llvm dev - Dec 2015 - Fwd: getting started changing the emitted code: at one instruction at function top

I'm just getting started changing the emitted code.  Suppose I want to
just add one new instruction to the function prologue at the top.
Where would I do this?  Does it depend on the backend?  I'm targeting
RISCV64.

Hi Gry,

Yes, this depends on the backend. You'll want to look at your backend's
*FrameLowering::emitPrologue function (in lib/Target/*/*FrameLowering.cpp).

I can't use svn to check out anything and I notice all the buildbots are 
failing.  As they finish up their current runs they then fail when 
trying to start a new one and are unable to connect to llvm.org.
