--- Comment #1 from Ilya Enkovich <enkovich.gnu at gmail dot com> --- For call arguments we usually store bounds passed in bounds tables and then fill bounds passed in registers. But with -fschedule-insns we have order changed and all hard registers are filled with values before BNDSTX. This is not a nice schedule because it requires additional spills. Seems LRA fails to spill a register when all of them are used to pass args. This situation didn't happen before because bounds registers is the first case when we use all registers to pass args. Should LRA be able to spill/fill initialized hard reg? Can it be fixed or we better avoid such scheduling?
