GCC GENERIC is an intermediate representation language created in 2003.
| #3424on PLDB | 21Years Old |
The purpose of GENERIC is simply to provide a language-independent way of representing an entire function in trees. To this end, it was necessary to add a few new tree codes to the backend, but most everything was already there. If you can say it with the codes in gcc/tree.def, it’s GENERIC.
