2015-07-20Make binutils abort message GDB friendlyH.J. Lu3-8/+8
We used to generate abort messages like: internal error, aborting at .../bfd/elf64-x86-64.c line 1554 in elf_x86_64_check_relocs We can't cut and paste "file line ???" to GDB. This patch changes those abort messages to internal error, aborting at .../bfd/elf64-x86-64.c:1554 in elf_x86_64_check_relocs so that we can cut and paste "file:???" to GDB. bfd/ * bfd.c (_bfd_abort): Replace " line " with ":" in output message. gas/ * messages.c (as_assert): Replace " line " with ":" in output message.

2015-07-20ALIGN change affects cris scriptsAlan Modra3-4/+12

2015-07-17Move common aarch64 HW breakpoint/watchpoint code to nat/Yao Qi10-1218/+767
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.

2015-07-17Pass aarch64_debug_reg_state to functionsYao Qi4-53/+72
Some functions on handling HW watchpoint in GDB and GDBserver looks the same except the code getting debug register state from current inferior. In GDB, we get debug register state like this: state = aarch64_get_debug_reg_state (ptid_get_pid (inferior_ptid)); while in GDBserver, we get debug register state like this: state = aarch64_get_debug_reg_state (); This patch is to move two lines above out of some functions, and pass aarch64_debug_reg_state to these functions, in this way, these functions are the same, and can be moved to a common place. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * aarch64-linux-nat.c (aarch64_handle_breakpoint): Add argument state and don't call aarch64_get_debug_reg_state.

2015-07-17Use debug_printf to print debug messageYao Qi4-40/+50
Some functions in aarch64-linux-nat.c and linux-aarch64-low.c looks the same except for the code printing debug message. In GDB, we use fprintf_unfiltered (gdb_stdlog, ...) while in GDBserver, we use fprintf (stderr, ...). This patch is to change them to use debug_printf so that these functions are the same, and I can move them to a common place in the following patch. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * aarch64-linux-nat.c (aarch64_show_debug_reg_state): Use debug_printf.

2015-07-17Call ptid_get_pid instead of get_thread_id in ↵Yao Qi2-1/+6
aarch64_linux_get_debug_reg_capacity aarch64_linux_get_debug_reg_capacity is called by aarch64_linux_child_post_startup_inferior, and argument ptid is created in inf-ptrace.c:inf_ptrace_create_inferior, /* On some targets, there must be some explicit actions taken after the inferior has been started up. */ target_post_startup_inferior (pid_to_ptid (pid)); so in aarch64_linux_get_debug_reg_capacity, we can get pid by ptid_get_pid, and don't need to use get_thread_id. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * aarch64-linux-nat.c (aarch64_linux_get_debug_reg_capacity): Call ptid_get_pid instead of get_thread_id.

2015-07-16Fix gdb.arch/i386-biarch-core.exp FAIL on i386.Jan Kratochvil2-9/+26
This new test fails on i686 buildbot slaves, (gdb) core-file /home/gdb-buildbot-2/fedora-x86-64-2/fedora-i686/build/gdb/testsuite/gdb.arch/i386-biarch-core.core "/home/gdb-buildbot-2/fedora-x86-64-2/fedora-i686/build/gdb/testsuite/gdb.arch/i386-biarch-core.core" is not a core dump: File format not recognized (gdb) FAIL: gdb.arch/i386-biarch-core.exp: core-file There are two problems: (1) The testcase did not really test if elf64-i386 is supported by GDB (BFD). That was OK for a Fedora testcase but I forgot about it when submitting it upstream. I haven't really verified if the GNU target is elf64-little but it seems so, no other one seems suitable from: elf32-x86-64 elf64-big elf64-k1om elf64-l1om elf64-little elf64-x86-64 pei-x86-64 (2) The output of the "core-file" command itself can be arbitrary as the elf64-i386 file with x86_64 registers is really broken; but that does not matter much, important is the following test whether core file memory is readable. ./configure --enable-64-bit-bfd (gdb) core-file /home/jkratoch/redhat/gdb-test-build32-plus64/gdb/testsuite/gdb.arch/i386-biarch-core.core^M warning: Couldn't find general-purpose registers in core file.^M Failed to read a valid object file image from memory.^M warning: Couldn't find general-purpose registers in core file.^M #0 <unavailable> in ?? ()^M (gdb) FAIL: gdb.arch/i386-biarch-core.exp: core-file x/i 0x400078^M 0x400078: hlt ^M (gdb) PASS: gdb.arch/i386-biarch-core.exp: .text is readable I do not know much dejagnu but I expect 'istarget' tests against the site.exp 'target_triplet' content which is set to the primary GDB target (--target=...). GDB is normally never configured for primary target elf64-i386, I think BFD does not know such explicit target, it gets recognized as elf64-little. In fact many testfiles of the GDB testsuite are wrong as they require 'istarget' (therefore primary GDB target) even for just loading arch specific files which would be sufficient with secondary target (--enable-targets=...) support. This my new patch removes this 'istarget' check as it is IMO unrelated to what we need to test. Although you are right we do 'x/i' and test for 'hlt' so I think we should test also for available 'set architecture i386'. We could also test by 'x/bx' instead of 'x/i' to avoid such additional test/requirement. This testcase comes from a different bug from 2009: https://bugzilla.redhat.com/show_bug.cgi?id=457187 http://pkgs.fedoraproject.org/cgit/gdb.git/commit/?id=94cd124608bf0dd359cb48a710800d72c21b30c3 That bug has been fixed in the meantime but the same testcase was reproducing this new different bug - internal error regression - so I submitted it. We can remove the "x/bx $address" test but it was useful for the previous bug from 2009 as that time the internal error regression did not happen, just the core file was not recognized (which would not be detected by the proposed ignoring of the "core-file" command output) and so the core file was not available. That can be tested by the "x/bx $address" test. gdb/testsuite/ChangeLog 2015-07-16 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.arch/i386-biarch-core.exp: Replace istarget by "complete set gnutarget".

Fix the ARI warning about the use of unsigned long long. We can't use ULONGEST as this is defined unsigned long on 64-bit systems. This will result in a compile error when storing a pointer to an unsigned long long structure field (declared in perf_event.h as __u64) in a ULONGEST * variable.

2015-07-14Remove CHECK_TYPEDEF, use check_typedef insteadSimon Marchi51-131/+179
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit annoying. It makes unclear the fact that the "type" variables gets overwritten. It has actually bitten me a few times. I think the following, explicit form, is better. type = check_typedef (type); This patches changes all instances of CHECK_TYPEDEF for an equivalent call to check_typedef. The bulk of the change was done with this sed: sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c The ChangeLog was generated using David Malcom's generate_changelog.py. I manually fixed those places where it gets the wrong function name, hopefully all of them.
