2015-07-22Fix ppc64 ELFv1 assertion failureAlan Modra2-7/+11
Bogus assembly can hit an assertion in opd_entry_value when the symbol referenced by a function descriptor is undefined. Worse, the code after the assert copies unitialised memory to return the code section. This uninitialised pointer can later be dereferencd, possibly causing a linker segmentation fault. * elf64-ppc.c (opd_entry_value): Remove assertion. Instead, return -1 if symbol referenced is not defined. Tidy.

2015-07-20gdb.ada/info_exc.exp: Adjust expected output in "info exception" test.Joel Brobecker2-3/+5
Since multi_line was moved to gdb.exp in a slightly stricter form, The gdb.ada/info_exc.exp:info exceptions test has been failing. This is because it now expects a new-line sequence at the end of each argument given to multi_line, including ".*". But the intent when writing the test was to signify "could-be-nothing-at-all". As a result, the test fails on x86_64-linux with a runtime built as recommended, because of that extra new-line sequence. gdb/testsuite/ChangeLog: * gdb.ada/info_exc.exp: Adjust "info exceptions" expected output.

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.

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". Remove expectation for the "core-file" command.

2015-07-16[AArch64] Mark single precision pseudo registers unavailable if invalidPierre Langlois2-1/+10
I noticed two failure in gdb.trace/mi-trace-frame-collected.exp: FAIL: gdb.trace/mi-trace-frame-collected.exp: live: -trace-frame-collected (register) FAIL: gdb.trace/mi-trace-frame-collected.exp: tfile: -trace-frame-collected (register) In these cases, we are not collecting registers so the MI command -trace-frame-collected should only give us the value of the PC. However, it also gives us all of the single precision pseudo registers, initialized with 0x0. We can reproduce this error by simply issuing the 'maint print cooked-register' when no inferior is connected: ~~~ ... (gdb) maint print cooked-register Name Nr Rel Offset Size Type Cooked value x0 0 0 0 8 long <unavailable> x1 1 1 8 8 long <unavailable> ... d30 130 62 1540 8 *1 <unavailable> d31 131 63 1548 8 *1 <unavailable> s0 132 64 1556 4 *1 0x00000000 s1 133 65 1560 4 *1 0x00000000 s2 134 66 1564 4 *1 0x00000000 ... s28 160 92 1668 4 *1 0x00000000 s29 161 93 1672 4 *1 0x00000000 s30 162 94 1676 4 *1 0x00000000 s31 163 95 1680 4 *1 0x00000000 h0 164 96 1684 2 *1 <unavailable> h1 165 97 1686 2 *1 <unavailable> h2 166 98 1688 2 *1 <unavailable> ... ~~~ It turns out GDB does not check if S registers are valid before returning a value for them. It should return <unavailable> in this case. gdb/ChangeLog: * aarch64-tdep.c (aarch64_pseudo_read_value): Mark S register as unavailable if invalid.
