MSVC 18
by Jan Rheinländer 17 Dec '15

17 Dec '15

Hi, I successfully compiled GiNaC (and CLN) with MSVC 18.00.31101 (Visual Studio 2013). All the tests passed, but I had to patch two files: check/exam_cra.cpp ginac/polynomial/mod_gcd.cpp Both of these files require #include <algorithm> otherwise there is an error about 'min' not being a member of namespace std.

With the previous patch, some old workarounds have become unnecessary: If all expressions are evaluated, any object which is an aggregate of expressions will only ever have to evaluate the top level. As such, it has become pointless to evaluate child objects of an expression prior to doing its own term-rewriting. This patch removes the evaluation of children from all GiNaC objects. It also removes the now superfluous parameter 'level' of the eval methods. commit ae6c004bd31e02dda37357d74b641c101b116c73 Author: Richard Kreckel <kreckel(a)ginac.de> Date: Wed Dec 16 13:00:30 2015 +0100 Make add::eval(), mul::eval() work without compromise. If a user asks to evaluate an object, the expectation is that the library returns an evaluated, canonical expression. Everything else is a bug. (It doesn't matter whether the user asks explicitly or by assigning to an ex.) It turns out that it was possible to construct objects which didn't fully evaluate. This patch fixes this by making eval() a little bit more careful. This obsoletes the need to go through combine_ex_with_coeff_to_pair() when constructing an epvector that is then used to construct an add or mul. (Alas, this was omitted frequently enough...) ----------------------------------------------------------------------- Summary of changes: check/exam_inifcns_nstdsums.cpp | 2 +- check/exam_paranoia.cpp | 64 ++++++++++++------------ check/exam_structure.cpp | 2 +- doc/tutorial/ginac.texi | 50 +++++++++---------- ginac/add.cpp | 33 ++++++------- ginac/add.h | 2 +- ginac/basic.cpp | 2 +- ginac/basic.h | 2 +- ginac/container.h | 32 ------------ ginac/ex.cpp | 2 +- ginac/ex.h | 6 +-- ginac/expairseq.cpp | 78 ++++++++++++----------------- ginac/expairseq.h | 4 +- ginac/factor.cpp | 2 - ginac/fderivative.cpp | 7 +-- ginac/fderivative.h | 2 +- ginac/function.cppy | 7 ++- ginac/function.hppy | 2 +- ginac/indexed.cpp | 6 +-- ginac/indexed.h | 2 +- ginac/inifcns_nstdsums.cpp | 2 +- ginac/integral.cpp | 22 +++------ ginac/integral.h | 2 +- ginac/matrix.cpp | 21 -------- ginac/matrix.h | 4 -- ginac/mul.cpp | 33 ++++++++----- ginac/mul.h | 2 +- ginac/ncmul.cpp | 17 +++---- ginac/ncmul.h | 2 +- ginac/normal.cpp | 8 +-- ginac/numeric.cpp | 4 +- ginac/numeric.h | 2 +- ginac/power.cpp | 107 ++++++++++++++++++---------------------- ginac/power.h | 2 +- ginac/pseries.cpp | 12 ++--- ginac/pseries.h | 2 +- ginac/relational.cpp | 11 ----- ginac/relational.h | 1 - ginac/structure.h | 2 +- ginac/symbol.h | 2 +- ginsh/ginsh_parser.ypp | 13 +---- 41 files changed, 225 insertions(+), 353 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

There seems to be no way to obsolete the need to mark an object derived from basic and handled by ex as being 'on the heap', at least none that doesn't have significant performance impact. Having said that, this patch aims at making this process simpler and more intuitive. Where, before, one would return from a function returning an ex with return (new mul(a, b))->setflag(status_flags::dynallocated); this patch lets us return with return dynallocate<mul>(a, b); which should be much clearer. In any case, it involves less typing. The two points where the status_flags::dynallocated are set are now * the dynallocate<B>(args...) template function and * the virtual duplicate() member functions. This patch rolls out the new functionality throughout the library. ----------------------------------------------------------------------- Summary of changes: check/exam_factor.cpp | 2 +- check/exam_mod_gcd.cpp | 2 +- ginac/add.cpp | 51 ++++++++------------ ginac/basic.cpp | 4 +- ginac/basic.h | 34 ++++++++++++- ginac/clifford.cpp | 53 ++++++++++----------- ginac/color.cpp | 10 ++-- ginac/ex.cpp | 25 ++-------- ginac/expairseq.cpp | 2 +- ginac/function.cppy | 3 +- ginac/idx.cpp | 13 +++-- ginac/indexed.cpp | 19 ++++---- ginac/inifcns.cpp | 2 +- ginac/inifcns_trans.cpp | 4 +- ginac/integral.cpp | 15 ++---- ginac/matrix.cpp | 28 +++++------ ginac/mul.cpp | 55 ++++++++++----------- ginac/ncmul.cpp | 41 +++++++--------- ginac/normal.cpp | 83 ++++++++++++++++---------------- ginac/numeric.cpp | 21 ++++---- ginac/operators.cpp | 8 ++-- ginac/parser/parse_binop_rhs.cpp | 14 +++--- ginac/polynomial/collect_vargs.cpp | 4 +- ginac/polynomial/divide_in_z_p.cpp | 2 +- ginac/polynomial/euclid_gcd_wrap.h | 2 +- ginac/power.cpp | 86 ++++++++++++++------------------- ginac/power.h | 4 +- ginac/pseries.cpp | 30 +++++------- ginac/registrar.h | 7 ++- ginac/relational.cpp | 4 +- ginac/symbol.h | 14 +++++- ginac/symmetry.cpp | 24 +++++----- ginac/tensor.cpp | 18 +++---- ginac/utils.cpp | 98 +++++++++++++++++++------------------- 34 files changed, 378 insertions(+), 404 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
