@var{letters}. This is used for debugging the RTL-based passes of the
compiler. The file names for most of the dumps are made by appending
a pass number and a word to the @var{dumpname}, and the files are
created in the directory of the output file. @var{dumpname} is
generated from the name of the output file, if explicitly specified

created in the directory of the output file. Note that the pass
number is computed statically as passes get registered into the pass
manager. Thus the numbering is not related to the dynamic order of
execution of passes. In particular, a pass installed by a plugin
could have a number over 200 even if it executed quite early.

Debug dumps can be enabled with a @option{-fdump-rtl} switch or some
@option{-d} option @var{letters}. Here are the possible
