I went down that rabbit hole researching why Don Knuth had a high opinion of it.
If you dig around, the IL is described in the SDS Fortran documentation
http://bitsavers.org/pdf/sds/9xx/lang/900883A_9300_FORTRAN_IV_Tech_Aug65.pdf
and http://bitsavers.org/pdf/digitek/Data_Structures_in_Digiteks_FORTRAN_IV_Compiler_for_the_SDS_900_Series.pdf

and a compiler listing
