Subject: [ruby-core:62764] [ruby-trunk - Feature #9638] [PATCH] limit IDs to 32-bits on 64-bit systems

Issue #9638 has been updated by Naohisa Goto.


I'm using machines that have 2TB or more main memory. I think the machines can treat more than 2**32 symbols and I want to use full 64-bit capacity.

----------------------------------------
Feature #9638: [PATCH] limit IDs to 32-bits on 64-bit systems
https://bugs.ruby-lang.org/issues/9638#change-46881

* Author: Eric Wong
* Status: Open
* Priority: Low
* Assignee: 
* Category: core
* Target version: current: 2.2.0
----------------------------------------
This should allow better use of cache-friendly lookup mechanisms such as
funny_falcon's sparse array in [ruby-core:55079]

Also limits symbol space to prevent OOM.

Some structs may also be made smaller as a result (rb_method_entry_t).

We're changing ABI for 2.2.0 anyways, so this is a good time to introduce
this change.
