-# This is a hack we use to generate .py files with constants for Python
-# pretty printers.  It works the same way as gen-as-const.
-# See scripts/gen-py-const.awk for details on how the awk | gcc mechanism
-# works.
-#
-# $@.tmp and $@.tmp2 are temporary files we use to store the partial contents
-# of the target file.  We do this instead of just writing on $@ because, if the
-# build process terminates prematurely, re-running Make wouldn't run this rule
-# since Make would see that the target file already exists (despite it being
-# incomplete).
-#
-# The sed line replaces "@name@SOME_NAME@value@SOME_VALUE@" strings from the
-# output of 'gcc -S' with "SOME_NAME = SOME_VALUE" strings.
-# The '-n' option, combined with the '/p' command, makes sed output only the
-# modified lines instead of the whole input file.  The output is redirected
-# to a .py file; we'll import it in the pretty printers file to read
-# the constants generated by gen-py-const.awk.
-# The regex has two capturing groups, for SOME_NAME and SOME_VALUE
-# respectively.  Notice SOME_VALUE may be prepended by a special character,
-# depending on the assembly syntax (e.g. immediates are prefixed by a '$'
-# in AT&T x86, and by a '#' in ARM).  We discard it using a complemented set
-# before the second capturing group.
