Coming soon: second generation prototype of Hg forest consolidation

[Stefan Karlsson]

Hi all,

Great to see that the consolidation work is going forward!

I have comment specific to the HotSpot code layout:

We previously had this layout (using a small set of directories as an 
example):
  hotspot/src/share/vm
  hotspot/src/os/linux/vm
  hotspot/src/os/solaris/vm
  hotspot/src/os/solaris/dtrace
  hotspot/src/os/bsd/launcher
  hotspot/src/share/tools/hsdis

and this is the new layout:
  src/hotspot/share/vm
  src/hotspot/os/linux/vm
  src/hotspot/os/solaris/vm
  src/hotspot/os/solaris/dtrace
  src/hotspot/os/bsd/launcher
  src/hotspot/share/tools/hsdis

should we consider changing the layout of the HotSpot code so that we 
don't mix the source code for the vm, tools, launcher? For example:
  src/hotspot/vm/share
  src/hotspot/vm/os/linux
  src/hotspot/vm/os/solaris
  src/hotspot/launcher/os/bsd
  src/hotspot/tools/hsdis
  src/hotspot/dtrace/os/solaris

I'm not sure that we would want to include such a change in the 
consolidation effort, but we are changing all file paths so maybe it's 
the right time to think about this.

Cheers,
StefanK
