2015-03-15sim: dv-sockser: push module init prototype downMike Frysinger2-1/+6
Pull out the duplicated dv_sockser_install prototype from the tconfig.in files and put it in the one place it gets used -- sim-module.c. This is still arguably incorrect, but it's better than the status quo where the tconfig.in has to include header files and duplicate the dv-sockser func. The tconfig header is meant to be simple and contain a target defines.

2015-02-20S390: Support new vector register sectionsAndreas Arnez2-0/+9
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15 include the existing 64-bit wide floating point registers. The Linux kernel presents the vector registers as two additional register sets, one for the right halves of v0-v15 and another one for the full registers v16-v31. Thus a new core file may contain two new register note sections, and this patch adds support to binutils for them. bfd/ * elf-bfd.h (elfcore_write_s390_vxrs_low): Add prototype.

2015-02-14PR ld/17973 LTO file symsAlan Modra2-3/+5
LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

2014-12-12add gcc/gdb interface filesTom Tromey4-0/+552
The gcc plugin is split into two parts. One part is an ordinary gcc plugin. The other part is a shared library that is loaded by gdb. This patch adds some files that define the interface exported by this shared library to gdb. These files also define the internal API by which the gdb- and gcc-sides communicate. These files will be kept in sync between gcc and gdb like much of include/. The exported API has been intentionally kept very simple. In particular only a single function is exported from the gdb-side library; symbol visibility is used to hide everything else. This exported symbol is a function which is called to return a structure holding function pointers that gdb then uses. This structure is versioned so that changes can be made without necessarily requiring a simultaneous gdb upgrade. Note that the C compiler API is broken out separately. This lets us extend it to other GCC front ends as desired. We plan to investigate C++ in the future. include/ChangeLog 2014-12-12 Phil Muldoon <pmuldoon@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Tom Tromey <tromey@redhat.com> * gcc-c-fe.def: New file. * gcc-c-interface.h: New file. * gcc-interface.h: New file.

2014-12-03callback.h:struct host_callback_struct compilation error on Windows hosts.Joel Brobecker2-3/+10
On Windows, a recent gnulib update imported the lstat module, and this caused a remote-sim.c build failure in struct host_callback_struct: In file included from /[...]/gdb/remote-sim.c:34:0: /[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64' int (*lstat) (host_callback *, const char *, struct stat *); ^ What happens it that gnulib's stat.h makes the following defines: /* Large File Support on native Windows. */ #if 1 # define stat _stati64 #endif and then: #if 1 # if ! 0 /* mingw does not support symlinks, therefore it does not have lstat. But without links, stat does just fine. */ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define lstat stat # endif So, the following fields in struct host_callback_struct... int (*stat) (host_callback *, const char *, struct stat *); int (*fstat) (host_callback *, int, struct stat *); int (*lstat) (host_callback *, const char *, struct stat *); ... get translated to... int (*_stati64) (host_callback *, const char *, struct _stati64 *); int (*_fstati64) (host_callback *, int, struct _stati64 *); int (*_stati64) (host_callback *, const char *, struct _stati64 *); ... which causes two fields to have the same name. This patch fixes the issue by renaming the stat-related fields by adding a "to_" prefix, similar to what is done in GDB's target_ops vector. include/gdb/ChangeLog: * callback.h (struct host_callback_struct) <to_stat>: Renamed from "stat". <to_fstat>: Renamed from "fstat". <to_lstat>: Renamed from "lstat". sim/common/ChangeLog: * sim-io.c (sim_io_stat, sim_io_fstat): Adjust calls to "stat" and "fstat" callbacks by calls to "to_stat" and "to_fstat" (resp) callbacks following renaming in callback.h. * syscall.c (cb_syscall): Likewise.

2014-10-17opcodes, elf: annotate instructions with HWCAP2_VIS3B.Jose E. Marchesi4-2/+10
This patch annotates the following SPARC instructions as VIS3B instructions: ldx *, %efsr, fpadd64, fpsub64, fpcmpule8, fpcmpune8, fpcmpugt8, fpcmpueq8. It also improves the documentation of the VIS3B capability in several headers. Tested in sparc64-unknown-linux-gnu and sparc-unknown-linux-gnu. No visible regressions. opcodes/ChangeLog: 2014-10-17 Jose E. Marchesi <jose.marchesi@oracle.com> * sparc-opc.c (sparc-opcodes): Annotate several instructions with the HWCAP2_VIS3B hwcap. include/opcodes/ChangeLog: 2014-10-17 Jose E.

Add the relocation numbers defined in ABI release 1.0 but missing from the current header. This will allow tools like objdump to dump objects that use these relocations. include/elf/ChangeLog: 2014-10-08 Will Newton <will.newton@linaro.org> * aarch64.h: Sync up relocations with ABI release 1.0.
2014-09-16NDS32: Code refactoring of relaxation.Kuan-Lin Chen2-7/+28
Refactor each relaxation pattern to raise the maintainability. In origin, all patterns is analysed in nds32_elf_relax_section, so it is hard to debug and maintain. Therefore, we classify all patterns into different functions in this patch. Moreover, we adjust all optimizations into nds32_elf_relax_section to take these optimizations in turn. This can promise all relaxation being done after calling gld${EMULATION_NAME}_after_allocation.
