Bug 30516 - Shift more than 32 bits dosent work on a long

[Juan Rolando Prieur-Reza]

This bug is still present in Java 8 and bugzilla says there is no one assigned to fix it. Originally posted in 2007.
Is there any way to put this "major" bug into Oracle's priority list for fixes?

Note that the bug description https://gcc.gnu.org/bugzilla/show_bug.cgi?id=30516
does not fully define the defective variations on 64-bit shift and compare operations. They are acting as if they are partially on a 32 bit machine running 32 bit Java.

Is there a patch in the works?

"major" bug?

[Stefan Evans]

Two things

1: The bug has been marked as "RESOLVED INVALID". That would indicate that it is not a bug. Read the comments on it.
2: You've linked a bug from GCC - the C Compiler. That ain't Java.

My guess is that there is no bug, hence no patch. And it has nothing to do with Java anyway, let alone Java 8

[Henry Wong]

Agreed. Can you explain how an *invalid* bug that was reported with the gcc c compiler have anything to do with Java 8? It is an invalid bug. It is for a different language. etc. etc.


BTW, I just bit shifted a long variable of value one, thirty three times to the left (as in the signed part of the example). The printed result is correct.
