+# Static declaration of BIFs that should execute on dirty schedulers.
+#
+# <dirty-bif-decl> ::= <type> <bif>
+# <bif> ::= <module> ":" <name> "/" <arity>
+# <type> ::= dirty-cpu | dirty-io | dirty-cpu-test | dirty-io-test
+#
+# When dirty scheduler support is available, a BIF declared with the
+# 'dirty-cpu' type will unconditionally execute on a dirty CPU scheduler,
+# and a BIF declared with the type 'dirty-io' will unconditionally execute
+# on a dirty IO scheduler. When dirty scheduler support is not available
+# all BIFs will of course execute on normal schedulers.
+#
+# When the emulator has been configured with the debug option
+# '--enable-dirty-schedulers-test', BIFs with the types 'dirty-cpu-test',
+# and 'dirty-io-test' will unconditionally execute on dirty schedulers.
+# When this debug option has not been enabled, these BIFs will be executed
+# on normal schedulers.
+#
+# BIFs marked as 'ubif' in ./bif.tab will be ignored, i.e., will always
+# execute on normal schedulers.

+#  Functions below will execute on dirty schedulers when emulator has
+#  been configured for testing dirty schedulers. This is used for test
+#  and debug purposes only. We really do *not* want to execute these
+#  on dirty schedulers on a real system.
