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.

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.

should not use rb_ary_modify() ractor_copy() used rb_ary_modify() to make sure this array is not sharing anything, but it also checks frozen flag. So frozen arrays raises an error. To solve this issue, this patch introduces new function rb_ary_cancel_sharing() which makes sure the array does not share another array and it doesn't check frozen flag.

[Feature #18901] Support size pool movement for Arrays This commit enables Arrays to move between size pools during compaction. This can occur if the array is mutated such that it would fit in a different size pool when embedded. The move is carried out in two stages: 1. The RVALUE is moved to a destination heap during object movement phase of compaction 2. The array data is re-embedded and the original buffer free'd if required. This happens during the update references step

Add RARRAY_LITERAL_FLAG for array literals Array created as literals during iseq compilation don't need a reference count since they can never be modified. The previous implementation would mutate the hidden array's reference count, causing copy-on-write invalidation. This commit adds a RARRAY_LITERAL_FLAG for arrays created through rb_ary_literal_new. Arrays created with this flag do not have reference count stored and just assume they have infinite number of references. Co-authored-by: Jean Boussier <jean.boussier@gmail.com>

Add comments about special runtime routines YJIT calls When YJIT make calls to routines without reconstructing interpreter state through jit_prepare_routine_call(), it relies on the routine to never allocate, raise, and push/pop control frames. Comment about this on the routines that YJTI calls. This is probably something we should dynamically verify on debug builds. It's hard to statically verify this as it requires verifying all functions in the call tree. Maybe something to look at in the future.

decouple internal.h headers Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
