When ada-lang transforms an array descriptor type (an XUP structure) into an array type, the size of the array type is computed by using the element size, and multiplying it by the number of elements in that array. This does not work, however, for packed arrays, where the *packed* size in bits needs to be used. This usually does not cause any problem, because we end up reading more memory than needed. However, we have observed on LynxOS a memory error while trying to read the entire array, because the larger-than-needed read tried to read past the end of the stack into inaccessible memory. This patch fixes the problem by correctly computing the array size in bytes in the case of packed arrays. gdb/ChangeLog: * ada-lang.c (ada_type_of_array): Fix the size of the array in the case of an unconstrained packed array. gdb/testsuite/ChangeLog: * gdb.ada/packed_array: Expand testcase to test printing of unconstrained packed array. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
