Intel MPX bound violation handling 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.

Rename 32- and 64-bit Intel files from "i386" to "x86" This commit renames nine files that contain code used by both 32- and 64-bit Intel ports such that their names are prefixed with "x86" rather than "i386". All types, functions and variables within these files are likewise renamed such that their names are prefixed with "x86" rather than "i386". This makes GDB follow the convention used by gdbserver such that 32-bit Intel code lives in files called "i386-*", 64-bit Intel code lives in files called "amd64-*", and code for both 32- and 64-bit Intel lives in files called "x86-*". This commit only renames OS-independent files. The Linux ports of both GDB and gdbserver now follow the i386/amd64/x86 convention fully. Some ports still use the old convention where "i386" in file/function/ type/variable names can mean "32-bit only" or "32- and 64-bit" but I don't want to touch ports I can't fully test except where absolutely necessary. gdb/ChangeLog: * i386-nat.h: Renamed as... * x86-nat.h: New file.

any other way. Therefore we only do the memory reads if no
function name could be identified, which should be the case since
the code is on the stack.
Detection of signal trampolines for handlers that set the
SA_RESTORER flag is in general not possible. Unfortunately this is
what the GNU C Library has been doing for quite some time now.
However, as of version 2.1.2, the GNU C Library uses signal
trampolines (named __restore and __restore_rt) that are identical
to the ones used by the kernel. Therefore, these trampolines are
supported too. */

Add casts for legitimate integer to enum conversions This patch is mostly extracted from Pedro's C++ branch. It adds explicit casts from integer to enum types, where it is really the intention to do so. This could be because we are ... * iterating on enum values (we need to iterate on an equivalent integer) * converting from a value read from bytes (dwarf attribute, agent expression opcode) to the equivalent enum * reading the equivalent integer value from another language (Python/Guile) An exception to that is the casts in regcache.c. It seems to me like struct regcache's register_status field could be a pointer to an array of enum register_status. Doing so would waste a bit of memory (4 bytes used by the enum vs 1 byte used by the current signed char, for each register). If we switch to C++11 one day, we can define the underlying type of an enum type, so we could have the best of both worlds. gdb/ChangeLog: * arm-tdep.c (set_fp_model_sfunc): Add cast from integer to enum.

It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value.

Intel MPX bound violation handling 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.

Intel MPX bound violation handling 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.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Intel MPX bound violation handling 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.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

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.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

uiout->field_string ("sigcode-meaning", _("Lower bound violation"));
Intel MPX bound violation handling 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.

Intel MPX bound violation handling 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.

Intel MPX bound violation handling 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.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Intel MPX bound violation handling 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.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Intel MPX bound violation handling 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.

Add AVX512 registers support to GDB and GDBserver. This patch adds support for the Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX-512) registers. Native and remote debugging are covered by this patch. Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers are aliased to the respective 256-bit YMM registers. The lower 128-bits are aliased to the respective 128-bit XMM registers. There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode and 64-bit mode. For more information please see Intel(R) Developer Zone: Intel(R) AVX http://software.intel.com/en-us/intel-isa-extensions#pid-16007-1495 Intel(R) Architecture Instruction Set Extensions Programming Reference: http://software.intel.com/en-us/file/319433-017pdf 2014-04-24 Michael Sturm <michael.sturm@mintel.com> Walfred Tedeschi <walfred.tedeschi@intel.com> * amd64-linux-nat.c (amd64_linux_gregset32_reg_offset): Add AVX512 registers.

Add support for Intel PKRU register to GDB and GDBserver. This patch adds support for the registers added by the Memory Protection Keys for Userspace (PKU aka PKEYs) feature. Native and remote debugging are covered by this patch. The XSAVE area is extended with a new state containing the 32-bit wide PKRU register. The new register is added to amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also, respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set it supports.

Add AVX512 registers support to GDB and GDBserver. This patch adds support for the Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX-512) registers. Native and remote debugging are covered by this patch. Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers are aliased to the respective 256-bit YMM registers. The lower 128-bits are aliased to the respective 128-bit XMM registers. There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode and 64-bit mode.

Rename 32- and 64-bit Intel files from "i386" to "x86" This commit renames nine files that contain code used by both 32- and 64-bit Intel ports such that their names are prefixed with "x86" rather than "i386". All types, functions and variables within these files are likewise renamed such that their names are prefixed with "x86" rather than "i386". This makes GDB follow the convention used by gdbserver such that 32-bit Intel code lives in files called "i386-*", 64-bit Intel code lives in files called "amd64-*", and code for both 32- and 64-bit Intel lives in files called "x86-*". This commit only renames OS-independent files. The Linux ports of both GDB and gdbserver now follow the i386/amd64/x86 convention fully. Some ports still use the old convention where "i386" in file/function/ type/variable names can mean "32-bit only" or "32- and 64-bit" but I don't want to touch ports I can't fully test except where absolutely necessary. gdb/ChangeLog: * i386-nat.h: Renamed as... * x86-nat.h: New file.

/* Linux kernel shows PC value after the 'int $0x80' instruction even if
inferior is still inside the syscall. On next PTRACE_SINGLESTEP it will
finish the syscall but PC will not change.
Some vDSOs contain 'int $0x80; ret' and during stepping out of the syscall
i386_displaced_step_fixup would keep PC at the displaced pad location.
As PC is pointing to the 'ret' instruction before the step
i386_displaced_step_fixup would expect inferior has just executed that 'ret'
and PC should not be adjusted. In reality it finished syscall instead and
PC should get relocated back to its vDSO address. Hide the 'ret'
instruction by 'nop' so that i386_displaced_step_fixup is not confused.
It is not fully correct as the bytes in struct displaced_step_closure will
not match the inferior code. But we would need some new flag in
displaced_step_closure otherwise to keep the state that syscall is finishing
for the later i386_displaced_step_fixup execution as the syscall execution
is already no longer detectable there. The new flag field would mean
i386-linux-tdep.c needs to wrap all the displacement methods of i386-tdep.c
which does not seem worth it. The same effect is achieved by patching that
'nop' instruction there instead. */

Create a displaced_step_closure class hierarchy displaced_step_closure is a type defined in multiple -tdep.c files. Trying to xfree it from the common code (infrun.c) is a problem when we try to poison xfree for non-POD types. Because there can be multiple of these types in the same build, this patch makes a hierarchy of classes with a virtual destructor. When the common code deletes the object through a displaced_step_closure pointer, it will invoke the right destructor. The amd64 used a last-member array with a variable size. That doesn't work with new, so I changed it for an std::vector. Other architectures which used a simple byte buffer as a closure now use a shared buf_displaced_step_closure, a closure type that only contains a gdb::byte_vector. Reg-tested on the buildbot. gdb/ChangeLog: * infrun.h: Include common/byte-vector.h. (struct displaced_step_closure): New struct.

PR13858 - Can't do displaced stepping with no symbols Running break-interp.exp with the target always in non-stop mode trips on PR13858, as enabling non-stop also enables displaced stepping. The problem is that when GDB doesn't know where the entry point is, it doesn't know where to put the displaced stepping scratch pad. The test added by this commit exercises this. Without the fix, we get: (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: break *$pc set displaced-stepping on (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: set displaced-stepping on stepi 0x00000000004005be in ?? () Entry point address is not known. (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: stepi p /x $pc $2 = 0x4005be (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: get after PC FAIL: gdb.base/step-over-no-symbols.exp: displaced=on: advanced The fix switches all GNU/Linux ports to get the entry point from AT_ENTRY in the target auxiliary vector instead of from symbols. This is currently only done by PPC when Cell debugging is enabled, but I think all archs should be able to do the same. Note that ppc_linux_displaced_step_location cached the result, I'm guessing to avoid constantly re-fetching the auxv out of remote targets, but that's no longer necessary nowadays, as the auxv blob is itself cached in the inferior object. The ppc_linux_entry_point_addr global is obviously bad for multi-process too nowadays. Tested on x86-64 (-m64/-m32), PPC64 (-m64/-m32) and S/390 GNU/Linux.

/* Functions for 'catch syscall'. */
Partial fix for PR breakpoints/10737: Make syscall info be per-arch instead of global This patch intends to partially fix PR breakpoints/10737, which is about making the syscall information (for the "catch syscall" command) be per-arch, instead of global. This is not a full fix because of the other issues pointed by Pedro here: <https://sourceware.org/bugzilla/show_bug.cgi?id=10737#c5> However, I consider it a good step towards the real fix. It will also help me fix <https://sourceware.org/bugzilla/show_bug.cgi?id=17402>. What this patch does, basically, is move the "syscalls_info" struct to gdbarch. Currently, the syscall information is stored in a global variable inside gdb/xml-syscall.c, which means that there is no easy way to correlate this info with the current target or architecture being used, for example. This causes strange behaviors, because the syscall info is not re-read when the arch changes. For example, if you put a syscall catchpoint in syscall 5 on i386 (syscall open), and then load a x86_64 program on GDB and put the same syscall 5 there (fstat on x86_64), you will still see that GDB tells you that it is catching "open", even though it is not. With this patch, GDB correctly says that it will be catching fstat syscalls. (gdb) set architecture i386 The target architecture is assumed to be i386 (gdb) catch syscall 5 Catchpoint 1 (syscall 'open' [5]) (gdb) set architecture i386:x86-64 The target architecture is assumed to be i386:x86-64 (gdb) catch syscall 5 Catchpoint 2 (syscall 'open' [5]) But with the patch: (gdb) set architecture i386 The target architecture is assumed to be i386 (gdb) catch syscall 5 Catchpoint 1 (syscall 'open' [5]) (gdb) set architecture i386:x86-64 The target architecture is assumed to be i386:x86-64 (gdb) catch syscall 5 Catchpoint 2 (syscall 'fstat' [5]) As I said, there are still some problems on the "catch syscall" mechanism, because (for example) the user should be able to "catch syscall open" on i386, and then expect "open" to be caught also on x86_64. Currently, it doesn't work. I intend to work on this later. gdb/ 2014-11-20 Sergio Durigan Junior <sergiodj@redhat.com> PR breakpoints/10737 * amd64-linux-tdep.c (amd64_linux_init_abi_common): Adjust call to set_xml_syscall_file_name to provide gdbarch. * arm-linux-tdep.c (arm_linux_init_abi): Likewise. * bfin-linux-tdep.c (bfin_linux_init_abi): Likewise. * breakpoint.c (print_it_catch_syscall): Adjust call to get_syscall_by_number to provide gdbarch.

Intel MPX bound violation handling 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.
