2014-12-30Remove "dll-symbols", "add-shared-symbol-files" and assf" commands.Joel Brobecker2-93/+9
This patch removes a set of commands that have been deprecated for a while, and which we agreed to remove after the GDB 7.8 release. gdb/ChangeLog: * windows-nat.c (safe_symbol_file_add_stub) (safe_symbol_file_add_cleanup, safe_symbol_file_add) (dll_symbol_command): Delete. (_initialize_windows_nat): Delete local variable "c". Remove "dll-symbols", "add-shared-symbol-files" and assf" commands. Tested by rebuilding GDB on x86-windows.

2014-12-29Sanitize input_interrupt outputSergio Durigan Junior2-3/+19
Hi, This patch is a follow-up of the following discussions: <https://sourceware.org/ml/gdb-patches/2014-12/msg00421.html> <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01293.html> input_interrupt is currently emiting non-printable characters, which is confusing the dg-extract-results.sh script. This is obviously not a good thing, and, by following Pedro's advices here: <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01320.html> I adapted the function to print "client connection closed" when it receives a NUL character, or use the "isprint" function to decide how to print the received char. I tested it by running the testcases that were printing the non-printable chars before: gdb.base/gdb-sigterm.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp and confirming that they print the right message. I tried a bit to come up with a testcase for this, but failed, and since I did not want to spend too much time on it, I'm sending the patch anyway. Comments are welcome, as usual. gdb/gdbserver/ChangeLog: 2014-12-29 Sergio Durigan Junior <sergiodj@redhat.com> * remote-utils.c: Include ctype.h. (input_interrupt): Explicitly handle the case when the char received is the NUL byte. Improve the printing of non-ASCII characters.

This patch is to clean up gdb.trace/entry-values.exp as a preparation of the next patch. It updates the comments to reflect the code. One DIE generated in dwarf assembler is GNU_call_site { {low_pc "$bar_start + $bar_call_foo" addr} {abstract_origin :$foo_label} the DW_AT_low_pc attribute is the return address after the call, so I rename variable bar_call_foo to returned_from_foo. gdb/testsuite: 2014-12-29 Yao Qi <yao@codesourcery.com> * gdb.trace/entry-values.exp: Update comments. Rename variable bar_call_foo to returned_from_foo.

2014-12-24AVR: Assembler now prepares for linker relaxation by default.Andrew Burgess12-18/+56
Have the assembler prepare for linker relaxation by default. This means that users will be able to make use of linker relaxation without having to adjust the assembler flags, this can make life easier when compiling libraries. Having this on by default in the assembler should make no difference to the assembler code produced, however, some of the debug information will be slightly less compressed. A few tests needed to be updated as a result of this change as they relied on linker relaxation support being off by default. I've tightened up the definition of which sections can be relaxed on AVR as part of this commit, the assembler used to think that all non-debugging sections could be relaxed, when in reality only code sections can be relaxed for AVR. The previous definition was not dangerous, just over cautious. The new tighter definition allows an extra test (gas/testsuite/gas/all/forward.d) to continue to pass. gas/ChangeLog: * config/tc-avr.c (struct avr_opt_s): Change link_relax to no_link_relax, extend comment.

2014-12-24Don't create .eh_frame_hdr on shared lib bfdAlan Modra2-1/+10
If no object files have .eh_frame, but some shared library does, then ld creates a .eh_frame_hdr section using the shared library bfd. This is silly since shared library .eh_frame sections don't contribute to the output .eh_frame and thus no .eh_frame_hdr is needed. Also, the bfd section list and count is cleared for shared libraries, and a zero section count used as a flag in lang_check to omit a call to bfd_merge_private_bfd_data for shared libraries. If we create a section on a shared lib bfd then ld will wrongly attempt to merge the shared library private bfd data.

2014-12-23AVR/ld: Propagate link-relax elf header flag correctly.Andrew Burgess13-0/+160
The AVR target has an elf header flag to indicate if an object was assembler ready for linker relaxation. If a partial link is performed then it is important that the link-relax flag in the output object is set correctly, otherwise, during the final link, we might try to perform linker relaxation on code that was not assembled suitably. As the link-relax elf header covers the entire object file we must be conservative when setting the flag in the output object, so, for a partial link, any input object that does not have the link-relax flag set will cause the output object to also not have the link-relax flag set. This conservative approach could be softened in future, we only need to disable the link relax flag if an input file is not marked link-relax ready, and the input file contains a relaxable section. However, I've left this optimisation for a later day. For the final link I've overloaded the use of the link-relax elf header flag, in a final executable, the flag now indicates if the executable was built with linker relaxation on or not. ld/ChangeLog: * emultempl/avrelf.em: Add include of elf/avr.h.

2014-12-23AVR: Only set link-relax elf flag when appropriate.Andrew Burgess9-2/+53
The AVR target uses a bit in the elf header flags to indicate if the object was assembled ready for linker relaxation.
