--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
I can confirm that with GCC 14 enabling -fmodulo-sched over -O1
-fschedule-insns2 increases memory use from 350MB to 1.5GB.
Of course modulo scheduling is hardly maintained.
SMS is a happy user of sbitmap which is hardly a space efficient data
structure.
