Serhiy Storchaka added the comment: Thank you Raymond. Committed without the prediction from DUP_TOP_TWO to BINARY_SUBSCR.
What are you think about following highly predictive pairs? 1. From UNPACK_SEQUENCE to STORE_FAST with 96.5% probability. This is the 15th of most common pairs. It is more common than any other predicted pairs except the COMPARE_OP/POP_JUMP_IF_FALSE pair. I suppose it is mostly used in for loops over dict.items(), enumerate(), etc. I suppose the remaining 3.5% are unpacking to object attributes (like "self.x, self.y = ..."). 2. From BUILD_SLICE to BINARY_SUBSCR with 99.3% probability. This is the 37th of most common pairs. It is more common than any other predicted pairs except the three most common pairs. The remaining 0.7% are slice assignment (0.42%), slice deleting (0.29%), slice inplace operations and extended slices. FYI here is a list of most common pairs (predicted pairs are starred). 1. 5.84% LOAD_FAST LOAD_FAST 22.6% 2. 5.16% LOAD_FAST LOAD_ATTR 20.0% 3. 4.18% COMPARE_OP POP_JUMP_IF_FALSE 82.9% * 4. 3.97% POP_JUMP_IF_FALSE LOAD_FAST 66.3% 5. 3.90% STORE_FAST LOAD_FAST 47.2% 6. 3.70% LOAD_FAST CALL_FUNCTION 14.3% 7. 3.36% LOAD_FAST LOAD_CONST 13.0% 8. 2.64% LOAD_ATTR LOAD_FAST 35.2% 9. 2.28% LOAD_CONST COMPARE_OP 26.7% 10. 2.12% STORE_FAST STORE_FAST 25.6% 11. 2.09% LOAD_GLOBAL LOAD_FAST 37.5% 12. 1.49% CALL_FUNCTION STORE_FAST 20.5% 13. 1.44% <0> LOAD_FAST 39.1% 14. 1.37% JUMP_ABSOLUTE FOR_ITER 77.6% 15. 1.29% UNPACK_SEQUENCE STORE_FAST 96.5% 16. 1.28% CALL_FUNCTION POP_TOP 17.7% 17. 1.28% LOAD_FAST LOAD_GLOBAL 4.9% 18. 1.26% FOR_ITER STORE_FAST 50.3% * 19. 1.25% LOAD_CONST RETURN_VALUE 14.6% 20. 1.19% LOAD_ATTR LOAD_CONST 15.9% ... 36. 0.65% COMPARE_OP POP_JUMP_IF_TRUE 13.0% * 37. 0.65% BUILD_SLICE BINARY_SUBSCR 99.3% ... 45. 0.55% SETUP_LOOP LOAD_FAST 80.7% 46. 0.55% GET_ITER FOR_ITER 71.9% * 47. 0.53% FOR_ITER UNPACK_SEQUENCE 21.2% * ... 50. 0.50% FOR_ITER POP_BLOCK 20.0% * ... 66. 0.33% ROT_TWO STORE_FAST 85.8% ... 71. 0.31% INPLACE_ADD STORE_FAST 92.1% ... 73. 0.30% LIST_APPEND JUMP_ABSOLUTE 100.0% * ... 90. 0.22% BUILD_MAP STORE_FAST 85.3% ... 93. 0.21% GET_ITER CALL_FUNCTION 28.1% * ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27255> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
