add #include guard hack 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. [Bug #16770] *1: https://docs.microsoft.com/en-us/cpp/preprocessor/once *2: https://gcc.gnu.org/onlinedocs/cppinternals/Guard-Macros.html

split internal.h into files 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.

void rb_gc_mark_global_tbl(void);
Allow global variables to move This patch allows global variables that have been assigned in Ruby to move. I added a new function for the GC to call that will update global references and introduced a new callback in the global variable struct for updating references. Only pure Ruby global variables are supported right now, other references will be pinned.

Use ID instead of GENTRY for gvars. (#3278) Use ID instead of GENTRY for gvars. Global variables are compiled into GENTRY (a pointer to struct rb_global_entry). This patch replace this GENTRY to ID and make the code simple. We need to search GENTRY from ID every time (st_lookup), so additional overhead will be introduced. However, the performance of accessing global variables is not important now a day and this simplicity helps Ractor development.
