* Add include/linux/stringify.h from Linux kernel 2.6.12-rc2 (cherry picked from commit torvalds/linux@1da177e) * Make __stringify support variable argument macros too For example: __stringify(__entry->irq, __entry->ret) will now convert it to: "REC->irq, REC->ret" It also still supports single arguments as the old macro did.

Works with the newest versions of ICCAVR, GCC, CLANG and MSCV. C++11 may be required. * Adjust to ETL folder structure. * Change include guard to the one usual in ETL. * Add definition guard for STRINGIFY. --------- Co-authored-by: Linus Torvalds <torvalds@ppc970.osdl.org> Co-authored-by: Zhaolei <zhaolei@cn.fujitsu.com>

… 2 arguments. Inspired by https://stackoverflow.com/a/11763277/ Warning: This requires support for variadic macros (`__VA_ARGS__`). These were officially added in C99 and C++11.

I've just managed to get round to looking at this pull request and I noticed that it has a lot of 'co-authors', one at least involved with Linux. Has some of this change been copied from GPL code? Co-authored-by: John Wellbelove jwellbelove@users.noreply.github.com |

The branch contains some commits which were not supposed to be merged. A rebase is required to remove those, hence I did not mark the pull request as ready for merge. I was not able to finish this pull request as I was not able to use the build pipeline to test the changes (see #784). The only relevant changes for this pull request is the range including [7771cf3 ... ba53a39] (see comparison with parent). Those commits were authored my me. |
Suggested changes:
ETL_STATIC_ASSERT()for only one argument (condition). That overload does either callstatic_assert()if C++17 is used or callsETL_STATIC_ASSERT()where the second (message) argument is generated by stringifying the condition.⚠ Warning: The overload resolution mechanism does use variadic macros (
__VA_ARGS__). These were officially added in C99 and C++11. When compiling with-std=c++98modern compilers issue a warning (see example). I also tested it with IAR C/C++ Compiler for AVR 6.70.1 which officially only supports C++98 (Extended Embedded C++), without warnings or errors.In case these changes are accepted, the documentation on the website must be updated.
