-# "ubif" is an unwrapped bif, i.e. a bif without a trace wrapper,
-# or rather; the trace entry point in the export entry is the same
-# as the normal entry point, and no trace wrapper is generated.
+# ubif:   Use for operators and guard BIFs that never build anything
+#         on the heap (such as tuple_size/1) and operators.
 #
-# Important: Use "ubif" for guard BIFs and operators; use "bif" for ordinary BIFs.
+# gcbif:  Use for guard BIFs that may build on the heap (such as abs/1).
+#
+# bif:    Use for all other BIFs.

 # Add new BIFs to the end of the file.

-# Note: Guards BIFs require special support in the compiler (to be able to actually
-# call them from within a guard).
