inductor: fix compile error for inplace variable multi-defined (#106852) When removing an inplace buffer, we just mark it as ```REMOVED```, after removing some inplace buffer, and then if we mark a buffer as inplace buffer using the ```self.inplace_buffer.values()``` length to create a buffer name, there may have an issue which we may define a same inplace buffer name with existed in ```self.inplace_buffer.values()```: before removing some inplace buffers, the ```self.inplace_buffers``` may be like: ``` {'buf0': InplacedBuffer(inner_name='in_out_ptr0', other_names=['buf0', 'buf2', 'buf4']), 'buf2': InplacedBuffer(inner_name='in_out_ptr0', other_names=['buf0', 'buf2', 'buf4']), 'buf4': InplacedBuffer(inner_name='in_out_ptr0', other_names=['buf0', 'buf2', 'buf4']), 'buf5': InplacedBuffer(inner_name='in_out_ptr1', other_names=['buf5', 'buf7', 'buf9']), 'buf7': InplacedBuffer(inner_name='in_out_ptr1', other_names=['buf5', 'buf7', 'buf9']), 'buf9': InplacedBuffer(inner_name='in_out_ptr1', other_names=['buf5', 'buf7', 'buf9']), 'buf12': InplacedBuffer(inner_name='in_out_ptr2', other_names=['buf12', 'buf13']), 'buf13': InplacedBuffer(inner_name='in_out_ptr2', other_names=['buf12', 'buf13']), 'buf17': InplacedBuffer(inner_name='in_out_ptr3', other_names=['buf17', 'buf19']), 'buf19': InplacedBuffer(inner_name='in_out_ptr3', other_names=['buf17', 'buf19']), 'buf21': InplacedBuffer(inner_name='in_out_ptr4', other_names=['buf21', 'buf25']), 'buf25': InplacedBuffer(inner_name='in_out_ptr4', other_names=['buf21', 'buf25']), 'buf20': InplacedBuffer(inner_name='in_out_ptr5', other_names=['buf20', 'buf26', 'buf31', 'buf32']), 'buf26': InplacedBuffer(inner_name='in_out_ptr5', other_names=['buf20', 'buf26', 'buf31', 'buf32']), 'buf31': InplacedBuffer(inner_name='in_out_ptr5', other_names=['buf20', 'buf26', 'buf31', 'buf32']), 'buf32': InplacedBuffer(inner_name='in_out_ptr5', other_names=['buf20', 'buf26', 'buf31', 'buf32'])} ``` After removing some inplace buffers, the ```self.inplace_buffers``` may be like: ``` {'buf0': InplacedBuffer(inner_name='in_out_ptr0', other_names=['buf0', 'buf2', 'buf4']), 'buf2': InplacedBuffer(inner_name='in_out_ptr0', other_names=['buf0', 'buf2', 'buf4']), 'buf4': InplacedBuffer(inner_name='in_out_ptr0', other_names=['buf0', 'buf2', 'buf4']), 'buf5': 'REMOVED', 'buf7': 'REMOVED', 'buf9': 'REMOVED', 'buf12': 'REMOVED', 'buf13': 'REMOVED', 'buf17': InplacedBuffer(inner_name='in_out_ptr3', other_names=['buf17', 'buf19']), 'buf19': InplacedBuffer(inner_name='in_out_ptr3', other_names=['buf17', 'buf19']), 'buf21': 'REMOVED', 'buf25': 'REMOVED', 'buf20': 'REMOVED', 'buf26': 'REMOVED', 'buf31': 'REMOVED', 'buf32': 'REMOVED', 'buf16': InplacedBuffer(inner_name='in_out_ptr6', other_names=['buf16', 'buf38']), 'buf38': InplacedBuffer(inner_name='in_out_ptr6', other_names=['buf16', 'buf38'])} ``` And then if we mark some buffer as inplace buffer and the buffer name will use ```in_out_ptr{len(unique(self.inplace_buffers.values()))}```, the buffer name may be ```in_out_ptr6``` even this name has existed in ```self.inplace_buffers```. After this PR, we will change ```REMOVED``` to ```REMOVED{1, 2, 3..}``` which avoids defining a duplicate name. ```pyhpc_equation_of_state ``` of ```torchbench``` will work for CPU backend: ```python -m torch.backends.xeon.run_cpu --node_id 0 benchmarks/dynamo/torchbench.py --performance --inference --float32 -dcpu -n50 --inductor --freezing --no-skip --dashboard --only pyhpc_equation_of_state --cold_start_latency``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/106852 Approved by: https://github.com/lezcano
