New build option to enable/disable global method caching

Added by shugo (Shugo Maeda) about 10 years ago. Updated about 10 years ago.

Status:
Closed
Priority:
Normal
Target version:

ruby -v:
ruby 2.0.0dev (2012-10-05 trunk 37093) [i686-linux]
Backport:

Description

Ruby has a build option to enable/disable inline method caching (OPT_INLINE_METHOD_CACHE), but has no such option for global method caching.
How about to add a new build option OPT_GLOBAL_METHOD_CACHE?

I've attached a patch to add that option.

I don't have any objection.
Where is a patch?

It is okay. But I recommend that only method search at the the
`rb_method_entry_get_with_omod' should be disable to measure and compare
performance.
