(The previous sent message had some issues...) ---------------------------------------------- Hello to everybody, I just want make a quick summary: OBJECTIVE: discuss for finding a way to represent logical (derived from source language abstractions) address space also in the IR to be able to exploit this information for optimizations. CURRENT STATE: The partial workaround probably used IMO

...is thread: * different sized address regs * most address regs are larger than int regs * address regs only support a sub-set of operations * some address spaces are disjoint, some may overlap. so far, I declared a data layout with "-p0:xx:yy-pp1:zz:aa-p2:... " etc. ... implemented getPointerWidthV() (and getPointerRegClass(), which never seems to get called). I see that global data items are correctly sized according to my pointer definitions - but that all operations are carried out as if pointers were sized for address space 0. What is required to (at minimum) get the different size poin...

Hello to everybody, I would like to start a discussion about a possible extension of address space concept in LLVM. The idea was born starting from this discussion in the clang mailing list (first msg: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130715/084011.html - interesting point: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130722/084499.html) where
