registers.

structure.

AltiVec register to new builtin type.

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.

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.

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.
