2013-11-11PowerPC64 ELFv2, allocate dynreloc space for ifuncAlan Modra2-2/+5

2013-11-11Correct elf64-ppc.c handling of protected symbolsAlan Modra2-14/+21
Some places in elf64-ppc.c carelessly used SYMBOL_CALLS_LOCAL when the proper test is SYMBOL_REFERENCES_LOCAL for cases where we take the address of a protected symbol. This works OK for function descriptors but not for ELFv2. Setting symbols to their global entry stub a little earlier is to ensure _bfd_elf_hash_symbol allows such symbols in .gnu.hash. * elf64-ppc.c (ppc64_elf_edit_toc): Use SYMBOL_REFERENCES_LOCAL here, not SYMBOL_CALLS_LOCAL. (ppc64_elf_relocate_section): Likewise. (size_global_entry_stubs): Set undefined symbols on their global entry stubs here.. (build_global_entry_stubs): ..rather than here. (ppc64_elf_build_stubs): Don't reset glink->size before calling build_global_entry_stubs.

2013-11-08remove unused gdbserver configuryTom Tromey4-94/+11
This updates gdbserver's configure.ac to remove checks that aren't directly needed by gdbserver. 2013-11-08 Tom Tromey <tromey@redhat.com> * configure, config.in: Rebuild. * configure.ac: Remove unused configury.
2013-11-08fix a comment in configure.acTom Tromey3-6/+8
My grepping around showed that HAVE_MULTIPLE_PROC_FDS is only ever mentioned in a comment in configure.ac. Since the macro is long dead, let's remove the last mention. 2013-11-08 Tom Tromey <tromey@redhat.com> * configure: Rebuild. * configure.ac: Remove mentions of HAVE_MULTIPLE_PROC_FDS.
2013-11-08gdb configure updatesTom Tromey4-252/+22
Now that the configury needed for the "common" and "target" directories is in common.m4, some code in gdb's configure.ac is redundant. I ran this script after making an "ID" file using mkid: sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in | while read x; do echo ===== $x gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/' done This finds all the spots using HAVE_ defines, and, more importantly, makes it clear which defines aren't used in the main parts of gdb. From this I came up with this patch to remove all the unused bits. There are a few that are subtly used -- for example the configure script sometimes checks internal configure cache variables, meaning some checks cannot be removed. 2013-11-08 Tom Tromey <tromey@redhat.com> * configure, config.in: Rebuild. * configure.ac: Remove unused configury.
2013-11-08use gdb_string.h in m32c-tdep.cTom Tromey2-4/+5
m32c-tdep.c is the last user of HAVE_STRING_H in gdb proper. It really ought to be using gdb_string.h instead, as the rest of gdb does. 2013-11-08 Tom Tromey <tromey@redhat.com> * m32c-tdep.c: Use gdb_string.h.
2013-11-08remove link.h checksTom Tromey4-266/+5
The removal of solib-sunos.c also removed the last user of various macros defined by configure. This patch removes the corresponding configure code. 2013-11-08 Tom Tromey <tromey@redhat.com> * configure, config.in: Rebuild. * configure.ac: Remove all link.h-related checks.
2013-11-08introduce common.m4Tom Tromey10-0/+1178
It has bothered me for a while that files in common/ use macros defined via autoconf checks, but rely on each configure.ac doing the proper checks independently. This patch introduces common/common.m4 which consolidates the checks assumed by code in common. The rule I propose is that if something is needed or used by common, it should be checked for by common.m4. However, if the check is also needed by gdb or gdbserver, then it should be duplicated there. Built and regtested on x86-64 Fedora 18 (though this is hardly the most strenuous case) and using the Fedora 18 mingw cross compilers. I also examined the config.in diffs to ensure that symbols did not go missing. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4. * common/common.m4: New file. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4, codeset.m4. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON.

2013-11-08constify to_detachTom Tromey26-38/+67
This patch constifies the target_ops method to_detach. This is a small cleanup, but also, I think, a bug-prevention fix, since gdb already acts as if the "args" argument here was const. In particular, top.c:quit_force calls kill_or_detach via iterate_over_inferiors. kill_or_detach calls target_detach, passing the same argument each time. So, if one of these methods was not const-correct, then kill_or_detach would change its behavior in a strange way. I could not build every target I modified in this patch. I've inspected them all by hand, though. Many targets do not use the "args" parameter; a couple pass it to atoi; and a few pass it on to the to_detach method of the target beneath. The only code that required a real change was in linux-nat.c, and that only needed the introduction of a temporary variable for const-correctness. 2013-11-08 Tom Tromey <tromey@redhat.com> * aix-thread.c (aix_thread_detach): Update. * corelow.c (core_detach): Update. * darwin-nat.c (darwin_detach): Update. * dec-thread.c (dec_thread_detach): Update. * gnu-nat.c (gnu_detach): Update. * go32-nat.c (go32_detach): Update. * inf-ptrace.c (inf_ptrace_detach): Update. * inf-ttrace.c (inf_ttrace_detach): Update. * linux-fork.c (linux_fork_detach): Update. * linux-fork.h (linux_fork_detach): Update. * linux-nat.c (linux_nat_detach): Update.

2013-11-06S390: Fix TDB regset recognitionAndreas Arnez4-20/+44
When checking for the presence of the TDB regset, the current code interprets ENODATA from PTRACE_GETREGSET as an indication that the TDB regset *could* occur on this system, but the inferior stopped outside a transaction. However, the Linux kernel actually reports ENODATA even on systems without the transactional execution facility. Thus the logic is now changed to check the TE field in the HWCAP as well. This version also checks the existence of the TDB regset -- just to be on the safe side when running on TE-enabled hardware with a kernel that does not offer the TDB regset for some reason. gdb/ * s390-linux-nat.c (s390_read_description): Consider the TE field in the HWCAP for determining 'have_regset_tdb'. gdbserver/ * linux-s390-low.c (HWCAP_S390_TE): New define.
