A lot of the code you'll need already exists in emit-rtl.c. That code should be split out to a new file and be shared between rtl and gimple. You'll probably want to make block_locators_locs, block_locators_blocks, and locations_locators_locs part of struct function. The biggest challenges will be avoiding bloat and managing the locators for inlining/cloning... Ciao! Steven
