2015-06-24Call set_gdbarch_get_siginfo_type in linux_init_abiYao Qi1-2/+0
linux_get_siginfo_type is installed to many linux gdbarch. This patch is to move this to a common area linux-tdep.c:linux_init_abi, so that linux_get_siginfo_type is installed to every linux gdbarch. If some linux gdbarch needs its own version, please override it in $ARCH_linux_init_abi. In the testsuite, we enable siginfo related tests for all linux targets. gdb: 2015-06-24 Yao Qi <yao.qi@linaro.org> * aarch64-linux-tdep.c (aarch64_linux_init_abi): Don't call set_gdbarch_get_siginfo_type. * amd64-linux-tdep.c (amd64_linux_init_abi_common): Likewise. * arm-linux-tdep.c (arm_linux_init_abi): Likewise. * i386-linux-tdep.c (i386_linux_init_abi): Likewise. * m68klinux-tdep.c (m68k_linux_init_abi): Likewise. * ppc-linux-tdep.c (ppc_linux_init_abi): Likewise. * s390-linux-tdep.c (s390_gdbarch_init): Likewise. * tilegx-linux-tdep.c (tilegx_linux_init_abi): Likewise. * linux-tdep.c (linux_get_siginfo_type): Change it to static.

2015-04-10PR13858 - Can't do displaced stepping with no symbolsPedro Alves1-0/+5
Running break-interp.exp with the target always in non-stop mode trips on PR13858, as enabling non-stop also enables displaced stepping. The problem is that when GDB doesn't know where the entry point is, it doesn't know where to put the displaced stepping scratch pad. The test added by this commit exercises this. Without the fix, we get: (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: break *$pc set displaced-stepping on (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: set displaced-stepping on stepi 0x00000000004005be in ?? () Entry point address is not known. (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: stepi p /x $pc $2 = 0x4005be (gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: get after PC FAIL: gdb.base/step-over-no-symbols.exp: displaced=on: advanced The fix switches all GNU/Linux ports to get the entry point from AT_ENTRY in the target auxiliary vector instead of from symbols. This is currently only done by PPC when Cell debugging is enabled, but I think all archs should be able to do the same. Note that ppc_linux_displaced_step_location cached the result, I'm guessing to avoid constantly re-fetching the auxv out of remote targets, but that's no longer necessary nowadays, as the auxv blob is itself cached in the inferior object. The ppc_linux_entry_point_addr global is obviously bad for multi-process too nowadays. Tested on x86-64 (-m64/-m32), PPC64 (-m64/-m32) and S/390 GNU/Linux.

2013-08-09This patch implements the new gdbarch method gdbarch_gdb_signal_to_target.Sergio Durigan Junior1-0/+6
It will be used when one wants to convert between the internal GDB signal representation (enum gdb_signal) and the target's representation. The idea of this patch came from a chat between Pedro and I on IRC, plus the discussion of my patches to add the new $_exitsignal convenience variable: <http://sourceware.org/ml/gdb-patches/2013-06/msg00452.html> <http://sourceware.org/ml/gdb-patches/2013-06/msg00352.html> What I did was to investigate, on the Linux kernel, which targets shared the signal numbers definition with the generic definition, present at <include/uapi/asm-generic/signal.h>. For the record, I used linux-3.10-rc7 as the main source of information, always looking at <arch/<ARCH_NAME>/include/uapi/asm/signal.h>. For SIGRTMAX (which defaults to _NSIG in most cases), I had to look at different signal-related files, but most of them (except MIPS) were defined to 64 anyway. Then, with all the differences in hand, I implemented the bits on each target. 2013-08-09 Sergio Durigan Junior <sergiodj@redhat.com> * linux-tdep.c: Define enum with generic signal numbers.

Two modifications: 1. The addition of 2013 to the copyright year range for every file; 2. The use of a single year range, instead of potentially multiple year ranges, as approved by the FSF.
