Drop mswin support of MJIT (#6265)

2022-08-21T01:35:36+00:00

The current MJIT relies on SIGCHLD and fork(2) to be performant, and
it's something mswin can't offer. You could run Linux MJIT on WSL
instead.

[Feature #18249] Implement ABI checking

2022-02-22T14:55:21+00:00

Header file include/ruby/internal/abi.h contains RUBY_ABI_VERSION which
is the ABI version. This value should be bumped whenever an ABI
incompatible change is introduced.

When loading dynamic libraries, Ruby will compare its own
`ruby_abi_version` and the `ruby_abi_version` of the loaded library. If
these two values don't match it will raise a `LoadError`. This feature
can also be turned off by setting the environment variable
`RUBY_RUBY_ABI_CHECK=0`.

This feature will prevent cases where previously installed native gems
fail in unexpected ways due to incompatibility of changes in header
files. This will force the developer to recompile their gems to use the
same header files as the built Ruby.

In Ruby, the ABI version is exposed through
`RbConfig::CONFIG["ruby_abi_version"]`.

Mark some JIT-ed functions as COLDFUNC

2020-05-18T05:21:31+00:00

Put some functions which are unlikely to be called on JIT in
.text.unlikely section to improve hot code's locality.

Stop always inlining not-optimized get/setivar

2020-05-13T05:50:05+00:00

As we have the optimization in _mjit_compile_ivar.erb, we don't use
these functions if we successfully optimize ivars. Therefore it's
consuming code size where we can't optimize it well.

To decrease code size, we'd better avoid inlining them.

This didn't exist in my machine, but it may exist in some CI
