Not using STL iterators makes the code simpler and cleaner. Also we don't have to argue whether the standard ([lib.random.access.iterators]) imposes any pre/post-condictions on operator+=. commit 694f839947982f5b12b6c629d5bab522c801630d Author: Alexei Sheplyakov <varg@metalica.kh.ua> Date: Sat Aug 8 13:03:48 2009 +0300 shaker_sort, permutation_sign: fix invalid use of STL iterators. According to the standard incrementing end(), and decrementing begin() are ill-defined operations (see [lib.forward.iterators], [lib.bidirectional.iterators]). commit 526825bcee294cb20e37d8db6d5040ba0f8c428f Author: Alexei Sheplyakov <varg@metalica.kh.ua> Date: Sat Aug 8 13:07:14 2009 +0300 symmetry::calchash(): be careful to not dereference past-the-end iterator. commit 49a44f7d55ec0d6686d3c32c7081a07d10c93274 Author: Alexei Sheplyakov <varg@metalica.kh.ua> Date: Sat Aug 8 13:06:36 2009 +0300 check_parameter_G: fix pontential increment of end(). Incrementing past-the-end iterator is not permitted by the standard, see [lib.input.iterators]. commit dda45abd8a2c408f8b3eb7959a10dfb2468ecc3a Author: Alexei Sheplyakov <varg@metalica.kh.ua> Date: Sat Aug 8 13:02:47 2009 +0300 G_eval: fix incorrect use of STL iterator. According to [lib.bidirectional.iterators] it's not OK to decrement an iterator pointing to the beginning of the sequence. Fortunately random access iterators provided by (current versions of) gcc/libstdc++ don't have this silly limitation, so the code which works with pointers works with iterators without any changes at all. However, - there's no guarantee that the current behavior won't change in the future - some non-GNU compilers are not that smart (i.e. the program segfaults upon when decrementing beginning-of-the-sequence iterator). ----------------------------------------------------------------------- Summary of changes: ginac/factor.cpp | 60 +++++++++++++++++--------------------------- ginac/inifcns_nstdsums.cpp | 7 +++- ginac/symmetry.cpp | 3 +- ginac/utils.h | 24 +++++++++++++---- 4 files changed, 48 insertions(+), 46 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
