[LLVMdev] Questions about instruction selection and instruction definitions
...2_ regs. This is not quite obvious for me why this
classes are introduced at all, if they are almost not used anywhere in
the descriptions ...
On my target, there are many instructions that have certain constraints
using register subclasses, for example:
loads from memory are only allowed to the GR_ regs
copies between GR and GR_ regs are allowed
stores to memory are only possible from GR_ regs
How this can be expressed in the definitions of instructions? I tried
to use GR_ register classes at appropriate places, when describing
instructions operands. Is it a right method? So far I was n...

About regression and plot
Dear R-help,
This is my first R day. I want to ask some more beginner's questions.
Q1. How can I obtain the covariance matrix for parameter estimates of a multiple regression? I checked ?lm but didn't get the information.
Q2. How can I see the old graphs in the graph window?
Q3. Can R plot animated graph? For example, I want to see the dynamic change of a 2D graph during a time
