2010-03-18[dwarf] Anonymous nested function causes SEGV during psymbol readJoel Brobecker5-5/+335
According to the DWARF3 standard, a function always has a name attribute (Section 3.3 - Subroutine and Entry Point Entries). The only exception is when a DW_AT_abstract_origin attribute is provided, in which case the name may be inherited from the referenced DIE. The problem occured because our compiler generated a subprogram DIE for a nested function where the name attribute was missing (and no abstract-origin either). Our code in add_partial_symbol is not prepared to deal with the situation, and happily just tries to compute the length of the (NULL) function name. This normally cannot happen, because there is already a guard in scan_partial_symbols, where we (silently!) ignore anonymous dies, including anonymous subprograms. Unfortunately, there is a flaw that affects Ada and other languages that allow nested subprograms. For nested subprograms, we do not go through scan_partial_symbols and thus we are missing the name check. This patch adds the name check in the nested subprogram case. It also adds a complaint which is emitted during the psymtab->symtab conversion phase. gdb/ChangeLog: * dwarf2read.c (add_partial_subprogram): Make sure the subprogram DIE has a name before creating the associated partial symbol. (read_func_scope): Emit a complaint if the subprogram does not have a name or when we can't extract the subprogram PC bounds. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-anonymous-func.S: New file. * gdb.dwarf2/dw2-anonymous-func.exp: New testcase. Tested on x86_64-linux, no regression. Note that the testcase also verifies that the psymtab->symtab conversion does not crash (this is the purpose of the "list file1.txt:1" test.

The common code sets up an autoconf option --enable-sim-trace which adds -DTRACE= to CPPFLAGS. This causes warnings in the building of some files that declare a local TRACE() helper macro. So punt it from hw-ports.c (since it isn't actually used) and convert hw-properties.c to HW_TRACE().

2010-03-16Avoid switch to invalid ptid during Ada task switch.Joel Brobecker2-0/+18
This is to prevent an internal error during an Ada task switch. A task switch is simply a thread switch under the hood. What we do is collect the info from the Ada Task Control Block, deduce the associated thread ptid, and then switch to that thread. If the thread ptid computation routine has not been implemented for the target, of if there is a bug, then we end up computing a bogus ptid which GDB does not know about, which eventually leads to an assertion failure: (gdb) task 1 [New Thread 5715] /[...]/gdb/thread.c:595: internal-error: is_thread_state: Assertion `tp' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) When this happens, it's just nicer for the user to print an error message, and cancel the task switch. After this patch is applied, this is what we get: (gdb) task 1 [New Thread 10250] Unable to compute thread ID for task 1. Cannot switch to this task. gdb/ChangeLog: * ada-tasks.c (task_command_1): Check that the task ptid is valid before doing the associated thread switch.
