David Green	2fea3fe41c	[MachineScheduler] Update available queue on the first mop of a new cycle ... If a resource can be held for multiple cycles in the schedule model then an instruction can be placed into the available queue, another instruction can be scheduled, but the first will not be taken back out if the two instructions hazard. To fix this make sure that we update the available queue even on the first MOp of a cycle, pushing available instructions back into the pending queue if they now conflict. This happens with some downstream schedules we have around MVE instruction scheduling where we use ResourceCycles=[2] to show the instruction executing over two beats. Apparently the test changes here are OK too. Differential Revision: https://reviews.llvm.org/D76909	2020-06-09 19:13:53 +01:00
Nemanja Ivanovic	64b31d96df	[PowerPC] Do not attempt to reuse load for 64-bit FP_TO_UINT without FPCVT ... We call the function that attempts to reuse the conversion without checking whether the target matches the constraints that the callee expects. This patch adds the check prior to the call.
