| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Object Shapes is used for accessing instance variables and representing the "frozenness" of objects. Object instances have a "shape" and the shape represents some attributes of the object (currently which instance variables are set and the "frozenness"). Shapes form a tree data structure, and when a new instance variable is set on an object, that object "transitions" to a new shape in the shape tree. Each shape has an ID that is used for caching. The shape structure is independent of class, so objects of different types can have the same shape. For example: ```ruby class Foo def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end class Bar def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end foo = Foo.new # `foo` has shape id 2 bar = Bar.new # `bar` has shape id 2 ``` Both `foo` and `bar` instances have the same shape because they both set instance variables of the same name in the same order. This technique can help to improve inline cache hits as well as generate more efficient machine code in JIT compilers. This commit also adds some methods for debugging shapes on objects.

* RBASIC_SET_CLASS_RAW: follow strict aliasing rule卜部昌平2021-03-021-2/+2
| | | | | | | | Instead of rather euphemistic struct cast, just reomve the const qualifier and assign directly. According to ISO/IEC 9899:2018 section 6.5 paragraph 7, `VALUE` and `const VALUE` are allowed to alias (but two distinct structs are not, even when their structures are the same). [Bug #17540]
* ROBJECT_IV_INDEX_TBL: convert into an inline function卜部昌平2020-08-191-0/+22
| | | | | | | Former ROBJECT_IV_INDEX_TBL macro included RCLASS_IV_INDEX_TBL, which is not disclosed to extension libraies. The macro was kind of broken. Why not just deprecate it, and convert the internal use into an inline function.
* inline Primitive.cexpr!卜部昌平2020-07-131-0/+1
| | | | | We can obtain the verbatim source code of Primitive.cexpr!. Why not paste that content into the JITed program.
* add #include guard hack卜部昌平2020-04-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | 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.

* internal/object.h rework卜部昌平2019-12-261-18/+33
| | | | | | Eliminated macros. As a side effect struct RBasicRaw is no longer required because we can now define anonymous structs inside of inline functions.
* split internal.h into files卜部昌平2019-12-261-0/+45
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.
