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.

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.

zeroed debug registers.
GDB core assumes the child inherits the watchpoints/hw

Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct.

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.

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.

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.

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.

/* No MPX, PKU on x32, fall back to AVX-AVX512. */
Add target description for avx-avx512. Add a dedicated target description for the feature combination avx-avx512 as implemented by certain IA CPU models. The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers displayed as undefined on CPUs that only implemented X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue. This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * amd64-linux-tdep.c (features/i386/amd64-avx-avx512-linux.c): New include.

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 target description for avx-avx512. Add a dedicated target description for the feature combination avx-avx512 as implemented by certain IA CPU models. The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers displayed as undefined on CPUs that only implemented X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue. This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * amd64-linux-tdep.c (features/i386/amd64-avx-avx512-linux.c): New include.

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.

Add target descriptions for AVX + MPX The current MPX target descriptions assume that MPX is always combined with AVX, however that's not correct. We can have machines with MPX and without AVX; or machines with AVX and without MPX. This patch adds new target descriptions for machines that support both MPX and AVX, as duplicates of the existing MPX descriptions.

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.

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 target description for avx-avx512. Add a dedicated target description for the feature combination avx-avx512 as implemented by certain IA CPU models. The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers displayed as undefined on CPUs that only implemented X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue. This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is replaced by x32-avx-avx512.

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.

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.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands.

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.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands. It is given as argument to the "record btrace" command when starting recording. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (XMLFILES): Add btrace-conf.dtd. * x86-linux-nat.c (x86_linux_enable_btrace): Update parameters.

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.
