2014-07-24Remove some GDBSERVER checks from linux-ptraceTom Tromey4-25/+52
This patch removes some GDBSERVER checks from nat/linux-ptrace.c. Currently the code uses a compile-time check to decide whether some flags should be used. This changes the code to instead let users of the module specify an additional set of flags; and then changes gdb's linux-nat.c to call this function. At some later date, when the back ends are fully merged, we will be able to remove this function again. gdb/ 2014-07-24 Tom Tromey <tromey@redhat.com> Gary Benson <gbenson@redhat.com> * nat/linux-ptrace.c (additional_flags): New global.

2014-07-24auto-generate most target debug methodsTom Tromey6-700/+2589
The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

2014-07-24Rationalize "fatal" error handling outside of gdbserverGary Benson5-33/+35
GDB and gdbserver have functions named "fatal" that are used in completely different ways. In gdbserver "fatal" is used to handle critical errors: it differs from "error" in that "fatal" causes gdbserver to exit whereas "error" does not. In GDB "fatal" is used to abort the current operation and return to the command level. This is implemented by throwing a non-error "RETURN_QUIT" exception. This commit removes GDB's "fatal" and "vfatal" functions entirely. The exception-throwing function "throw_vfatal" is renamed as "throw_vquit", and a new convenience function "throw_quit" is added. The small number of calls to "fatal" are replaced with calls to "throw_quit", making what is happening more obvious. This commit also modifies GDB's "throw_error" to call "throw_verror" rather than calling "throw_it" directly. This change means the assignment of RETURN_ERROR as the exception type now happens in precisely one place in GDB rather than two. gdb/ 2014-07-24 Gary Benson <gbenson@redhat.com> * exceptions.h (throw_vfatal): Renamed to... (throw_vquit): New declaration. (throw_quit): Likewise. * exceptions.c (throw_vfatal): Renamed to... (throw_vquit): New function. (throw_quit): Likewise. (throw_error): Call throw_verror rather than throw_it. * utils.h (vfatal): Removed. (fatal): Likewise. * utils.c (vfatal): Removed. (fatal): Likewise. (internal_verror): Replaced call to fatal with call to throw_quit. (quit): Replaced calls to fatal with calls to throw_quit.

2014-07-23rewrite make-target-delegates matching codeTom Tromey3-55/+83
This patch rewrites the make-target-delegates matching code a little bit. The result is functionally the same (the output has some small whitespace differences), but the new code is more forgiving regarding the formatting of target.h. In particular now there's no need to ensure that the return type and the method name appear on the same line. 2014-07-23 Tom Tromey <tromey@redhat.com> * make-target-delegates ($ARGS_PART): Match trailing close paren.

2014-07-22Remove setting value address for reference entry value target data value.Jan Kratochvil2-9/+5
I cannot reproduce any wrong case having the code removed. I just do not find it correct to have it disabled. But at the same time I do like much / I do not find correct the code myself. It is a bit problematic to have struct value describing a memory content which is no longer present there. What happens there: ------------------------------------------------------------------------------ volatile int vv; static __attribute__((noinline)) int bar (int &ref) { ref = 20; vv++; /* break-here */ return ref; } int main (void) { int var = 10; return bar (var); } ------------------------------------------------------------------------------ <4><c7>: Abbrev Number: 13 (DW_TAG_GNU_call_site_parameter) <c8> DW_AT_location : 1 byte block: 55 (DW_OP_reg5 (rdi)) <ca> DW_AT_GNU_call_site_value: 2 byte block: 91 74 (DW_OP_fbreg: -12) <cd> DW_AT_GNU_call_site_data_value: 1 byte block: 3a (DW_OP_lit10) ------------------------------------------------------------------------------ gdb -ex 'b value_addr' -ex r --args ../gdb ./1 -ex 'watch vv' -ex r -ex 'p &ref@entry' -> 6 return ref; bar (ref=@0x7fffffffd944: 20, ref@entry=@0x7fffffffd944: 10) at 1.C:25 ------------------------------------------------------------------------------ At /* break-here */ struct value variable 'ref' is TYPE_CODE_REF. With FSF GDB HEAD: (gdb) x/gx arg1.contents 0x6004000a4ad0: 0x00007fffffffd944 (gdb) p ((struct value *)arg1.location.computed.closure).lval $1 = lval_memory (gdb) p/x ((struct value *)arg1.location.computed.closure).location.address $3 = 0x7fffffffd944 With your #if0-ed code: (gdb) x/gx arg1.contents 0x6004000a4ad0: 0x00007fffffffd944 (gdb) p ((struct value *)arg1.location.computed.closure).lval $8 = not_lval (gdb) p/x ((struct value *)arg1.location.computed.closure).location.address $9 = 0x0 I do not see how to access ((struct value *)arg1.location.computed.closure).location.address from GDB CLI. Trying (gdb) p &ref@entry will invoke value_addr()'s: if (TYPE_CODE (type) == TYPE_CODE_REF) /* Copy the value, but change the type from (T&) to (T*). We keep the same location information, which is efficient, and allows &(&X) to get the location containing the reference. */ and therefore the address gets fetched already from arg1.contents and not from ((struct value *)arg1.location.computed.closure).location.address . And for any other type than TYPE_CODE_REF this code you removed does not get executed at all. This DW_AT_GNU_call_site_data_value DWARF was meant primarily for Fortran but with -O0 entry values do not get produced and with -Og and higher Fortran always optimizes out the passing by reference. If you do not like the removed code there I am OK with removing it as I do not know how to make it's use reproducible for user anyway. In the worst case - if there really is some way how to exploit it - one should just get Attempt to take address of value not located in memory. instead of some wrong value and it may be easy to fix then. gdb/ 2014-07-22 Jan Kratochvil <jan.kratochvil@redhat.com> * dwarf2loc.c (value_of_dwarf_reg_entry): Remove setting value address for reference entry value target data value.

While working on some target stack changes, I noticed that exec_ops is only used from exec.c. This patch makes it "static". This is cleaner and makes it simpler to reason about the use of the target.

2014-07-18fix calls to find_target_beneathTom Tromey3-3/+11
A long time ago Pedro pointed out that there are some calls to find_target_beneath that pass in an explicit target_ops; but which should instead use the ops provided to the method in question. See: https://sourceware.org/ml/gdb-patches/2014-01/msg00429.html This patch is just a minor cleanup to fix all such calls. There were only three. 2014-07-18 Tom Tromey <tromey@redhat.com> * spu-multiarch.c (spu_region_ok_for_hw_watchpoint): Pass "self" to find_target_beneath. * ravenscar-thread.c (ravenscar_prepare_to_store): Pass "ops" to find_target_beneath.

2014-07-18fix PR gdb/17130Tom Tromey4-2/+34
This fixes PR gdb/17130. The bug is that some code in utils.c was not updated during the target delegation change: if (job_control /* If there is no terminal switching for this target, then we can't possibly get screwed by the lack of job control. */ || current_target.to_terminal_ours == NULL) fatal ("Quit"); else fatal ("Quit (expect signal SIGINT when the program is resumed)"); After the delegation change, to_terminal_ours will never be NULL. I think this bug can be seen before the target delegation change by enabling target debugging -- this would also cause to_terminal_ours to be non-NULL. The fix is to introduce a new target_supports_terminal_ours function, that properly checks the target stack. This is not perhaps ideal, but I think is a reasonable-enough approach, and in keeping with some other existing code of the same form. This patch also fixes a similar bug in target_supports_delete_record. 2014-07-18 Tom Tromey <tromey@redhat.com> PR gdb/17130: * utils.c (quit): Use target_supports_terminal_ours. * target.h (target_supports_terminal_ours): Declare. * target.c (target_supports_delete_record): Don't check to_delete_record against NULL.

2014-07-18clean up some target delegation casesTom Tromey8-97/+50
This patch cleans up some minor inconsistencies in target delegation. It's primary purpose is to avoid confusion in the code. A few spots were checking the "beneath" target; however this can only be NULL for the dummy target, so such tests are not needed. Some other spots were iterating over the beneath targets, looking for a method implementation. This is not needed for methods handled by make-target-delegates, as there is always an implementation. 2014-07-18 Tom Tromey <tromey@redhat.com> PR gdb/17130: * spu-multiarch.c (spu_region_ok_for_hw_watchpoint) (spu_fetch_registers, spu_store_registers, spu_xfer_partial) (spu_search_memory, spu_mourn_inferior): Simplify delegation. * linux-thread-db.c (thread_db_pid_to_str): Always delegate. * windows-nat.c (windows_xfer_partial): Always delegate. * record-btrace.c (record_btrace_xfer_partial): Simplify delegation.

2014-07-18move exec_make_note_section earlierTom Tromey2-7/+9
This patch moves exec_make_note_section a bit earlier in exec.c. This lets us remove an otherwise unnecessary forward declaration and it also makes the file a bit more in line with other code, as now _initialize_exec is the final function in the file. Tested by rebuilding. I'm committing this as obvious. 2014-07-18 Tom Tromey <tromey@redhat.com> * exec.c (exec_make_note_section): Move earlier.
