...constraint through the operands from the DAG. There would need to be some way to specify that the SDOperand is referencing a subvalue of the produced value (perhaps a subclass of SDOperand?). This would allow the register allocator to try to use the sub/super register sets to perform the instert/extract. Is any of this kind of work planned? The addition of those MRegisterInfo functions has me curious... -- Christopher Lamb

...t I like.* Hence, I do not want to use any in this case. I think that allowing to assing NULL to a slot will solve some problems which I have with S4 so far. a) How to express that an a slot content was not assigned so far? J.C. suggest to use character(0), lm(1~1) etc. The problem I have with insterting lm(1~1) in slot mod in my class Ctest are that I have 100000 instances of object Ctest. At initialization everyone contains an object lm(1~1). But please note the following. > x<-lm(1~1) > object.size(x) [1] 6388 > object.size(NULL) [1] 0 Unfortunately S4 do not have referenc...

Evan is currently focusing on getting the late stages of the code generator (e.g. livevars) to be able to understand arbitrary machine instrs in the face of physreg subregs. This lays the groundwork for handling vreg subregs, but won't solve it directly. > Is any of th...

I''m trying desperately to get visuall effects callbacks working in rjs templates to no avail What I''m trying to do is fade an image, change the div with the image to a new image, and then fade the new image back in. How would I go about this in RJS Here''s a simple line from my rjs that I can''t get to work. It is not using callbacks so the

My housemate has formalized a sortof new attack against unix-style operating systems. He''s a BSD fan, so that''s where he developed the attack. He asked me to check Linux, which I did. It seems Linux is not vulnerable to it. This attack is going out to BUGTRAQ tonight. The attack isn''t too serious because it requires physical access to the console, but it
