Personally, I'm comfortable with moving to a contractual obligation for the escaping uses situation: No pass may capture the address of a (previously-uncaptured) global (even locally) without notifying the AA infrastructure. I can't think of any in-tree pass that does this now, although we might certainly have some in the future. Can you think of any we have now? I'd really like to get the AA pass that Sam Parker has been working on (http://revie...

Hey Scott, There has been quite a lot of research on capture tracking (aka escape analysis) for Java and other dynamic languages. See e.g.: https://wiki.openjdk.java.net/display/HotSpot/EscapeAnalysis http://docs.oracle.com/javase/7/docs/technotes/guides/vm/performance-enhancements-7.html http://dl.acm.org/citation.cfm?doid=320384.320386 Nuno -----Original Message----- From: Scott Egerton via

[1.3.20]-Capture The Mouse Works Great. Suggestions... Hi, I've been crying for a long time about mouse issues while running a full screen game in an emulated desktop window, but with newest Wine these issues are gone. Would it be possible to have some hot key that the user can press to uncapture the mouse? For example, VirtualBox toggles mouse capture by pressing the right [Ctrl] key on the keyboard. Thanks again for fixing the mouse, there are many more games I can play now. Jesse

...this is done there is no witness to the internal heap limit variable. 3. Progressive application of dead variable elimination will then delete the entire chain of updates to the heap limit variable, eliminating the side effects that would normally be induced by malloc(). They will also delete the uncaptured pointer result from malloc(). 4. Since the result pointer is not captured, and the heap limit variable is not consulted, the entire result of the call to malloc() is the return of a non-NULL pointer. 5. Constant folding then reduces the IF condition (malloc() == NULL) to false. 6. Dead code eli...

Ok folks, I wrote up the general high-level thoughts I have about stateful AA in a separate thread. But we need to sort out the completely and horribly broken aspects of GlobalsModRef today, and the practical steps forward. This email is totally about the practical stuff. Now, as to why I emailed this group of people and with this subject, the only pass pipeline that includes GlobalsModRef, is
