"What will Stephen Fry say to him, her, or it?" "I'd say, bone cancer in children? What's that about?" Fry replied. "How dare you? How dare you create a world to which there is such misery that is not our fault. It's not right, it's utterly, utterly evil." "Why should I respect a capricious, mean-minded, stupid God who creates a world that is so full of injustice and pain. That's what I would say." |

I have the awful feeling that you may have missed the joke. But probably you are meeting irony with more irony. |

Thanks in advance. I've made some progress on this now and have checked in support for base_collection here: https://github.com/Ebenezer-group/onwards https://github.com/Ebenezer-group/onwards/tree/master/poly Here's some code generated by the C++ Middleware Writer : https://github.com/Ebenezer-group/onwards/blob/master/poly/zz.testing.hh based on these two input files: https://github.com/Ebenezer-group/onwards/blob/master/poly/testing.hh https://github.com/Ebenezer-group/onwards/blob/master/poly/testing.mdl Thanks a lot to Joaquín López Muñoz, the author of the PolyCollection library, for answering a number of questions I had.

| computer45 <computer45@cyber.com>: Mar 19 09:20PM -0400 Hello.. About scalable reference counting.. I have found this Scalable Reference Counting Garbage Collector, and i think it is the only one invented by two PhDs from Israel: http://www.cs.technion.ac.il/users/wwwb/Reports/1999/CS0967.pdf So i have decided to invent and to implement another fully scalable reference counting algorithm with efficient support for weak references, it is fully scalable on multicores and manycores systems and here it is: https://sites.google.com/site/aminer68/scalable-reference-counting-with-efficient-support-for-weak-references Hope you will be happy with my project , because since i "love" Delphi, i have decided to bring the "best" to Delphi, my salable reference counting algorithm can be ported to C++Builder or to other C++ compilers also. Thank you, Amine Moulay Ramdane. |

Most preprocessor metaprogramming will break, same names in anonymous namespaces may conflict and same names of statics may conflict. I did not check if Brian's code has any of that. Otherwise works. |

In my own code I had to make static function names unique manually. For template code, I think the template code must be merged in a single header file. And the source code merged in other file without to expand the template headers. Instead it must include one merged template file. If I had to to this using the tool I would do the following: 1 - Merge all includes in one file tool merge_h.txt allheaders.h -- merge_h.txt-- #include "header1.h" #include "header2.h" ... #include "headerN.h" --- 2 - Merge source files. Headers files must not be present in this directory to avoid expansion. They need to be included at the beginning to avoid subsequent includes of "#include". tool merge_cpp.txt allsource.cpp -- merge_cpp.txt-- ////////////cut here after completation /////////////////// #include "header1.h" #include "header2.h" ... #include "headerN.h" ///////////cut here after completation ///////////// #include "allheaders.h" #include "source1.cpp" #include "source2.cpp" ... #include "sourceN.cpp" --- After generation allsource.cpp I would manually remove cut here, or just use #if 0 there. I don't have a real case for this now, but the tool can be customized for the template needs. I can create the "don't expand list" also to avoid to have to remove the headers I don't want to expand. |

Disagree. Using typedef to give otherwise non-descript generic types meaningful names is a good idea which I employ a lot. C++ has also introduced the 'auto' keyword which hides the original type. /Flibble |
| "Chris M. Thomasson" <invalid_chris_thomasson@invalid.invalid>: Mar 20 01:24AM -0700 I have always used my custom asm for this, but I noticed a while ago that C++11 can use Double-Width Compare-and-Swap (DWCAS) via a struct the size of two pointers for atomic operations. Out of interest, I have constructed the following program that works on MSVC 14.0.25424.00 Update 3. However, on GCC 6.3.0, I am getting the following errors: ____________________________ ||=== Build: Debug in ct_experiment (compiler: GNU GCC Compiler) ===| obj\Debug\main.o||In function `std::atomic<ct_dwcas>::is_lock_free() const':| C:\msys64\mingw64\include\c++\6.3.0\atomic|212|undefined reference to `__atomic_is_lock_free'| obj\Debug\main.o||In function `std::atomic<ct_dwcas>::load(std::memory_order) const':| C:\msys64\mingw64\include\c++\6.3.0\atomic|235|undefined reference to `__atomic_load_16'| obj\Debug\main.o||In function `std::atomic<ct_dwcas>::compare_exchange_weak(ct_dwcas&, ct_dwcas, std::memory_order, std::memory_order)':| C:\msys64\mingw64\include\c++\6.3.0\atomic|268|undefined reference to `__atomic_compare_exchange_16'| ||error: ld returned 1 exit status| ||=== Build failed: 4 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===| ____________________________ Here is the code: ____________________________ #if defined (_MSC_VER) # define _ENABLE_ATOMIC_ALIGNMENT_FIX // for dwcas
