2016-02-22gdb.trace: Fix unavailable.exp if last register happens to be PC.Marcin Kościelnicki2-1/+6
unavailable.exp executes "info registers", expecting to find at least two instances of "<unavailable>". However, it uses "<unavailable>.*<unavailable>" as the pattern, which doesn't match when the last register happens to be available (eg. PC). Change it to ".*<unavailable>.*<unavailable>.*" instead.

2016-02-18Intel MPX bound violation handlingWalfred Tedeschi18-3/+619
With Intel Memory Protection Extensions it was introduced the concept of boundary violation. A boundary violations is presented to the inferior as a segmentation fault having SIGCODE 3. This patch adds a handler for a boundary violation extending the information displayed when a bound violation is presented to the inferior. In the stop mode case the debugger will also display the kind of violation: "upper" or "lower", bounds and the address accessed. On no stop mode the information will still remain unchanged. Additional information about bound violations are not meaningful in that case user does not know the line in which violation occurred as well. When the segmentation fault handler is stop mode the out puts will be changed as exemplified below. The usual output of a segfault is: Program received signal SIGSEGV, Segmentation fault 0x0000000000400d7c in upper (p=0x603010, a=0x603030, b=0x603050, c=0x603070, d=0x603090, len=7) at i386-mpx-sigsegv.c:68 68 value = *(p + len); In case it is a bound violation it will be presented as: Program received signal SIGSEGV, Segmentation fault Upper bound violation while accessing address 0x7fffffffc3b3 Bounds: [lower = 0x7fffffffc390, upper = 0x7fffffffc3a3] 0x0000000000400d7c in upper (p=0x603010, a=0x603030, b=0x603050, c=0x603070, d=0x603090, len=7) at i386-mpx-sigsegv.c:68 68 value = *(p + len); In mi mode the output of a segfault is: *stopped,reason="signal-received",signal-name="SIGSEGV", signal-meaning="Segmentation fault", frame={addr="0x0000000000400d7c", func="upper",args=[{name="p", value="0x603010"},{name="a",value="0x603030"} ,{name="b",value="0x603050"}, {name="c",value="0x603070"}, {name="d",value="0x603090"},{name="len",value="7"}], file="i386-mpx-sigsegv.c",fullname="i386-mpx-sigsegv.c",line="68"}, thread-id="1",stopped-threads="all",core="6" in the case of a bound violation: *stopped,reason="signal-received",signal-name="SIGSEGV", signal-meaning="Segmentation fault", sigcode-meaning="Upper bound violation", lower-bound="0x603010",upper-bound="0x603023",bound-access="0x60302f", frame={addr="0x0000000000400d7c",func="upper",args=[{name="p", value="0x603010"},{name="a",value="0x603030"},{name="b",value="0x603050"}, {name="c",value="0x603070"},{name="d",value="0x603090"}, {name="len",value="7"}],file="i386-mpx-sigsegv.c", fullname="i386-mpx-sigsegv.c",line="68"},thread-id="1", stopped-threads="all",core="6" 2016-02-18 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * NEWS: Add entry for bound violation. * amd64-linux-tdep.c (amd64_linux_init_abi_common): Add handler for segmentation fault. * gdbarch.sh (handle_segmentation_fault): New. * gdbarch.c: Regenerate. * gdbarch.h: Regenerate. * i386-linux-tdep.c (i386_linux_handle_segmentation_fault): New.

2016-02-18gdb: Add guess_tracepoint_registers hook to gdbarch.Marcin Kościelnicki7-39/+95
When we're looking at a tracefile trace frame where registers are not available, and the tracepoint has only one location, we supply the location's address as the PC register. However, this only works if PC is not a pseudo register, and individual architectures may want to guess more registers. Add a gdbarch hook that will handle that. gdb/ChangeLog: * arch-utils.c (default_guess_tracepoint_registers): New function. * arch-utils.h (default_guess_tracepoint_registers): New prototype. * gdbarch.c: Regenerate. * gdbarch.h: Regenerate. * gdbarch.sh: Add guess_tracepoint_registers hook. * tracefile.c (tracefile_fetch_registers): Use the new gdbarch hook.

This patch series add fork support in target remote, [PATCH v2 0/3] Target remote mode fork and exec support https://sourceware.org/ml/gdb-patches/2015-12/msg00144.html so GDB can be informed about the child, and adjust child correctly in displaced stepping. The PR server/13796 was fixed by this patch series actually.

2016-02-18Set breakpoint condition-evaluation in forking-threads-plus-breakpoint.expYao Qi2-0/+20
Proc do_test in forking-threads-plus-breakpoint.exp has an argument cond_bp_target, but the test doesn't use it to set "breakpoint condition-evaluation", which is an oversight in the test. This patch fixes it by setting "breakpoint condition-evaluation" per $cond_bp_target. gdb/testsuite: 2016-02-18 Yao Qi <yao.qi@linaro.org> * gdb.threads/forking-threads-plus-breakpoint.exp (do_test): Set "set breakpoint condition-evaluation" per $cond_bp_target.
