It is related to #1855. When I checked it with jerry-test-suite and jerry-tests, there was no regression. And when I run benchmarks 10kk, and 1kk, it also shows no regression on x86_64. Could you check the correctness and run sunspider? |

The bug must be elsewhere. -0 is not an integer number in JerryScript. I suspect the division is the problem. Let me check. |

There was a problem hiding this comment.
Ok, it is a bug with the multiplication but we need to move this check down to the if starting with:
if (-ECMA_INTEGER_MULTIPLY_MAX <= left_integer
Add:
&& left_integer != 0
&& right_integer != 0

Ok. I'll move it. Thank you for review. |
Keep sign for zero. For example, 1 / (0 * (-1)) should be -Infinity, not +Infinity. JerryScript-DCO-1.0-Signed-off-by: Sanggyu Lee sg5.lee@samsung.com
