2014-05-20[GDBserver][AArch64] Make watchpoint support use target_hw_bp_type.Pedro Alves2-39/+82
This makes linux-aarch64-low.c use target_hw_bp_type, like gdb's aarch64-linux-nat.c. The original motivation is decoupling insert_point/remove_point from Z packet numbers, but I think making the files a little bit more similar is a good thing on its own right. Ideally we'd merge these files even... The aarch64_point_encode_ctrl_reg change is taken straight from GDB's copy. I confirmed with a cross compiler that this builds, but it's otherwise untested. gdb/gdbserver/ 2014-05-20 Pedro Alves <palves@redhat.com> * linux-aarch64-low.c: Include break-common.h. (enum target_point_type): Delete. (Z_packet_to_point_type): Rename to ... (Z_packet_to_target_hw_bp_type): ... this, and return a target_hw_bp_type instead. (aarch64_show_debug_reg_state): Take an enum target_hw_bp_type instead of an enum target_point_type. (aarch64_point_encode_ctrl_reg): Likewise. Compute type mask from breakpoint type.

(aarch64_supports_z_point_type): New function. (aarch64_insert_point, aarch64_remove_point): Use it. Adjust to use Z_packet_to_target_hw_bp_type.
2014-05-20Do not build gdbserver with -Werror by default if development=falseJoel Brobecker3-4/+10
On GDB release branches, we change $development in gdb/development.sh to false, in order to build the GDB release without -Werror by default, thus avoiding harmless compiler warnings from breaking the build of someone who's only interested in building GDB rather than working on it. This patch implements the same strategy for gdbserver, using the exact same method. gdb/gdbserver/ChangeLog: * configure.ac: Only use -Werror by default when DEVELOPMENT is true. * configure: Regenerate. Tested on x86_64-linux, by rebuilding GDBserver first with development set to true, and then doing it again with development set to false. Werror was used in the first case, but not in the second.
2014-05-20btrace: no replay without historyMarkus Metzger4-0/+58
When using a reverse execution command without execution history, GDB might end up in a state where replaying has been started but remains at the current instruction. This state is illegal.

2014-05-20Set timeout for gdb.reverse/*.exp test casesYao Qi3-0/+21
Hi, This patch is to add a new board setting gdb_reverse_timeout, which is used to set timeout for all gdb.reverse test cases, which are usually very slow and cause some TIMEOUT failures, for example, on some arm boards. We have some alternatives to this approach, but I am not satisfied with them: - Increase the timeout value. This is the global change, and it may cause some delay where actual failures happen. - Set timeout by gdb_reverse_timeout in every gdb.reverse/*.exp. Then, we have to touch every file under gdb.reverse. In this patch, we choose a central place to set timeout for all tests in gdb.reverse, which is convenient. gdb/testsuite: 2014-05-20 Yao Qi <yao@codesourcery.com> * lib/gdb.exp (gdb_init): Set timeout if test file is under gdb.reverse directory and gdb_reverse_timeout exists in board setting. * README: Document gdb_reverse_timeout.
2014-05-20gdb_init argument ARGS is a string rather than a listYao Qi2-10/+12
The argument ARGS of gdb_init is passed from dejagnu is a string, the test file name. In dejagnu/runtest.exp: proc runtest { test_file_name } { .... .... if [info exists tool] { if { [info procs "${tool}_init"] != "" } { ${tool}_init $test_file_name; } } .... } but inn default_gdb_init (callee of gdb_init), we have set gdb_test_file_name [file rootname [file tail [lindex $args 0]]] In tcl, all actual arguments are combined to a list and assigned to args. This code here isn't wrong, but unnecessary, because its caller (proc runtest) only passes one string to it, and IMO, we don't need such tricky tcl "args". I doubt that "[lindex $args 0]" is to be backward compatible with old dejagnu, but dejagnu-1.4 release started to pass $test_file_name to ${too}_init, as I showed above. dejagnu-1.4 was released in 2001, and it should be old enough. I also tried to check whether gdb testusite works with dejagnu-1.3 or not, but failed to build dejagnu-1.3 on my machine. Supposing GDB testsuite requires at least dejagnu-1.4, this change should be safe. This patch is update default_gdb_init to treat ARGS as a string instead of a list. Then, 'args' sounds like a list, and this patch also renames it by 'test_file_name', to align with dejagnu. gdb/testsuite: 2014-05-20 Yao Qi <yao@codesourcery.com> * lib/gdb.exp (default_gdb_init): Rename argument 'args' by 'test_file_name'. Treat args as a string instead of a list. (gdb_init): Rename argument 'args' by 'test_file_name'.
2014-05-20Fix issue #15778: GDB Aarch64 signal frame unwinder issueHui Zhu2-29/+41
The root cause of this issue is unwinder of "#3 <signal handler called>" doesn't supply right values of registers. When GDB want to get the previous frame of "#3 <signal handler called>", it will call cache init function of unwinder "aarch64_linux_sigframe_init". The address or the value of the registers is get from this function. So the bug is inside thie function. I check the asm code of "#3 <signal handler called>": (gdb) frame 3 (gdb) p $pc $1 = (void (*)()) 0x7f931fa4d0 (gdb) disassemble $pc, +10 Dump of assembler code from 0x7f931fa4d0 to 0x7f931fa4da: => 0x0000007f931fa4d0: mov x8, #0x8b // #139 0x0000007f931fa4d4: svc #0x0 0x0000007f931fa4d8: nop This is the syscall sys_rt_sigreturn, Linux kernel function "restore_sigframe" will set the frame: for (i = 0; i < 31; i++) __get_user_error(regs->regs[i], &sf->uc.uc_mcontext.regs[i], err); __get_user_error(regs->sp, &sf->uc.uc_mcontext.sp, err); __get_user_error(regs->pc, &sf->uc.uc_mcontext.pc, err); The struct of uc_mcontext is: struct sigcontext { __u64 fault_address; /* AArch64 registers */ __u64 regs[31]; __u64 sp; __u64 pc; __u64 pstate; /* 4K reserved for FP/SIMD state and future expansion */ __u8 __reserved[4096] __attribute__((__aligned__(16))); }; But in GDB function "aarch64_linux_sigframe_init", the code the get address of registers is: for (i = 0; i < 31; i++) { trad_frame_set_reg_addr (this_cache, AARCH64_X0_REGNUM + i, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + i * AARCH64_SIGCONTEXT_REG_SIZE); } trad_frame_set_reg_addr (this_cache, AARCH64_FP_REGNUM, fp); trad_frame_set_reg_addr (this_cache, AARCH64_LR_REGNUM, fp + 8); trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, fp + 8); The code that get pc and sp is not right, so I change the code according to Linux kernel code: trad_frame_set_reg_addr (this_cache, AARCH64_SP_REGNUM, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + 31 * AARCH64_SIGCONTEXT_REG_SIZE); trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + 32 * AARCH64_SIGCONTEXT_REG_SIZE); The issue was fixed by this change, and I did the regression test. It also fixed a lot of other XFAIL and FAIL. 2014-05-20 Hui Zhu <hui@codesourcery.com> Yao Qi <yao@codesourcery.com> PR backtrace/16558 * aarch64-linux-tdep.c (aarch64_linux_sigframe_init): Update comments and change address of sp and pc.

2014-05-20Rewrite ppc32 backend .sdata and .sdata2 handlingAlan Modra7-118/+150
1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar manner to the way _GLOBAL_OFFSET_TABLE_ is handled. It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections.

2014-05-19fix two latent type errorsTom Tromey3-4/+7
I'm checking this in as obvious. I was looking at instances of "alloc.*sizeof" and noticed a couple where the types in question are incorrect. In gdbtypes, the code allocates sizeof(int) to represent a struct rank. In mi-cmds, the code uses "struct mi_cmd **" -- one "*" too many. In both cases the problems are latent because in practice the sizes are the same as the sizes of the correct types. Still, it's better to be correct. I think gdb would be improved by a wholesale change from explicit sizeofs to using the libiberty.h allocation macros. In most cases they are both shorter and have better type safety. However, the resulting patch is rather large.

2014-05-15Make more robust when run in parallel mode.Doug Evans3-3/+18
Since we're not compiling with gcc, we don't know where the DWO file will ultimately be built. It could be built in testsuite/gdb.dwarf2/foo (non-parallel mode) or testsuite/outputs/gdb.dwarf2/foo (parallel mode). * gdb.dwarf2/fission-reread.S: Remove directory from .dwo file path. * gdb.dwarf2/fission-reread.exp: Set debug-file-directory before loading file. Add test for TU lookup.

2014-05-15Fix argument passing in mi_run_cmd_fullSimon Marchi2-1/+18
Passing arguments did not work when use_mi_command was set. gdb/testsuite/ChangeLog: 2014-05-13 Simon Marchi <simon.marchi@ericsson.com> * lib/mi-support.exp (mi_run_cmd_full): Set arguments by calling "-exec-arguments" or "set args" before running the inferior.
2014-05-15Fix mi_expect_stop for non-zero exit codesSimon Marchi2-0/+19
The message displayed by gdb is different when the inferior exits with zero and non-zero values, this fix takes that into account. gdb/testsuite/ChangeLog: 2014-05-13 Simon Marchi <simon.marchi@ericsson.com> * lib/mi-support.exp (mi_expect_stop): Expect message for inferiors that exit with non-zero exit code.
2014-05-15Fix "overflow in PLT unwind data" warningAlan Modra2-33/+52
When linking statically, it's possible to hit this warning with IFUNC or very large executables, due to .glink being unused. * powerpc.cc (do_plt_fde_location): Handle zero length .glink. Compare FDE contents with DW_CFA_nop rather than 0.

I happened to notice that print_macro_definition is indented improperly. All the lines were a few extra spaces to the right. This patch fixes the indentation. Tested by rebuilding, committed. 2014-05-14 Tom Tromey <tromey@redhat.com> * macrocmd.c (print_macro_definition): Reindent.
