GDB has five places where it pretends to stat for bfd_openr_iovec. Four of these only set the incoming buffer's st_size, leaving the other fields unchanged, which is to say very likely populated with random values from the stack. remote_bfd_iovec_stat was fixed in 0a93529c56714b1da3d7106d3e0300764f8bb81c; this commit fixes the other four. gdb/ChangeLog: * jit.c (mem_bfd_iovec_stat): Zero supplied buffer. * minidebug.c (lzma_stat): Likewise. * solib-spu.c (spu_bfd_iovec_stat): Likewise. * spu-linux-nat.c (spu_bfd_iovec_stat): Likewise.
2015-04-14Add -z noextern-protected-data to ld for ELF/x86H.J. Lu22-4/+105
Address of protected data defined in the shared library may be external, i.e., due to copy relocation. By default, linker backend checks if relocations against protected data symbols are valid for building shared library and issues an error if relocation isn't allowed. The new option override linker backend default. When -z noextern-protected-data is used, updates on protected data symbols by another module won't be visibile to the resulting shared library.

2015-04-13Add support for the x86 XSAVE extended state on FreeBSD/x86.John Baldwin16-7/+470
Recognize NT_X86_XSTATE notes in FreeBSD process cores. Recent FreeBSD versions include a note containing the XSAVE state for each thread in the process when XSAVE is in use. The note stores a copy of the current XSAVE mask in a reserved section of the machine-defined XSAVE state at the same offset as Linux's NT_X86_XSTATE note. For native processes, use the PT_GETXSTATE_INFO ptrace request to determine if XSAVE is enabled, and if so the active XSAVE state mask (that is, the value of %xcr0 for the target process) as well as the size of XSAVE state area. Use the PT_GETXSTATE and PT_SETXSTATE requests to fetch and store the XSAVE state, respectively, in the BSD x86 native targets. In addition, the FreeBSD amd64 and i386 native targets now include "read_description" target methods to determine the correct x86 target description for the current XSAVE mask. On FreeBSD amd64 this also properly returns an i386 target description for 32-bit binaries which allows the 64-bit GDB to run 32-bit binaries. Note that the ptrace changes are in the BSD native targets, not the FreeBSD-specific native targets since that is where the other ptrace register accesses occur. Of the other BSDs, NetBSD and DragonFly use XSAVE in the kernel but do not currently export the extended state via ptrace(2). OpenBSD does not currently support XSAVE. bfd/ChangeLog: * elf.c (elfcore_grok_note): Recognize NT_X86_XSTATE on FreeBSD.

This testcase seems to assume the target is running Linux, so bare metal, simulators and other debugging stubs running different OS' will have a hard time executing some of the commands the testcase issues. Even restricting the testcase to Linux systems (which the patch below does), there are still problems with, say, QEMU not providing PID information when "info inferior" is issued. As a consequence, the subsequent tests will either fail or will not make much sense. The attached patch checks if PID information is available. If not, it just bails out and avoids running into a number of failures. gdb/testsuite/ChangeLog: 2015-04-13 Luis Machado <lgustavo@codesourcery.com> * gdb.base/coredump-filter.exp: Restrict test to Linux systems only.

This commit renames the global array variable "addr" to an unique name "coredump_var_addr" in the test gdb.base/coredump-filter.exp. This is needed because global arrays can have name conflicts between tests. For example, this specific test was conflicting with dmsym.exp, causing errors like: ERROR: tcl error sourcing ../../../../../binutils-gdb/gdb/testsuite/gdb.base/dmsym.exp. ERROR: can't set "addr": variable is array while executing "set addr "0x\[0-9a-zA-Z\]+"" (file "../../../../../binutils-gdb/gdb/testsuite/gdb.base/dmsym.exp" line 45) invoked from within "source ../../../../../binutils-gdb/gdb/testsuite/gdb.base/dmsym.exp" ("uplevel" body line 1) invoked from within "uplevel #0 source ../../../../../binutils-gdb/gdb/testsuite/gdb.base/dmsym.exp" invoked from within "catch "uplevel #0 source $test_file_name"" This problem was reported by Yao Qi at: <https://sourceware.org/ml/gdb-patches/2015-04/msg00373.html> Message-Id: <1428666671-12926-1-git-send-email-qiyaoltc@gmail.com> gdb/testsuite/ChangeLog: 2015-04-13 Sergio Durigan Junior <sergiodj@redhat.com> * gdb.base/coredump-filter.exp: Rename variable "addr" to "coredump_var_addr" to avoid naming conflict with other testcases.
2015-04-13sim: fix the PKGVERSION defineMike Frysinger55-55/+164
This should be SIM, not GDB.
2015-04-13sim: options: add --version supportMike Frysinger2-0/+18
The old run frontend had a --version option, but the new common sim-options file does not. Restore support for that so we can get version info out of `run` when using the new frontend.
2015-04-13sim: switch to gdb version scriptMike Frysinger3-40/+8
Since the local create-version.sh already points directly into the gdb source tree, we might as well use the gdb script directly too.
2015-04-13sim: mn10300: convert to sim-cpuMike Frysinger4-10/+47
Make cpu allocation fully dynamic so we can leverage the common sim-cpu and its APIs.
2015-04-13sim: v850: convert to sim-cpuMike Frysinger4-9/+42
Make cpu allocation fully dynamic so we can leverage the common sim-cpu and its APIs.
2015-04-13sim: mips: convert to sim-cpuMike Frysinger4-11/+44
Make cpu allocation fully dynamic so we can leverage the common sim-cpu and its APIs.
2015-04-13sim: m68hc11: convert to sim-cpuMike Frysinger4-11/+48
Make cpu allocation fully dynamic so we can leverage the common sim-cpu and its APIs.
2015-04-13sim: mips: fix prototype warningsMike Frysinger2-63/+43
Convert a bunch of old style prototypes and tweak various casts to match the function signatures.

2015-04-13Do unset_currtarget_info ldscript for all simulator testsuites.Hans-Peter Nilsson4-6/+18
sim/testsuite: * sim-defs.exp (sim_init): Unset target ldscript here. sim/testsuite/sim/mips: * basic.exp: Don't unset target ldscript here.
2015-04-12sim: arm/mips: fix sim_read/sim_write linkage errorsMike Frysinger4-2/+11
With sim-hrw.o being built & linked in the common list, some people are getting linking errors now for these targets. Move the main objects that provide these functions before the common list to avoid that.
2015-04-12sim: ft32: delete sim_read/sim_write funcsMike Frysinger2-22/+4
The common sim-hrw.o provides both of these, so simply use them.

2015-04-11Remove --xdbJan Kratochvil22-444/+53
Pedro Alves: The commands that enables aren't even documented in the manual. Judging from that, I assume that only wdb users would ever really be using the --xdb switch. I think it's time to drop "support" for the --xdb switch too. I looked through the commands that that exposes, the only that looked potentially interesting was "go", but then it's just an alias for "tbreak+jump", which can easily be done with "define go...end". I'd rather free up the "go" name for something potentially more interesting (either run control, or maybe even unrelated, e.g., for golang). gdb/ChangeLog 2015-04-11 Jan Kratochvil <jan.kratochvil@redhat.com> * NEWS (Changes since GDB 7.9): Add removed -xdb. * breakpoint.c (command_line_is_silent): Remove xdb_commands conditional.
