Hi!Richard, you may remember your words from <https://gcc.gnu.org/PR46805> "ICE: SIGSEGV in optab_for_tree_code (optabs.c:407) with -O -fno-tree-scev-cprop -ftree-vectorize":Ideally we'd never use lang_hooks.types.type_for_mode (or _for_size) in the middle-end but had a pure middle-end based implementation.Is there a canonical PR or other discussion thread for that?
