2013-08-23target.c:target_read_live_memory: Fix type of local.Pedro Alves2-1/+6
'ret' is used to hold the return of target_read, and pass it on. Both target_read and target_read_live_memory return LONGEST. gdb/ 2013-08-23 Pedro Alves <palves@redhat.com> * target.c (target_read_live_memory): Change type of 'ret' local to LONGEST.
2013-08-23remote.c: don't install a deprecated_xfer_memory hook.Pedro Alves2-66/+27
There's no need for deprecated_xfer_memory nowadays. Memory access goes through target_xfer_partial/TARGET_OBJECT_MEMORY, etc. In fact, the remote target already handles that, and is deferring to the same helpers the deprecated_xfer_memory hook is. Basically, only a few adjustments to make these helper routines's interfaces closer to target_xfer_partial's were necessary. Tested on x86_64 Fedora 17 w/ gdbserver. gdb/ 2013-08-23 Pedro Alves <palves@redhat.com> * remote.c (remote_write_bytes_aux, remote_write_bytes) (remote_read_bytes): Change return type to LONGEST, and adjust to return a target_xfer_error on error.

2013-08-22[Committing the `catch syscall' patch for ARM, from Samuel Bronson.]Sergio Durigan Junior6-4/+82
This time, it passes all the tests and comes with a nearly complete XML file (plus a script that can nearly regenerate the XML file). (I elected to leave out __ARM_NR_cmpxchg, since it has dire warnings to the effect that the only pieces of code that should be aware of it are the implementation and the __kuser_cmpxchg code in entry-armv.S.) gdb/ 2013-08-14 Samuel Bronson <naesten@gmail.com> ARM Linux support for `catch syscall'. * syscalls/arm-linux.py: New file. * syscalls/arm-linux.xml: Likewise. * arm-linux-tdep.c (arm_linux_get_syscall_number): New function.

2013-08-22fix dwz.exp on 32-bit targetsTom Tromey3-6/+54
This fixes dwz.exp on 32-bit targets. It does so by introducing a new "default" setting for the address size in the DWARF assembler. Built and regtested on x86-64 Fedora 18. I also ran the gdb.dwarf2 tests on an x86 machine (gcc45). * lib/dwarf.exp (cu, tu): Handle addr_size of "default". Change default addr_size. * lib/gdb.exp (is_64_target): New gdb_caching_proc.
2013-08-22convert one more caching procTom Tromey2-21/+22
I noticed that skip_btrace_tests is a classic "caching proc" that I missed when I added gdb_caching_proc. This patch converts it. Built and regtested on x86-64 Fedora 18. * lib/gdb.exp (skip_btrace_tests): Use gdb_caching_proc and standard_temp_file.
2013-08-22fix gdb.arch to be parallel-safeTom Tromey18-85/+53
This fixes parts of gdb.arch to be parallel-safe. I only changed the bits I could test on this machine. I don't have access to many of the machines needed to fully switch gdb.arch; but I am happy to provide advice to others attempting this. Or, I can send an untested patch to convert it all. Tested on x86-64 Fedora 18. * gdb.arch/amd64-byte.exp: Use standard_testfile, clean_restart. * gdb.arch/amd64-disp-step.exp: Use standard_testfile. * gdb.arch/amd64-dword.exp: Use standard_testfile, clean_restart. * gdb.arch/amd64-entry-value-param.exp: Use standard_testfile. * gdb.arch/amd64-entry-value.exp: Use standard_testfile. * gdb.arch/amd64-prologue-xmm.exp: Use standard_testfile. * gdb.arch/amd64-word.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-avx.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-byte.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-disp-step.exp: Use standard_testfile. * gdb.arch/i386-dr3-watch.exp: Use standard_testfile. * gdb.arch/i386-permbkpt.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-signal.exp: Use standard_testfile. * gdb.arch/i386-size-overlap.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-sse.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-unwind.exp: Use standard_testfile. * gdb.arch/i386-word.exp: Use standard_testfile, clean_restart.
2013-08-22fix gdb.python to be parallel-safeTom Tromey12-26/+62

2013-08-22use standard_temp_file in another caching procTom Tromey2-4/+8
In an earlier patch I forgot to change the caching proc in cell.exp to use standard_temp_file. This fixes the oversight. Tested on x86-64 Fedora 18. * lib/cell.exp (skip_cell_tests): Use standard_temp_file.
2013-08-22introduce gdb_remote_download and finish parallel fixes in gdb.dwarf2Tom Tromey8-6/+34
This finishes making gdb.dwarf2 parallel-safe. To do this, this patch introduces a new gdb_remote_download proc, that works somewhat differently in the one specific case where it matters: for a copy to "host", if no destination was given, and the host is not actually remote, then standard_output_file is used. In parallel mode this guarantees that the resulting file will end up in a parallel-safe location. Tested on x86-64 Fedora 18. * gdb.dwarf2/dw2-basic.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-compressed.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-intercu.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-intermix.exp: Use gdb_remote_download. * gdb.dwarf2/dw2-producer.exp: Use gdb_remote_download. * gdb.dwarf2/mac-fileno.exp: Use gdb_remote_download. * lib/gdb.exp (gdb_remote_download): New proc.
2013-08-22fix some gdb.dwarf2 tests for parallel safetyTom Tromey7-15/+39
This fixes a few gdb.dwarf2 tests to be more parallel-safe. This mostly amounts to changing them to write their files into the directory designated by standard_output_file. Built and regtested on x86-64 Fedora 18. * gdb.dwarf2/clztest.exp: Use standard_testfile. * gdb.dwarf2/dw2-minsym-in-cu.exp: Use standard_testfile. * gdb.dwarf2/fission-base.S: Remove directory from DW_AT_GNU_dwo_name. * gdb.dwarf2/fission-base.exp: Use build_executable. Set debug-file-directory. * gdb.dwarf2/fission-reread.S: Remove directory from DW_AT_GNU_dwo_name. * gdb.dwarf2/fission-reread.exp: Use build_executable. Set debug-file-directory.
2013-08-22PR gdb/15871: Unavailable entry value is not shown correctlyPedro Alves4-18/+105
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.

This fixes PR python/15816. The bug here is that python-selftest.exp can fail: No symbol "RETURN_MASK_ALL" in current context. RETURN_MASK_ALL is a macro, so if macros do not end up in the debuginfo (very typical) then the test fails. It seemed simplest to me to simply turn the RETURN_MASK_ defines into enum constants. This way they end up in the debuginfo and all is well. PR python/15816: * exceptions.h (return_mask): Now an enum. (RETURN_MASK_QUIT, RETURN_MASK_ERROR, RETURN_MASK_ALL): Now enum constants.

2013-08-20move gdbarch object from objfile to per-BFDTom Tromey10-21/+41
This moves the "gdbarch" field from the objfile into the BFD. This field's value is derived from the BFD and is immutable over the lifetime of the BFD. This makes it a reasonable candidate for pushing into the per-BFD object. This is part of the long-term objfile splitting project. In the long run I think this patch will make it simpler to moves types from the objfile to the per-BFD object; but the patch makes sense as a minor cleanup by itself.

2013-08-19linux-nat.c: no need to block child signals so aggressively.Pedro Alves2-45/+22
In http://sourceware.org/ml/gdb-patches/2013-08/msg00174.html , the issue of child signal handling around ptrace option support discovery being different between GDB and GDBserver came up. I recalled adding these block_child_signals calls, and the "We don't want those ptrace calls to be interrupted" comment, but not exactly why. So I looked into it. My first guess is that I got confused. The patch that added this <http://sourceware.org/ml/gdb-patches/2009-04/msg00125.html> rewrote the linux native async support completely, and the old async support code had the SIGCHLD handler itself do waitpid, so in places that we'd want a blocking waitpid, we'd have to have the signal handler blocked. That was probably the mindset I had at the time. Anyway, whatever the case, looks like I was wrong on the need for this blocking. Given GDBserver doesn't block like this, I investigated why this is currently needed on GDB but not on GDBserver. I removed the block_child_signals (and restore) calls, and hacked linux-nat.c to call linux_test_for_tracefork in a loop, like: @@ -534,7 +534,10 @@ static int linux_supports_tracefork (int pid) { if (linux_supports_tracefork_flag == -1) - linux_test_for_tracefork (pid); + { + while (1) + linux_test_for_tracefork (pid); + } return linux_supports_tracefork_flag; } Running the resulting GDB, I then saw bad things happening. Specifically, I'd end up with a bunch of zombies, and eventually, the machine would refuse to spawn new processes, claming insufficient resources. The issue is that linux_test_for_tracefork test forks, and has the child fork again. If we don't block SIGCHLD on entry to the function, the children will inherit SIGCHLD's action/disposition (meaning, SIGCHLD will be unblocked in the child). When the first child forks again a second child, and that child exits, the first child gets a SIGCHLD. Now, when we try to wrap up for the whole options test, we kill the first child, and collect the waitstatus. Here, when SIGCHLD isn't blocked, GDB will first see the child reporting a stop with SIGCHLD. gdbserver's ptrace options test does a PTRACE_KILL loop at the end, which catches the SIGCHLD, and retries the kill. The GDB version did not do that. So the GDB version would proceed, leaving the child zombie (until GDB exists), as nothing collected its final waitstatus. So this patch makes the GDB version of linux_test_for_tracefork do the exact same as the GDBserver version, removes all this unnecessary blocking throughout, and adds a couple comments at places that do need it -- namely: places where we'll use sleep with sigsuspend; and linux_async_pipe, as that destroys the pipe the signal handler touches. Tested on x86_64 Fedora 17, sync and async. gdb/ 2013-08-19 Pedro Alves <palves@redhat.com> * linux-nat.c (linux_test_for_tracefork) (linux_test_for_tracesysgood, linux_child_follow_fork) (lin_lwp_attach_lwp, linux_nat_resume): Don't block child signals.

2013-08-14move some static thread state into remote_stateTom Tromey2-19/+31
This moves a few static variables from thread-info functions into remote_state. Pedro said on irc that these functions implement the ancient thread-discovery method and that he wouldn't be surprised if they had rotted; nevertheless it seems safer to me to make them explicitly per-remote. This necessitated moving a couple of macros and a typedef earlier in the file. * remote.c (struct remote_state) <echo_nextthread, nextthread, resultthreadlist>: New fields. (OPAQUETHREADBYTES, threadref, MAXTHREADLISTRESULTS): Move earlier. (remote_get_threadlist, remote_threadlist_iterator): Use new fields. Remove static variables.

2013-08-14move sizeof_pkt into remote_trace_findTom Tromey2-3/+6
The global sizeof_pkt is only used in remote_trace_find, like so: reply = remote_get_noisy_reply (&(rs->buf), &sizeof_pkt); I think in this situation it is more correct to use the recorded size of the buffer. Otherwise it seems that some skew could result. * remote.c (sizeof_pkt): Remove. (remote_trace_find): Use rs->buf_size, not sizeof_pkt.

gdb has a copy of some CRC code that also appears in libiberty. This patch just removes the local copy. You may notice that "crc32" returns unsigned long but "xcrc32" returns unsigned int. However, this does not matter, because crc32 actually does all its operations in unsigned int type, and only the return result is widened. So, the difference does not matter. * remote.c (crc32_table, crc32): Remove. (remote_verify_memory): Use xcrc32.
