09:59 PM Ruby Feature #21929 (Feedback): Add configure script options for instrumenting Rust builds

It's hard for me to tell what's desired beyond the already merged PR you proposed. It seems to be about some mechanism for flag overriding for development builds that use `cargo`, but sort of by definition packaging is not a great fit fo... alanwu (Alan Wu)

06:03 PM Ruby Revision 8466e93b (git): YJIT: Fix not reading locals from `cfp->ep` after `YJIT.enable` and exceptional entry

[Backport #21941]
In case of `--yjit-disable`, YJIT only starts to record environment
escapes after `RubyVM::YJIT.enable`. Previously we falsely assumed that
we always have a full history all the way back to VM boot. This had YJIT

04:08 PM Ruby Revision 1a0e67d3 (git): ZJIT: `::RubyVM::ZJIT.induce_side_exit!` and `induce_compile_failure!`

Tells ZJIT to do a side exit or to fail to compile, useful testing and
for bug reports. We are picky about the syntactic form so we can tell
where the call lands early in the compiler pipeline. The `::` prefix
allows us to interpret it w... alanwu (Alan Wu)

06:07 PM Ruby Revision a2b9c8a5 (git): ZJIT: Avoid `NoSingletonClass` patchpoint when already a singleton class

The true purpose of assume_no_singleton_classes() is to retain soundness
in event of the effective class of values changing. When the effective
class is already a singleton class that can never happen. (Except due to
IO#reopen, but that'... alanwu (Alan Wu)
