2013-08-22PR gdb/15871: Unavailable entry value is not shown correctlyPedro Alves1-1/+30
In entry-values.exp, we have a test where the entry value of 'j' is unavailable, so it is expected that printing j@entry yields "<unavailable>". However, the actual output is: (gdb) frame #0 0x0000000000400540 in foo (i=0, i@entry=2, j=2, j@entry=<error reading variable: Cannot access memory at address 0x6009e8>) The error is thrown here: #0 throw_it (reason=RETURN_ERROR, error=MEMORY_ERROR, fmt=0x8cd550 "Cannot access memory at address %s", ap=0x7fffffffc8e8) at ../../src/gdb/exceptions.c:373 #1 0x00000000005e2f9c in throw_error (error=MEMORY_ERROR, fmt=0x8cd550 "Cannot access memory at address %s") at ../../src/gdb/exceptions.c:422 #2 0x0000000000673a5f in memory_error (status=5, memaddr=6293992) at ../../src/gdb/corefile.c:204 #3 0x0000000000673aea in read_memory (memaddr=6293992, myaddr=0x7fffffffca60 "\200\316\377\377\377\177", len=4) at ../../src/gdb/corefile.c:223 #4 0x00000000006784d1 in dwarf_expr_read_mem (baton=0x7fffffffcd50, buf=0x7fffffffca60 "\200\316\377\377\377\177", addr=6293992, len=4) at ../../src/gdb/dwarf2loc.c:334 #5 0x000000000067645e in execute_stack_op (ctx=0x1409480, op_ptr=0x7fffffffce87 "\237<\005@", op_end=0x7fffffffce88 "<\005@") at ../../src/gdb/dwarf2expr.c:1045 #6 0x0000000000674e29 in dwarf_expr_eval (ctx=0x1409480, addr=0x7fffffffce80 "\003\350\t`", len=8) at ../../src/gdb/dwarf2expr.c:364 #7 0x000000000067c5b2 in dwarf2_evaluate_loc_desc_full (type=0x10876d0, frame=0xd8ecc0, data=0x7fffffffce80 "\003\350\t`", size=8, per_cu=0xf24c40, byte_offset=0) at ../../src/gdb/dwarf2loc.c:2236 #8 0x000000000067cc65 in dwarf2_evaluate_loc_desc (type=0x10876d0, frame=0xd8ecc0, data=0x7fffffffce80 "\003\350\t`", size=8, per_cu=0xf24c40) at ../../src/gdb/dwarf2loc.c:2407 #9 0x000000000067a5d4 in dwarf_entry_parameter_to_value (parameter=0x13a7960, deref_size=18446744073709551615, type=0x10876d0, caller_frame=0xd8ecc0, per_cu=0xf24c40) at ../../src/gdb/dwarf2loc.c:1160 #10 0x000000000067a962 in value_of_dwarf_reg_entry (type=0x10876d0, frame=0xd8de70, kind=CALL_SITE_PARAMETER_DWARF_REG, kind_u=...) at ../../src/gdb/dwarf2loc.c:1310 #11 0x000000000067aaca in value_of_dwarf_block_entry (type=0x10876d0, frame=0xd8de70, block=0xf1c2d4 "Q", block_len=1) at ../../src/gdb/dwarf2loc.c:1363 #12 0x000000000067e7c9 in locexpr_read_variable_at_entry (symbol=0x13a7540, frame=0xd8de70) at ../../src/gdb/dwarf2loc.c:3326 #13 0x00000000005daab6 in read_frame_arg (sym=0x13a7540, frame=0xd8de70, argp=0x7fffffffd0e0, entryargp=0x7fffffffd100) at ../../src/gdb/stack.c:362 #14 0x00000000005db384 in print_frame_args (func=0x13a7470, frame=0xd8de70, num=-1, stream=0xea3890) at ../../src/gdb/stack.c:669 #15 0x00000000005dc338 in print_frame (frame=0xd8de70, print_level=1, print_what=SRC_AND_LOC, print_args=1, sal=...) at ../../src/gdb/stack.c:1199 #16 0x00000000005db8ee in print_frame_info (frame=0xd8de70, print_level=1, print_what=SRC_AND_LOC, print_args=1) at ../../src/gdb/stack.c:851 #17 0x00000000005da2bb in print_stack_frame (frame=0xd8de70, print_level=1, print_what=SRC_AND_LOC) at ../../src/gdb/stack.c:169 #18 0x00000000005de236 in frame_command (level_exp=0x0, from_tty=1) at ../../src/gdb/stack.c:2265 dwarf2_evaluate_loc_desc_full (frame #7) knows to handle NOT_AVAILABLE_ERROR errors, but read_memory always throws a generic error. Presently, only the value machinery knows to handle unavailable memory. We need to push the awareness down to the target_xfer layer, making it return a finer grained error indication. We can only return a generic -1 nowadays, which leaves the upper layers with no clue on why the xfer failed. Use target_xfer_partial directly, rather than propagating the error through target_read_memory so as to get a better address to display in the error message. (target_read_memory & friends build on top of target_read (thus the target_xfer machinery), but turn all errors to EIO, an errno value. I think this is a mistake, and we'd better convert all these to return a target_xfer_error too, but that can be done separately. I looked around a bit over memory_error calls, and the need to handle random errno values, other than the EIOs gdb itself hardcodes, probably comes (only) from deprecated_xfer_memory, which uses errno for error indication, but I didn't look exhaustively. We should really get rid of deprecated_xfer_memory and of passing down errno values as error indication in target_read & friends methods). Tested on x86_64 Fedora 17, native and gdbserver.

2013-07-25remove pop_targetTom Tromey1-5/+1
This patch fixes the target double-close problem (PR remote/15266), and in the process removes pop_target entire (PR remote/15256). The first issue is that pop_target calls target_close. However, it then calls unpush_target, which also calls target_close. This means targets must be able to be closed twice. Not only is this strange, but it also directly contradicts the contract of to_xclose targets. (We currently have just a single such target, and it is never pushed; but I plan to add more, and so this latent bug is triggered.) The second issue is that it seems to me that calling pop_target is often unsafe. This is what cropped up in 15256, where the remote target assumed that it could pop_target -- but there was another target higher on the stack, leading to confusion. But, it is always just as easy to call unpush_target as it is to call pop_target; and it is also safer. So, removing pop_target seemed like an improvement. Finally, this adds an assertion to target_close to ensure that no currently-pushed target can be closed. Built and regtested on x86-64 Fedora 18; both natively and using the native-gdbserver board file.

2013-07-25don't call add_target for thread_db_opsTom Tromey1-0/+5
Right now, "help target" will include this line: target multi-thread -- Threads and pthreads support However, it doesn't make sense to invoke "target multi-thread". This patch fixes the problem by not registering the multi-thread target. add_target does some needed initialization of the target_ops, so I broke this out into a new function. It isn't clear to me whether this patch requires a test case or not. I'm not sure whether there are other unregistered targets; but if there are, it seems unlikely that we test for their absence from the help.
