errors evaluating the object before attempting to set its
value.
value_cast now properly adjusts VALUE_ADDRESS for baseclasses,
so this offset adjustment is no longer necessary.
(create_child): Don't set the error flag if the child is
a CPLUS_FAKE_CHILD.
(value_of_child): If value_fetch_lazy fails, return NULL
so that callers will be notified that an error occurred.
(c_value_of_variable): Delay check of variable's validity
until later. We actually want all structs and unions to have
the value "{...}".
Do not return "???" for variables which could not be evaluated.
This error condition must be returned to the caller so that it
can get the error condition from gdb.
(cplus_name_of_child): Adjust index for vptr before figuring
out the name of the child.
(cplus_value_of_child): If a child's (real) parent is not valid,
don't even bother trying to give a value for it. Just return
an error. Change all instances in this function.
(cplus_type_of_child): If our parent is one of the "fake"
parents, we need to get at the type of the real parent, and
derive the child's true type using this information.
* symfile.c (generic_load): Whitespace and long line cleanups.
Remove duplicate variable, change several local variables to
more appropriate data types.
(print_transfer_performance): Use %lu instead of %ld for ulongs.
DW_TAG_string_type (this is acceptable under the current DWARF 2.1/3.0
standard.)
2) In read_tag_string_type(), a fix for FORTRAN that propagates the
first string length to all string types. This is important as FORTRAN
strings are not delimited as in C/C++.
3) Handling of the DW_LANG_Fortran95.
* main.c (captured_main): Add new command line option "--pid".
If the second command line argument (following the symbol-file)
begins with a digit, try to attach to it before trying to open
it as a corefile.
(print_gdb_help): Document the "--pid" argument.
* gdb.c++/classes.exp: Accept 'A const' or 'const A' in copy
constructors.
* gdb.c++/derivation.exp: Likewise.
* gdb.c++/templates.exp: Likewise.
* gdb.c++/virtfunc.exp: Likewise.
* gdb.base/gcore.exp: New test for generate-core-file command.
* gdb.base/gcore.c: Testcase for above.
* gdb.threads/gcore-thread.exp: New test for gcore (threaded).
Implement a "generate-core-file" command in gdb, save target state.
* gcore.c: New file. Implement new command 'generate-core-file'.
Save a corefile image of the current state of the inferior.
* linux-proc.c: Add linux-specific code for saving corefiles.
* target.h (struct target_ops): Add new target vectors for saving
corefiles; to_find_memory_regions and to_make_corefile_notes.
(target_find_memory_regions): New macro.
(target_make_corefile_notes): New macro.
* target.c (update_current_target): Inherit new target methods.
(dummy_find_memory_regions): New place-holder method.
(dummy_make_corefile_notes): New place-holder method.
(init_dummy_target): Initialize new dummy target vectors.
* exec.c (exec_set_find_memory_regions): New function.
Allow the exec_ops vector for memory regions to be taken over.
(exec_make_note_section): New function, target vector method.
* defs.h (exec_set_find_memory_regions): Export prototype.
* procfs.c (proc_find_memory_regions): New function, corefile method.
(procfs_make_note_section): New function, corefile method.
(init_procfs_ops): Set new target vector pointers.
(find_memory_regions_callback): New function.
(procfs_do_thread_registers): New function.
(procfs_corefile_thread_callback): New function.
* sol-thread.c (sol_find_memory_regions): New function.
(sol_make_note_section): New function.
(init_sol_thread_ops): Initialize new target vectors.
* inftarg.c (inftarg_set_find_memory_regions): New function.
Allow to_find_memory_regions vector to be taken over.
(inftarg_set_make_corefile_notes): New function.
Allow to_make_corefile_notes vector to be taken over.
* thread-db.c (thread_db_new_objfile): Don't activate thread-db
interface layer if not target_has_execution (may be a corefile).
