As you've seen, in the current development sources,
GO_IF_LEGITIMATE_ADDRESS has been replaced by
TARGET_LEGITIMATE_ADDRESS_P.  I assume you are doing your port using
some older version of gcc.  If you run "make pdf" in the gcc
subdirectory of a configured build directory, you will get a copy of
the internals manual for the version of gcc that you are using.  It
will be called gccint.pdf.  Or you can just read the texinfo source
files for the manual, they are fairly readable.

GO_IF_LEGITIMATE_ADDRESS jumps to a label if the address is
legitimate.
