add #include guard hack 2020-04-13T07:06:00+00:00 卜部昌平 shyouhei@ruby-lang.org 2020-04-10T05:11:40+00:00 4ff3f205408ff8bb413d69151105d301858136ba According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

other minior internal header tweaks 2019-12-26T11:45:12+00:00 卜部昌平 shyouhei@ruby-lang.org 2019-12-03T05:47:38+00:00 bf53d6c7d19f877c821901b3288d7f80955ffbb7 These headers need no rewrite. Just add some minor tweaks, like addition of #include lines. Mainly cosmetic. TIMET_MAX_PLUS_ONE was deleted because the macro was used from only one place (directly write expression there).

split internal.h into files 2019-12-26T11:45:12+00:00 卜部昌平 shyouhei@ruby-lang.org 2019-11-29T06:18:34+00:00 b739a63eb41f52d33c33f87ebc44dcf89762cc37 One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.
