Description Jeff Sturm 2002-08-27 14:26:01 UTC

Consider turning -findirect-dispatch on by default.  It solves some serious problems with compatibility of classes, e.g. adding/removing methods or changing method order.

The obvious drawback is decreased performance.  However some studies have shown the impact to be minimal, and -fno-indirect-dispatch can get the old behavior.

Release:
3.4?

Jeff, what's the status of this? Do you have a testcase exhibiting the problematic behavior? Thanks,

Dara

Comment 2 Andrew Pinski 2003-07-24 11:52:27 UTC

still true (-findirect-dispatch is enabled by default) on the mainline (20030724).

Waaaait.  This bug is that -findirect-dispatch was *off* by default and should
have been *on*.  If -findirect-dispatch is enabled by default in the mainline,
then the bug is *fixed*.

Andrew?  Could you clarify?  Did you get confused about the nature of the bug,
or did you accidentally omit the word 'not'?

Comment 4 Andrew Pinski 2003-08-03 17:42:23 UTC

I missed the word not. woops.

Comment 5 Andrew Pinski 2016-09-30 22:50:35 UTC

Closing as won't fix as the Java front-end has been removed from the trunk.
