Comment #2 on issue 636 by [email protected]: String handling broken
(test case)
http://code.google.com/p/v8/issues/detail?id=636
Original report obviously contains a typo: simple arithmetic shows that
10000000001 is correct result (2^10 +
2^0 == 1025), while 01000000001 is incorrect result (2^9 + 2^0 != 1025).
So bug is reproducible on ia32 and not reproducible on x64.
And indeed it is related to the code I am currently ported. As Sørren
forseen in his review of my changes there is
a bug in string+smi case optimization on ia32. Current code does not
respect HashArgsReversed() == true case,
so concatenation smi+string is reversed into string+smi.
