Class AssignMulti

mypyc/ir/ops.py:351–381

Assign multiple values to a Register (dest = src1, src2, ...). This is used to initialize RArray values. It's provided to avoid very verbose IR for common vectorcall operations. Note that this interacts atypically with reference counting. We assume that each RArray register is init
