Says to make debugging dumps during compilation at times specified by
@var{letters}. This is used for debugging the compiler. The file names
for most of the dumps are made by appending a pass number and a word to
-the source file name (e.g. @file{foo.c.00.rtl} or @file{foo.c.01.jump}).
+the source file name (e.g. @file{foo.c.00.rtl} or @file{foo.c.01.sibling}).
Here are the possible letters for use in @var{letters}, and their meanings:
