"Finer-grained inline constant cache invalidation"
MSWin builds on AppVeyor have been crashing since the merger.
Current behavior - caches depend on a global counter. All constant mutations cause caches to be invalidated.
```ruby
class A
B = 1
end
def foo
A::B # inline cache depends on global counter
end
foo # populate inline cache
foo # hit inline cache
C = 1 # global counter increments, all caches are invalidated
foo # misses inline cache due to `C = 1`
```
Proposed behavior - caches depend on name components. Only constant mutations with corresponding names will invalidate the cache.
```ruby
class A
B = 1
end
def foo
A::B # inline cache depends constants named "A" and "B"
end
foo # populate inline cache
foo # hit inline cache
C = 1 # caches that depend on the name "C" are invalidated
foo # hits inline cache because IC only depends on "A" and "B"
```
Examples of breaking the new cache:
```ruby
module C
# Breaks `foo` cache because "A" constant is set and the cache in foo depends
# on "A" and "B"
class A; end
end
B = 1
```
We expect the new cache scheme to be invalidated less often because names aren't frequently reused. With the cache being invalidated less, we can rely on its stability more to keep our constant references fast and reduce the need to throw away generated code in YJIT.
Use ISEQ_BODY macro to get the rb_iseq_constant_body of the ISeq. Using
this macro will make it easier for us to change the allocation strategy
of rb_iseq_constant_body when using Variable Width Allocation.
For the case using this script as a library.
- `ExtLibs#process` reads and processes an extlibs file.
- `ExtLibs#process_under` processes all extlibs files under the
given directory.
- `Extlibs.run` parses `ARGV` and lets an instance process the
directories.
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"]`.
On the parallel test, workers can be killed because of timeout
and the information for the retrying can be inconsistent.
This patch will skip if the inconsistency is found and report
as an error.

Issue only occurs in JRuby 9.3.0.0 and Windows and the full
console output is:
log rotation inter-process lock failed. D:\log.txt -> D:\log.txt.0: The process cannot access the file because it is being used by another process.
log writing failed. closed stream
log writing failed. closed stream

The gem doesn't even install on old rubies, but since the gemspec claims
it's supported, `gem install pathname` will try to install it and print
an error.
This commit doesn't fix the above issue. The only way to fix it would be
to restore support and release a new version that actually supports old
rubies. However, such a change has been proposed and ignored for a long
time.
So this issue proposes to leave that broken but at least bring the
gemspec manifest and the CI matrix in sync to hopefully avoid this issue
from happening again in the future.

configure.ac: setup build tools and register objects
main.c: wrap main with rb_wasm_rt_start to handle asyncify unwinds
tool/m4/ruby_wasm_tools.m4: setup default command based on WASI_SDK_PATH
environment variable. checks wasm-opt which is used for asyncify.
tool/wasm-clangw wasm/wasm-opt: a clang wrapper which replaces real
wasm-opt with do-nothing wasm-opt to avoid misoptimization before
asyncify. asyncify is performed at POSTLINK, but clang linker driver
tries to run optimization by wasm-opt unconditionally. inlining pass
at wasm level breaks asyncify's assumption, so should not optimize
before POSTLIK.
wasm/GNUmakefile.in: wasm specific rules to compile objects
When building with --with-static-linked-ext, some exts without rb file
doesn't produce neither .so or .rb under .ext/common. Therefore, change
rbinstall.rb to install gemspec even if there is no .so or .rb for that
case.
