2016-07-01Consolidate x86 debug register code for BSD native targets.John Baldwin6-7/+7
Move the debug register support code from amd64bsd-nat.c and i386bsd-nat.c into a shared x86bsd-nat.c. Instead of setting up x86_dr_low in amd64fbsd-nat.c and i386fbsd-nat.c, add a x86bsd_target function that creates a new target that inherits from inf_ptrace and sets up x86 debug registers if supported. In addition to initializing x86_dr_low, the x86bsd target installs a custom mourn_inferior target operation to clean up the x86 debug register state. Previously this was only done on amd64. Now it will be done for both i386 and amd64. The i386bsd_target and amd64bsd_target functions create targets that inherit from x86bsd rather than inf_ptrace. gdb/ChangeLog: * Makefile.in [HFILES_NO_SRCDIR]: Replace 'amd64bsd-nat.h' with 'x86bsd-nat.h'. * amd64bsd-nat.c: Include 'x86bsd-nat.h' instead of 'amd64bsd-nat.h'.

2016-01-21Fix regression introduced in "break *<EXPR>" by explicit location patches.Joel Brobecker1-0/+2
A relatively recent patch support for explicit locations, and part of that patch cleaned up the way we parse breakpoint locations. Unfortunatly, a small regression crept in for "*<EXPR>" breakpoint locations. In particular, on PIE programs, one can see the issue by doing the following, with any program: (gdb) b *main Breakpoint 1 at 0x51a: file hello.c, line 3. (gdb) run Starting program: /[...]/hello Error in re-setting breakpoint 1: Warning: Cannot insert breakpoint 1. Cannot access memory at address 0x51a Warning: Cannot insert breakpoint 1. Cannot access memory at address 0x51a Just for the record, this regression was introduced by: commit a06efdd6effd149a1d392df8d62824e44872003a Date: Tue Aug 11 17:09:35 2015 -0700 Subject: Explicit locations: introduce address locations What happens is that the patch makes the implicit assumption that the address computed the first time is static, as if it was designed to only support litteral expressions (Eg. "*0x1234"). This allows the shortcut of not re-computing the breakpoint location's address when re-setting breakpoints. However, this does not work in general, as demonstrated in the example above. This patch plugs that hole simply by saving the original expression used to compute the address as part of the address location, so as to then re-evaluate that expression during breakpoint re-set. gdb/ChangeLog: * location.h (new_address_location): Add new parameters "addr_string" and "addr_string_len". (get_address_string_location): Add declaration. * location.c (new_address_location): Add new parameters "addr_string" and "addr_string_len". If not NULL, store a copy of the addr_string in the new location as well. (get_address_string_location): New function. (string_to_event_location): Update call to new_address_location. * linespec.c (event_location_to_sals) <ADDRESS_LOCATION>: Save the event location in the parser's state before passing it to convert_address_location_to_sals. * breakpoint.c (create_thread_event_breakpoint): Update call to new_address_location.

2015-07-17Move common aarch64 HW breakpoint/watchpoint code to nat/Yao Qi1-1/+1
When I look at test fails related to watchpoint on aarch64-linux, I find there are some code duplicates between GDB and GDBserver. This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}. The only change I do is about the dr_changed_t typedef, which was ULONGEST in GDB and 'unsigned long long' in GDBserver. Each bit of dr_changed_t represents a status of each HW breakpoint or watchpoint register, and the max number of HW breakpoint or watchpoint registers is 16, so the width of 'unsigned long long' is sufficient. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * Makefile.in (HFILES_NO_SRCDIR): Add nat/aarch64-linux-hw-point.h.

2015-07-07Native debug arm program by aarch64 GDBYao Qi1-1/+1
This patch is to let aarch64 GDB debug 32-bit arm program natively. In each function for fetching and storing registers, GDB will check gdbarch_bfd_arch_info (gdbarch)->bits_per_word, if it is 32, call the corresponding aarch32 functions in aarch32-linux-nat.c, otherwise fall back to aarch64 code to fetch and store registers. aarch64_linux_read_description has to return the right target description, but we don't have gdbarch available there, so GDB fetches auxv and gets AT_PHENT, in order to determine whether the target is 32-bit or 64-bit.

2015-03-13Remove HPUXJan Kratochvil3-8/+0
IIUC it is a pre-requisite for IPv6 support, some UNICes do not support getaddrinfo required for IPv6. But coincidentally such UNICes are no longer really supported by GDB. Therefore it was concluded we can remove all such UNICes and then we can implement IPv6 easily with getaddrinfo. In mail Re: getaddrinfo available on all GDB hosts?

2015-01-15Move code to disable ASR to nat/Sergio Durigan Junior18-14/+23
This patch moves the shared code present on gdb/linux-nat.c:linux_nat_create_inferior and gdb/gdbserver/linux-low.c:linux_create_inferior to nat/linux-personality.c. This code is responsible for disabling address space randomization based on user setting, and using <sys/personality.h> to do that. I decided to put the prototype of the maybe_disable_address_space_randomization on nat/linux-osdata.h because it seemed the best place to put it.

2015-01-14Detect 64-bit-ness in PowerPC Book III-EYao Qi1-1/+1
This patch is to teach both GDB and GDBServer to detect 64-bit inferior correctly. We find a problem that GDBServer is unable to detect on a e5500 core processor. Current GDBServer assumes that MSR is a 64-bit register, but MSR is a 32-bit register in Book III-E. This patch is to fix this problem by checking the right bit in MSR, in order to handle both Book III-S and Book III-E. In order to detect Book III-S and Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by getauxval on glibc >= 2.16. If getauxval doesn't exist, we implement the fallback by parsing /proc/self/auxv), because it should an invariant on the same machine cross different processes. In order to share code, I add nat/ppc-linux.c for both GDB and GDBserver side. gdb: 2015-01-14 Yao Qi <yao@codesourcery.com> * Makefile.in (ppc-linux.o): New rule. * config/powerpc/ppc64-linux.mh (NATDEPFILES): Add ppc-linux.o. * configure.ac: AC_CHECK_FUNCS(getauxval). * config.in: Re-generated. * configure: Re-generated. * nat/ppc-linux.h [__powerpc64__] (ppc64_64bit_inferior_p): Declare. * nat/ppc-linux.c: New file. * ppc-linux-nat.c (ppc_linux_target_wordsize) [__powerpc64__]: Call ppc64_64bit_inferior_p. gdb/gdbserver: 2015-01-14 Yao Qi <yao@codesourcery.com> * Makefile.in (SFILES): Add nat/ppc-linux.c.

2014-11-28Remove (dead-code) native core file sniffers on Linux targetsUlrich Weigand3-3/+2
Since Andreas Arnez' recent patch series, all Linux targets install gdbarch_iterate_over_regset_sections routines. This means that on Linux native targets, old-style core sniffers are never used. Most Linux targets haven't been using such sniffers for a long time anyway, but a couple remain: ia64 and sparc use core-regset.o, and m68k installs its own core_fns. All this is now dead code, which this commit removes. gdb/ 2014-11-28 Ulrich Weigand  <uweigand@de.ibm.com> * config/ia64/linux.mh (NATDEPFILES): Remove core-regset.o. * config/sparc/linux.mh (NATDEPFILES): Likewise. * config/sparc/linux64.mh (NATDEPFILES): Likewise. * m68klinux-nat.c (fetch_core_registers): Remove.

2014-10-17Delete Tru64 supportPedro Alves3-45/+0
This commit does most of the mechanical removal. IOW, the easy part. procfs.c isn't touched beyond removing a couple obvious bits that are guarded by a couple macros defined in config/alpha/nm-osf3.h. Going beyond that for procfs.c & co would be a harder excision that potentially affects Solaris. Some comments in the generic alpha code ABIs that may still be relevant and I wouldn't know what to do with them. That can always be done on a separate pass, preferably by someone who can test on alpha. A couple other spots have references to OSF/Tru64 and related files being removed, but it felt like removing them would make things worse, not better. We can revisit those when we next need to touch that code. I didn't remove a reference to osf in testsuite/lib/future.exp, as I believe that code is imported from DejaGNU. Built and tested on x86_64 Fedora 20, with --enable-targets=all.

2014-09-02Rename 32- and 64-bit Intel files from "i386" to "x86"Gary Benson10-10/+10
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.

2013-10-30S/390: Rename source files to *-linux-*Ulrich Weigand1-1/+1
As suggested before, rename the S/390-related source files (tdep and nat) such that "-linux-" occurs in the file name, like with other GNU/Linux targets. Since no other operating system is currently supported by GDB on this architecture, this isn't strictly necessary. But the old names sometimes caused GDB contributors to miss these files when performing a change that affects all GNU/Linux targets. The latest such incident was observed here: https://sourceware.org/ml/gdb-patches/2013-09/msg00619.html gdb/ 2013-10-30 Andreas Arnez <arnez@linux.vnet.ibm.com> * s390-tdep.h: Rename to... * s390-linux-tdep.h: ...here. * s390-tdep.c: Rename to... * s390-linux-tdep.c: ...here.

2013-10-25Make STARTUP_WITH_SHELL a runtime toggle -- add new "set/show ↵Pedro Alves1-4/+5
startup-with-shell" option. Occasionaly we hear about people having problems with GDB not being able to start programs (with "run"/"start"). GDB spawns a shell to start the program, and most often, it'll be the case that the problem is actually with the user's shell setup. GDB has code to disable the use of the shell to start programs. That's the STARTUP_WITH_SHELL macro that native targets could set to 0 in their nm.h file (though no target actually uses it nowadays). This patch makes that setting a run-time knob instead. This will be useful to quickly diagnose such shell issues, and might also come in handy at other times (such as when debugging the shell itself, if you don't have a different shell handy). gdb/ 2013-10-24 Pedro Alves <palves@redhat.com> * NEWS (New options): Mention set/show startup-with-shell. * config/alpha/nm-osf3.h (START_INFERIOR_TRAPS_EXPECTED): Set to 2 instead of 3. * fork-child.c (fork_inferior, startup_inferior): Handle 'set startup-with-shell'.

2013-07-01Normalize on PATH_MAX instead of MAXPATHLEN throughout.Pedro Alves1-4/+0
With the pathmax gnulib module in place, we can use PATH_MAX consistently throughout, instead of the current mixbag of PATH_MAX and MAXPATHLEN uses. It's no longer necessary to include sys/param.h (supposedly, I can't check all ports touched here) for MAXPATHLEN. Don't remove sys/param.h from GDB's configure.ac, as later tests in the file use HAVE_SYS_PARAM_H checks. Tested on x86_64 Fedora 17. Also cross-built for --host=i686-w64-mingw32, and --host=i586-pc-msdosdjgpp. gdb/ 2013-07-01 Pedro Alves <palves@redhat.com> * defs.h: Include "pathmax.h". * utils.c: Don't include sys/param.h.
