler_str): New.

2016-06-18Don't generate PLT for IFUNC GOT/pointer referenceH.J. Lu89-342/+1876
If a backend supports it, PLT entry isn't needed when all references to a STT_GNU_IFUNC symbols are done via GOT or static function pointers. For GOT entries, We generate dynamic R_*_GLOB_DAT relocations for preemptable symbols and R_*_IRELATIVE relocations for non-preemptable symbols to update them with real function address. For static pointer pointers, we generate dynamic pointer relocations and store them in: 1. .rel[a].ifunc section in PIC object. 2. .rel[a].got section in dynamic executable. 3. .rel[a].iplt section in static executable.

2016-06-17Handle reinsert breakpoints for vforked childYao Qi4-5/+91
When a thread is doing step-over with reinsert breakpoint, and the instruction executed is a syscall doing vfork, both parent and child share the memory, so the reinsert breakpoint in the space is visible to both of them. Also, removing the reinsert breakpoints from the child will effectively remove them from the parent. We should carefully manipulate reinsert breakpoints for both processes. What we are doing here is that - uninsert reinsert breakpoints from the parent before cloning the breakpoint list. We use "uninsert" instead of "remove", because we need to "reinsert" them back after vfork is done. In fact, "uninsert" removes them from both child and parent process space. - reinsert breakpoints in parent process are still copied to child's breakpoint list, - remove them from child's breakpoint list as what we did for fork, at this point, reinsert breakpoints are removed from the child and the parent, but they are still tracked by the parent's breakpoint list, - once vfork is done, "reinsert" them back to the parent, gdb/gdbserver: 2016-06-17 Yao Qi <yao.qi@linaro.org> * linux-low.c (handle_extended_wait): Call uninsert_reinsert_breakpoints for the parent process.

If the syscall call is fork, the forked child has reinsert breakpoint in its space, and GDBserver clones parent's breakpoint list to child's. When GDBserver resumes the child, its bp_reinsert is zero, but has reinsert breakpoints, so the following assert is triggered if I apply the patch extending step-over-syscall.exp. gdb/gdbserver/linux-low.c:4292: A problem internal to GDBserver has been detected.^M void linux_resume_one_lwp_throw(lwp_info*, int, int, siginfo_t*): Assertion `!has_reinsert_breakpoints (proc)' failed. gdb/gdbserver: 2016-06-17 Yao Qi <yao.qi@linaro.org> * linux-low.c (handle_extended_wait): If the parent is doing step-over, remove the reinsert breakpoints from the forked child.
2016-06-17Step over exit with reinsert breakpointsYao Qi5-0/+196
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. See gdbserver logs below, Need step over [LWP 14858]? yes, found breakpoint at 0x2aaaaad91307^M proceed_all_lwps: found thread 14858 needing a step-over^M Starting step-over on LWP 14858.

This allows the assembler to properly realize when a new instruction needs a higher architecture (after v9b) and to react accordingly emitting an error message or bumping the architecture.

2016-06-17gas: sparc: fix collision of registers and pseudo-ops.Jose E. Marchesi2-141/+264
The current sparc assembler breaks when the name of an ancillary-state register, privileged register or hyperprivileged register has a %-pseudo-operation name as a prefix. For example, %hmcdper and %hm(), or %hintp and %hi(). This patch fixes it by introducing a new table `perc_table' (for %-table) that contains an entry for every %name supported by the assembler, other than the general registers. This table is used to detect name collisions when the assembler tries to detect a %-pseudo-op. This patch also fixes a related bug, making sure that v9a_asr_table and hpriv_reg_table are sorted in reverse lexicographic order, as otherwise the search code may fail. gas/ChangeLog: 2016-06-17 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c (priv_reg_table): Use NULL instead of the empty string to mark the end of the array. (hpriv_reg_table): Likewise. (v9a_asr_table): Likewise.

Note that for arches up to v9b (UltraSPARC III), the detection of the BFD machine type was based on the bits in the e_machine field of the ELF header. However, there are no more available bits in that field, so this patch takes the approach of using the hardware capabilities stored in the object attributes HWCAPS/HWCAPS2 in order to characterize the machine the object was built for. bfd/ChangeLog: 2016-06-17 Jose E.

Type lengths are unsigned, so they are always greater than or equal to zero. A check against the length of 'tgt_type' is retained to prevent dividing by zero. gdb/ChangeLog: * v850-tdep.c (v850_use_struct_convention): Trim type length checks.
2016-06-14Pass a NULL pointer as the last argument to find_pc_partial_function.John Baldwin2-1/+5
gdb/ChangeLog: * tui/tui-stack.c (tui_show_frame_info): Fix type mismatch.
2016-06-14Initialize 'ra' to zero to avoid uninitialized use.John Baldwin2-0/+5
If the instruction in this case does not include an RA field, then 'ra' is used uninitialized. Use the same idiom used elsewhere in this file of initializing ra to zero before check for an RA field. gdb/ChangeLog: * rs6000-tdep.c (ppc_process_record_op31): Initialize ra.
2016-06-14Change the size field of MSP430_Opcode_Decoded to a plain integer.John Baldwin2-8/+6
The size field was defined as an instance of an enum, but existing code treats the size field as a plain integer containing a bit count. include/ChangeLog: * opcode/msp430-decode.h (MSP430_Size): Remove. (Msp430_Opcode_Decoded): Change type of size to int.
2016-06-14Use correct enum type for do_elf_stt_common.John Baldwin2-1/+5
binutils/ChangeLog: * objcopy.c (do_elf_stt_common): Use correct type.
2016-06-14Check R_*_IRELATIVE in x86 reloc_type_classH.J. Lu3-11/+23
elf_{i386|x86_64}_reloc_type_class should return reloc_class_ifunc for R_386_IRELATIVE/R_X86_64_IRELATIVE relocations. There is no need to check symbol type for STN_UNDEF symbol index. * elf32-i386.c (elf_i386_reloc_type_class): Check R_386_IRELATIVE. Don't check symbol type for STN_UNDEF symbol index. * elf64-x86-64.c (elf_x86_64_reloc_type_class): Check R_X86_64_IRELATIVE. Don't check symbol type for STN_UNDEF symbol index.
2016-06-14Fix elf_x86_64_reloc_type_classH.J. Lu1-8/+14
