[LLVMdev] Register based vector insert/extract
...ers()/getSuperRegisters() to
MRegisterInfo. This is what's needed in order to implement the
register allocation constraint, but there's no way yet to pass the
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...

Right. Evan is currently focusing on getting the late stages of the code
generator (e.g. livevars) to be able...

[LLVMdev] running clang format on the Mips target
Hi David,
I agree with you that it would be rude to simply clang-format the MIPS backend without coordination with any out-of-tree derivatives. To be honest, it hadn't occurred to me that there would be any such derivatives and the possibility wasn't raised in our internal discussion before we brought the subject up on this list. I'm keen to coordinate with such derivatives to

Bridging R to OpenOffice
Dear members of the R Development Team,
I am looking for people with a deep understanding of R internals to
assist in bridging R to OpenOffice.
While R is a state of the art statistical environment, less experienced
users often find it difficult to work with R. Therefore, I believe that
a bridge between R and a spreadsheet program will make this transition
less painful. I sincerely believe
