2014-08-06Rename variable with confusing nameSimon Marchi2-17/+22
I saw this gem of not so legible code in solib-svr4.c (scan_dyntag): if (dyn_tag == dyntag) and thought it deserved a small rename. This just renames variables to be a bit more clear for those who read the code. I also constified the parameter because, why not. The same was done in scan_dyntag_auxv as well. Tested only by rebuilding, since the change was done mechanically. gdb/Changelog: 2014-08-01 Simon Marchi <simon.marchi@ericsson.com> * solib-svr4.c (scan_dyntag): Rename dyntag and dyn_tag variables.

2014-08-05Fix LTO vs. COFF archivesAlan Modra10-560/+187
Avoid scan of symbols on objects in coff archives since we don't need to do anything special with common symbols. The scan is quite useless, and breaks LTO due to slim LTO objects not having symbols available until after the plugin has claimed them. Instead we can add objects based on their archive symbol map. Also, rip out the archive symbol hash table used by the generic linker. Using a hash breaks one feature of unix archive linking; The first object file in an archive defining any given symbol should be the object extracted to satisfy that symbol. What's more a hash isn't much faster except in pathological cases where object file ordering causes many scans of the archive. See the comment which I'm removing from elf_link_add_archive_symbols. Finally, tidy elflink.c archive handling a little.

2014-08-04make "set debug target" take effect immediatelyTom Tromey6-6/+29
Right now, "set debug target" acts a bit strangely. Most target APIs only notice that it has changed when the target stack is changed in some way. This is because many methods implement the setting using the special debug target. However, a few spots do change their behavior immediately -- any place explicitly checking "targetdebug". Some of this peculiar behavior is documented. However, I think that it just isn't very useful for it to work this way. So, this patch changes "set debug target" to take effect immediately in all cases. This is done by simply calling update_current_target when the setting is changed. This required one small change in the test suite. Here a test was expecting the current behavior. Built and regtested on x86-64 Fedora 20. 2014-08-04 Tom Tromey <tromey@redhat.com> * target.c (set_targetdebug): New function. (initialize_targets): Pass set_targetdebug when creating "set debug target". 2014-08-04 Tom Tromey <tromey@redhat.com> * gdb.texinfo (Debugging Output): Update for change to "set debug target". 2014-08-04 Tom Tromey <tromey@redhat.com> * gdb.base/sss-bp-on-user-bp-2.exp: Expect output from "set debug target 0".

2014-08-01Handle variable-sized fields in the interior of structure typeJoel Brobecker5-26/+50
In Ada, variable-sized field can be located at any position of a structure. Consider for instance the following declarations: Dyn_Size : Integer := 1; type Table is array (Positive range <>) of Integer; type Inner is record T1 : Table (1 .. Dyn_Size) := (others => 1); T2 : Table (1 .. Dyn_Size) := (others => 2); end record; type Inner_Array is array (1 .. 2) of Inner; type Outer is record I0 : Integer := 0; A1 : Inner_Array; Marker : Integer := 16#01020304#; end record; Rt : Outer; What this does is declare a variable "Rt" of type Outer, which contains 3 fields where the second (A1) is of type Inner_Array. type Inner_Array is an array with 2 elements of type Inner. Because type Inner contains two arrays whose upper bound depend on a variable, the size of the array, and therefore the size of type Inner is dynamic, thus making field A1 a dynamically-size field. When trying to print the value of Rt, we hit the following limitation: (gdb) print rt Attempt to resolve a variably-sized type which appears in the interior of a structure type The limitation was somewhat making sense in C, but needs to be lifted for Ada. This patch mostly lifts that limitation. As a result of this patch, the type length computation had to be reworked a little bit. gdb/ChangeLog: * gdbtypes.c (resolve_dynamic_struct): Do not generate an error if detecting a variable-sized field that is not the last field. Fix struct type length computation. gdb/testsuite/ChangeLog: * gdb.base/vla-datatypes.c (vla_factory): Add new variable inner_vla_struct_object_size. * gdb.base/vla-datatypes.exp: Adjust last test, and mark it as xfail.
2014-08-01Add debug trace in amd64-windows-tdep.c::amd64_windows_frame_decode_insnsJoel Brobecker2-0/+14
This is a trace which would have been useful when trying to understand why the debugger was not decoding the stream of unwind codes I was expecting. This patch adds a trace first informing us that we are following the unwind info to the next unwind record in that chain. gdb/ChangeLog: * amd64-windows-tdep.c (amd64_windows_frame_decode_insns): Add debug trace.
2014-08-01x64-windows: Fix extraction of chained UNWIND_INFOJoel Brobecker2-1/+6
On x86_64-windows, GDB is unable to unwind past some code in mswsock.dll. For instance: (gdb) bt #0 0x00000000778712fa in ntdll!ZwWaitForSingleObject () from C:\Windows\SYSTEM32\ntdll.dll #1 0x000007fefcfb0f75 in WSPStartup () from C:\Windows\system32\mswsock.dll Backtrace stopped: previous frame inner to this frame (corrupt stack?) The UNWIND_INFO record for frame #1's PC has a UNW_FLAG_CHAININFO flag, and so after having decoded this unwind record, GDB's decoder next tries to locate the next unwind record on the chain. Unfortunately, the location of that unwind info appears to be miscomputed. This is the expression used: chain_vma = cache->image_base + unwind_info + sizeof (ex_ui) + ((codes_count + 1) & ~1) * 2 + 8; The chain-info is expected to be right after the "Unwind codes array" which is itself after all the fields of ex_ui's struct. So the "+ 8" offset at the end should not be there. Because of that extra offset, we were reading no longer processing correct unwind info, leading the unwinder computing the wrong frame size, computing the wrong return address, etc. gdb/ChangeLog: * amd64-windows-tdep.c (amd64_windows_frame_decode_insns): Remove "+ 8" offset in computation of CHAIN_VMA.

2014-07-30fix to_open debug settingTom Tromey2-13/+32
This is a follow-on to the patch to auto-generate target debug methods. While working on that patch I noticed that the to_open debug setting will never work. There is no path by which debug_to_open can be called. This patch fixes the problem by using a generic function as the implementation of the various "target" subcommands, and then putting the debug printing there. This is also a tiny step toward fixing PR 7250 (and apparently why command contexts were introduced). Built and regtested on x86-64 Fedora 20. 2014-07-30 Tom Tromey <tromey@redhat.com> * target.c (open_target): New function.
