2015-06-15gas: Don't use frag_align but use plain padding to align .debug_aranges.Mark Wielaard5-2/+55
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.

2015-06-13gdb: Rework command completion on 'tui reg'.Andrew Burgess7-101/+232
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. Use get_current_arch rather than architecture of currently selected frame. (reg_or_group_completer): Call new reg_or_group_completer_1. (reggroup_completer): Call new reg_or_group_completer_1. * completer.h (reggroup_completer): Add declaration. * tui/tui-regs.c: Add 'completer.h' include. (tui_reg_next_command): Renamed to...

2015-06-12target: consider addressable unit size when reading/writing memorySimon Marchi3-14/+65
If we are reading/writing from a memory object, the length represents the number of "addresses" to read/write, so the addressable unit size needs to be taken into account when allocating memory on gdb's side. gdb/ChangeLog: * target.c (target_read): Consider addressable unit size when reading from a memory object.

This patch fixes the "Format string required" error when trying to print a dprintf on a now resolved, pending location when set via the MI interface even if the format string is entered correctly.

2015-06-12sim: moxie: use new common trace definesMike Frysinger2-4/+14
Now that there's common helpers for printing trace data, switch to that to restore the insn tracing support for this target.
2015-06-12sim: trace: add common macros for logging infoMike Frysinger8-37/+74
The Blackfin port had some TRACE_xxx macros for easily logging trace data. Use these as a base for common ones that have a simple form and match the existing sets of helper macros.
2015-06-12sim: mips: switch to common WITH_TRACE_ANY_PMike Frysinger4-30/+36
We want to add new common trace helpers including "TRACE", so change the mips one to the new WITH_TRACE_ANY_P macro since they do the same thing.
2015-06-12sim: trace: add WITH_TRACE_ANY_P helperMike Frysinger4-8/+19
We have STRACE_ANY_P and TRACE_ANY_P, so add WITH_TRACE_ANY_P to fill out the API. This lets us wrap the internal configure symbol.
2015-06-12sim: moxie: rename TRACE to MOXIE_TRACE_INSNMike Frysinger2-73/+79
We want to add new common trace helpers including "TRACE", so rename the moxie one to MOXIE_TRACE_INSN. This also matches what the code is doing.

2015-06-12sim: cgen: namespace custom trace functionsMike Frysinger43-7039/+7143
The cgen code declares some macros/funcs using the trace_xxx prefix, but the code isn't generic and only works with cgen targets. This is blocking the creation of new common trace functions. Let's blindly add cgen_xxx prefixes to all these symbols. Some already use this convention to avoid conflicts, so it makes sense to align them. In the future we might want to move some to the common trace core, but one thing at a time.
2015-06-12Fix broken GDB build after adding Bound table support for i386.Walfred Tedeschi4-2/+17
Types used for some variables could not be used for 32 bits, causing a compilation failure. This patch adds a cast to force a quite compilation, but at the same time it bails out in the case that the cast performed is not safe, i.e. in the case where the debuggee is 64bit and debugger is 32bit. Documentation was also affected, once a different version of texinfo the docs could not be build. 2015-06-10 Walfred Tedeschi <walfred.tedeschi@intel.com> * i386-tdep.c (i386_mpx_get_bt_entry): Add a cast for mpx_bd_mask and bt_mask to CORE_ADDR. doc: * gdb.textinfo (i386): Fix "@end table" end and "@table" placement.

2015-06-11Fix bug where SECTIONS clause does not handle compressed debug sections.Cary Coutant4-12/+33
When laying out .debug_* sections, we translate the names of compressed debug sections that start with ".zdebug", but when processing input section specs in a linker script, we do not handle the translation there.

2015-06-11sim: msp430: delete unused trace macrosMike Frysinger2-48/+6
These macros were copied from the Blackfin port but never used, so delete them as part of the trace unification work.
2015-06-11sim: trace: centralize the system tracingMike Frysinger4-17/+14
First we convert the ETRACE_P to STRACE_EVENTS_P. This means we move from using the sim_events.trace storage to the common sim_state_base.trace_data array. With that deleted, the common trace init code can be simplified so the sim state works the same as the sim cpu.
2015-06-11sim: trace: add STRACE_xxx_P macrosMike Frysinger2-0/+21
These are the parallel to the TRACE_xxx_P macros and fill out the full set to match the existing debug one.
2015-06-11sim: trace: use existing defines for the useful maskMike Frysinger2-4/+5
No point in duplicating the shift logic when we have macros already to keep that all unified.
2015-06-11sim: trace: create a common WITH_TRACE_P macroMike Frysinger2-19/+28
This way we can use the IDX macros everywhere and not worry about the encoding of the WITH_TRACE define in multiple places.
2015-06-11sim: frv: drop custom debug maskMike Frysinger2-5/+4
This is the only sim that sets up its own WITH_TRACE mask and it conflicts with the user setting their own list at configure time. Drop it to match all the other sims.
2015-06-11sim: m68hc11: delete unused interrupt_namesMike Frysinger2-8/+4

This code already matched the common sim reusme logic, so we can simply drop it and pull in the common code.

The syscall path was the only code checking the custom exception state after recent cleanups. Once we change that to the common engine halt function, we can delete that state entirely. This also helps highlight some other dead code that we can cull.
