Luis Machado	6ae8866180	Fix problems with finishing a dummy function call on simulators. Some simulators don't handle permanent breakpoints properly and will sometimes terminate when hitting such a breakpoint instruction or have unwanted effects. When a permanent breakpoint is inserted, GDB will not attempt to insert other breakpoint locations on top of it, leading to the problem described above. By not marking permanent breakpoint locations as inserted, we allow the insertion of breakpoint locations on top of the permanent ones, preventing the simulators from running into that situation. gdb/ChangeLog: 2015-06-17 Luis Machado <lgustavo@codesourcery.com> * breakpoint.c (add_location_to_breakpoint): Don't mark permanent locations as inserted. Update and expand comment about permanent locations. (bp_loc_is_permanent): Don't return 0 for bp_call_dummy. Move comment to add_location_to_breakpoint.

Patrick Palka	bc460514b9	Tweak the handling of $GDBHISTSIZE edge cases [PR gdb/16999] When GDB reads a nonsensical value for the GDBHISTSIZE environment variable, i.e. one that is non-numeric or negative, GDB then sets its history size to 0. This behavior is annoying and also inconsistent with the behavior of bash. This patch makes the behavior of invalid GDBHISTSIZE consistent with how bash handles HISTSIZE. When we encounter a null or out-of-range GDBHISTSIZE (outside of [0, INT_MAX]) we now set the history size to unlimited instead of 0. When we encounter a non-numeric GDBHISTSIZE we do nothing. gdb/ChangeLog: PR gdb/16999 * NEWS: Mention new GDBHISTSIZE behavior. * top.c (init_history): For null or out-of-range GDBHISTSIZE, set history size to unlimited. Ignore non-numeric GDBHISTSIZE. gdb/doc/ChangeLog: PR gdb/16999 * gdb.texinfo (Command History): Mention new GDBHISTSIZE behavior. gdb/testsuite/ChangeLog: PR gdb/16999 * gdb.base/gdbhistsize-history.exp: New test.	11 years ago
Patrick Palka	b58c513b79	Read $GDBHISTSIZE instead of $HISTSIZE The HISTSIZE environment variable is generally expected to be read by shells, not by applications. Some distros for example globally export HISTSIZE in /etc/profile -- with the intention that it only affects shells -- and by doing so it renders useless GDB's own mechanism for setting the history size via .gdbinit. Also, annoyances may arise when HISTSIZE is not interpreted the same way by the shell and by GDB, e.g. PR gdb/16999. That can always be fixed on a shell-by-shell basis but it may be impossible to be consistent with the behavior of all shells at once. Finally it just makes sense to not confound shell environment variables with application environment variables. gdb/ChangeLog: * NEWS: Mention that GDBHISTSIZE is read instead of HISTSIZE. * top.c (init_history): Read from GDBHISTSIZE instead of HISTSIZE. (init_main): Refer to GDBHISTSIZE instead of HISTSIZE. gdb/doc/ChangeLog: * gdb.texinfo (Command History): Replace occurrences of HISTSIZE with GDBHISTSIZE. gdb/testsuite/ChangeLog: * gdb.base/gdbinit-history.exp: Replace occurrences of HISTSIZE with GDBHISTSIZE. * gdb.base/readline.exp: Likewise.	11 years ago

Mike Frysinger	6362a3f875	sim: callback: add human readable strings for debugging to maps When tracing, we often want to display the human readable name for the various syscall/errno values. Rather than make each target duplicate the lookup, extend the existing maps to include the string directly, and add helper functions to look up the constants. While most targets are autogenerated (from libgloss), the bfin/cris targets have custom maps for the Linux ABI which need to be updated by hand.	11 years ago

Patrick Palka	2093d2d314	Don't truncate the history file when history size is unlimited We still do not handle "set history size unlimited" correctly. In particular, after writing to the history file, we truncate the history even if it is unlimited. This patch makes sure that we do not call history_truncate_file() if the history is not stifled (i.e. if it's unlimited). This bug causes the history file to be truncated to zero on exit when one has "set history size unlimited" in their gdbinit file. Although this code exists in GDB 7.8, the bug is masked by a pre-existing bug that's been only fixed in GDB 7.9 (PR gdb/17820). gdb/ChangeLog: * top.c (gdb_safe_append_history): Do not call history_truncate_file if the history is not stifled. gdb/testsuite/ChangeLog: * gdb.base/gdbinit-history.exp: Add test case to check that an unlimited history file does not get truncated on exit.	11 years ago

Andreas Arnez	e6c693af14	Add vector ABI tests to gnu_vector.exp So far the gnu_vector test was limited to "static" aspects of GDB's vector support, like evaluating vector-valued expressions. This patch enriches the test and adds checks for GDB's vector ABI support as well. The new checks particularly verify inferior function calls with vector arguments and GDB's handling of vector return values. The test now attempts to compile for the target's "native" architecture, such that a hardware vector ABI is used if available. Since GDB has no vector ABI support for x86 and x86_64 targets, most of the new checks are KFAILed there. gdb/testsuite/ChangeLog: * gdb.base/gnu_vector.c: Include stdarg.h and stdio.h.

Nicolas Pitre	451133cefa	gas: section name substitution sequence This patch adds the ability to automatically construct a section name based on the prior section. When gas is invoked with --sectname-subst, the occurrence of %S in a section name will be substituted by the name of the current section. For example: .macro exception_code .pushsection %S.exception [exception code here] .popsection .endm .text [code] exception_code [...] .section .init [init code] exception_code [...] The first and second exception_code invocations create the .text.exception and the .init.exception sections respectively. This is useful e.g. to discriminate between anciliary sections that are tied to .init code and can be discarded at run time when initialization is over vs anciliary sections tied to .text sections that need to stay resident. * as.c (show_usage): Document --sectname-subst.

Patrick Palka	0a75489fab	Call target_terminal_ours_for_output() before refreshing TUI's frame info In some cases tui_show_frame_info() may get called while the inferior's terminal settings are still in effect. But when we call this function we absolutely need to have our terminal settings in effect because the function is responsible for redrawing TUI's windows following a change in the selected frame or a change in the PC. If our terminal settings are not in effect, the screen does not get redrawn properly, causing temporary display artifacts (which can be fixed via ^L). This scenario happens most prominently when stepping through a program in TUI while a watchpoint is in effect. Here is an example backtrace for when tui_show_frame_info() gets called while target_terminal_is_inferior() == 1: #1 0x00000000004988ee in tui_selected_frame_level_changed_hook (level=0) #2 0x0000000000617b99 in select_frame (fi=0x18c9820) #3 0x0000000000617c3f in get_selected_frame (message=message@entry=0x0) #4 0x00000000004ce534 in update_watchpoint (b=b@entry=0x2d9a760, reparse=reparse@entry=0) #5 0x00000000004d625e in insert_breakpoints () #6 0x0000000000531cfe in keep_going (ecs=ecs@entry=0x7ffea7884ac0) #7 0x00000000005326d7 in process_event_stop_test (ecs=ecs@entry=0x7ffea7884ac0) #8 0x000000000053596e in handle_inferior_event_1 (ecs=0x7ffea7884ac0) The fix is simple: call target_terminal_ours_for_output() before calling tui_show_frame_info() in TUI's frame-changed hook, making sure to restore the original terminal settings afterwards. gdb/ChangeLog: * tui/tui-hooks.c (tui_selected_frame_level_changed_hook): Call target_terminal_ours_for_output() before calling tui_show_frame_info(), and restore the original terminal settings afterwards.	11 years ago

Mark Wielaard	d025d5e5b5	gas: Don't use frag_align but use plain padding to align .debug_aranges. out_debug_aranges uses frag_align to make sure the addresses start out aligned. Using frag_align will call frag_var[_init], which will end up calling TC_FRAG_INIT. On arm and aarch64 TC_FRAG_INIT will generate a $d mapping symbol for the .debug_aranges to show that at that point a sequence of data items starts. Such a symbol pointing into a non-allocated debug section will confuse eu-strip -g. And it seems inefficient and wrong in general to have additional mapping symbols for debug sections, which won't contain actual code in the first place. Just keep track of the aranges header size and use plain padding to align the addresses which avoids generating any mapping symbols on aarch64 and arm. Includes a testcase for aarch64 that PASS with this patch and shows the extra $d mapping symbol in .debug_aranges before. gas/ChangeLog * dwarf2dbg.c (out_header): Document EXPR->X_add_number value, out_debug_aranges depends on it.

Andrew Burgess	51f0e40d65	gdb: Rework command completion on 'tui reg'. We previously specified a few known register groups for the 'tui reg' command. Other register groups could be accessed, but only by using the 'tui reg next' command and cycling through all the groups. This commit removes the hard coded sub-commands of 'tui reg' and instead adds dynamic completion of sub-commands based on the architecturally defined register groups, giving immediate access to all available register groups. There is still the 'next' and 'prev' commands for cycling through the register groups if that's wanted. The new code maintains the ability to only enter partial names for register groups, which is something we got for free when using the standard sub-command mechanism. The register (and register group) completer has been changed to use get_current_arch rather than using the architecture of the currently selected frame. When the target is running, this is equivalent, however, when the target is not running, using get_current_arch will provide results from the default architecture. gdb/ChangeLog: * completer.c: Add arch-utils.h include. (enum reg_completer_targets): New enum. (reg_or_group_completer_1): New function containing old reg_or_group_completer, add and use new parameter to control what is completed on.
