Native and remote debugging are covered by this patch. New registers are bound registers known as bnd register (bnd0...bnd3), a configuration register bndcfgu and a status register bndstatus. Bound registers store pointer bounds, i.e. bound limits of a pointer. Bndstatus and bndcfgu store information of the current status and configuration of other MPX counterparts. For more information [1][2]. Design notes: Bound register are represented in hardware as two fields of 64bits each, both in 64bit and 32bit mode. The fields are lower bound and upper bound. Upper bound value is a complement of one value of the upper limiting address. To take this into account the bnd0...bnd3 are created as pseudo registers while the hardware values are stored on bnd0raw...bnd3raw. Ok to commit?

Changes between V4 and V5: * Improved text for MPX feature on gdb.texinfo following Eli indications. * Fixed one table that still had ORIG_EAX and ORIG_RAX in the middle. Changes between V3 and V4: * Added NEWS entry for MPX. * Improved text for MPX feature on gdb.texinfo. * Fixed several ChangeLogs. Changes between V2 and V3: * Small changes on changelogs: "Add MPX support for i386" and "Add support for MPX amd64". * Add MPX feature documentation as extra patch. Changes between V1 and V2: * Folowing the Mark Kettenis feedback: Orig_rax and orig_eax are left as the last register on the internal list. * Ported gcc file used for cpuid and corrected overlooked condition to detect MPX hardware while performing MPX related tests. Walfred Tedeschi (8): Fix conditions in creating a bitfield. Add MPX registers XML files. Add MPX support for i386 MPX for amd64 Add MPX support to gdbserver. Add pretty-printer for MPX bnd registers. Add MPX registers tests. Add MPX feature description to GDB manual. gdb/NEWS | 2 + gdb/amd64-linux-nat.c | 43 +++-- gdb/amd64-linux-tdep.c | 14 +- gdb/amd64-linux-tdep.h | 6 +- gdb/amd64-tdep.c | 18 +++ gdb/amd64-tdep.h | 8 +- gdb/common/i386-gcc-cpuid.h | 8 +- gdb/common/i386-xstate.h | 21 ++- gdb/data-directory/Makefile.in | 1 + gdb/doc/gdb.texinfo | 22 +++ gdb/features/Makefile | 38 ++++- gdb/features/i386/32bit-mpx.xml | 43 +++++ gdb/features/i386/64bit-mpx.xml | 43 +++++ gdb/features/i386/amd64-mpx-linux.c | 211 ++++++++++++++++++++++++ gdb/features/i386/amd64-mpx-linux.xml | 19 +++ gdb/features/i386/amd64-mpx.c | 206 +++++++++++++++++++++++ gdb/features/i386/amd64-mpx.xml | 17 ++ gdb/features/i386/i386-mpx-linux.c | 187 +++++++++++++++++++++ gdb/features/i386/i386-mpx-linux.xml | 19 +++ gdb/features/i386/i386-mpx.c | 182 +++++++++++++++++++++ gdb/features/i386/i386-mpx.xml | 17 ++ gdb/features/i386/x32-mpx-linux.c | 211 ++++++++++++++++++++++++ gdb/features/i386/x32-mpx-linux.xml | 19 +++ gdb/features/i386/x32-mpx.c | 206 +++++++++++++++++++++++ gdb/features/i386/x32-mpx.xml | 17 ++ gdb/gdbserver/Makefile.in | 15 ++ gdb/gdbserver/configure.srv | 20 +-- gdb/gdbserver/i387-fp.c | 90 +++++++++++ gdb/gdbserver/linux-x86-low.c | 87 ++++++++-- gdb/i386-linux-nat.c | 17 +- gdb/i386-linux-tdep.c | 9 +- gdb/i386-linux-tdep.h | 6 +- gdb/i386-tdep.c | 216 ++++++++++++++++++++++++- gdb/i386-tdep.h | 30 +++- gdb/i387-tdep.c | 130 ++++++++++++++- gdb/i387-tdep.h | 7 + gdb/python/lib/gdb/command/bound_registers.py | 45 ++++++ gdb/regformats/i386/amd64-mpx-linux.dat | 84 ++++++++++ gdb/regformats/i386/amd64-mpx.dat | 83 ++++++++++ gdb/regformats/i386/i386-mpx-linux.dat | 60 +++++++ gdb/regformats/i386/i386-mpx.dat | 59 +++++++ gdb/regformats/i386/x32-mpx-linux.dat | 84 ++++++++++ gdb/regformats/i386/x32-mpx.dat | 83 ++++++++++ gdb/target-descriptions.c | 2 +- gdb/testsuite/gdb.arch/i386-mpx.c | 92 +++++++++++ gdb/testsuite/gdb.arch/i386-mpx.exp | 142 ++++++++++++++++ gdb/testsuite/gdb.python/py-pp-maint.exp | 8 +- gdb/testsuite/gdb.xml/maint_print_struct.xml | 1 + 48 files changed, 2875 insertions(+), 73 deletions(-) create mode 100644 gdb/features/i386/32bit-mpx.xml create mode 100644 gdb/features/i386/64bit-mpx.xml create mode 100644 gdb/features/i386/amd64-mpx-linux.c create mode 100644 gdb/features/i386/amd64-mpx-linux.xml create mode 100644 gdb/features/i386/amd64-mpx.c create mode 100644 gdb/features/i386/amd64-mpx.xml create mode 100644 gdb/features/i386/i386-mpx-linux.c create mode 100644 gdb/features/i386/i386-mpx-linux.xml create mode 100644 gdb/features/i386/i386-mpx.c create mode 100644 gdb/features/i386/i386-mpx.xml create mode 100644 gdb/features/i386/x32-mpx-linux.c create mode 100644 gdb/features/i386/x32-mpx-linux.xml create mode 100644 gdb/features/i386/x32-mpx.c create mode 100644 gdb/features/i386/x32-mpx.xml create mode 100644 gdb/python/lib/gdb/command/bound_registers.py create mode 100644 gdb/regformats/i386/amd64-mpx-linux.dat create mode 100644 gdb/regformats/i386/amd64-mpx.dat create mode 100644 gdb/regformats/i386/i386-mpx-linux.dat create mode 100644 gdb/regformats/i386/i386-mpx.dat create mode 100644 gdb/regformats/i386/x32-mpx-linux.dat create mode 100644 gdb/regformats/i386/x32-mpx.dat create mode 100644 gdb/testsuite/gdb.arch/i386-mpx.c create mode 100644 gdb/testsuite/gdb.arch/i386-mpx.exp -- 1.7.10.4
