end

#rewrite(pass:, reason:, file:, line:) ⇒ Object

An optimization site that actually rewrote IR. Feeds fixed-point termination via rewrite_count.

# File 'lib/optimize/log.rb', line 21

def rewrite(pass:, reason:, file:, line:)
  @entries << Entry.new(pass: pass, reason: reason, file: file, line: line)
  @rewrite_count += 1
end

#skip(pass:, reason:, file:, line:) ⇒ Object

An optimization site that declined to rewrite. Does NOT count toward rewrite_count — fixed-point iteration must not treat a decline as a change.
