Note we removed SET_TYPE in 2004 for lack of in-tree uses (there was a suspicion it might have been for Pascal, but GNU Pascal is now a moribund project (largely I think because of the combination of (a) being closely tied to GCC internals through use of trees as front-end internal representation and (b) not being developed in the GCC repository but externally with attempts to support multiple GCC versions from one GNU Pascal version, meaning lots of effort needed outside the GCC community to update it to new GCC versions - also (c) there's another more actively developed GPL Pascal compiler, Free Pascal, albeit for different versions of the Pascal language). In general, for GCC development to consider requirements of your front end or back end, getting it into the GCC repository and developing it there is strongly recommended. -- Joseph S.
