Re: [Gems-users] Interaction between Ruby and benchmarks

["Dave Z." <zhu_dave@xxxxxxxxx>]

I've looked at the LogTM release (ruby/log_tm), and
I've found some functions (addMagicEntry,
undoMagicEntry) that might be related with magic
instructions in TransactionLog.[Ch], but I couldn't
find any files including "magic_instruction". Am I
looking at the wrong place?

Thanks.
