Memory Management Debugger

Valgrind checks all memory operations in an application, like read,
write, malloc, new, free, and delete. Valgrind can find uses of
uninitialized memory, access to already freed memory, overflows,
illegal stack operations, memory leaks, and any illegal
new/malloc/free/delete commands. Another program in the package is
"cachegrind," a profiler based on the valgrind engine.

To use valgrind you should compile your application with "-g -O0"
compiler options. Afterwards you can use it with:

valgrind --tool=memcheck --sloppy-malloc=yes --leak-check=yes
--db-attach=yes my_application, for example.

More valgrind options can be listed via "valgrind --help". There is
also complete documentation in the /usr/share/doc/packages/valgrind/
directory. A debugged application runs slower and needs much more
memory, but is usually still usable. Valgrind is still in development,
but it has been successfully used to optimize several KDE applications.

Revision 2 (latest revision is 3)

Gustavo Yokoyama Ribeiro (gyribeiro) committed over 3 years ago (revision 2)

- update to 3.16.1 (jsc#SLE-13769):
  * PPC sync instruction L field should only be 2 bits in ISA 3.0
  * vex: the `impossible' happened: expr_is_guardable: unhandled expr
- remove 0001-Power-PC-Fix-extraction-of-the-L-field-for-sync-inst.patch (upstream)

- Use autopatch
  - Change armv6-support.diff to a/b format

- update to 3.16.0:
  * Many bugfixes, too many to list here, see NEWS file
  - The implicit memcpy done by each call to realloc now counts towards the
    read and write counts of resized heap blocks, making those counts higher
    and more accurate.
  - cg_annotate's --auto and --show-percs options now default to 'yes', because
    they are usually wanted.
  - callgrind_annotate's --auto and --show-percs options now default to 'yes',
    because they are usually wanted.
  - The command option --collect-systime has been enhanced to specify
    the unit used to record the elapsed time spent during system calls.
    The command option now accepts the values no|yes|msec|usec|nsec,
    where yes is a synonym of msec.  When giving the value nsec, the
    system cpu time of system calls is also recorded.
  - Several memcheck options are now dynamically changeable.
    Use  valgrind --help-dyn-options  to list them.
  - The release 3.15 introduced a backward incompatible change for
    some suppression entries related to preadv and pwritev syscalls.
    When reading a suppression entry using the unsupported 3.14 format,
    valgrind will now produce a warning to say the suppression entry will not
    work, and suggest the needed change.
  - Significantly fewer false positive errors on optimised code generated by
