Re: RFC: [GUPC] UPC-related front-end changes

[Gary Funck]

Off list, Mike S. pointed out that the Objective C
front-end uses the lang-specific extensions to
GCC's tree node, and it shares logic with the C
and C++ front ends.  Therefore, the lang-specific
extensions might offer an alternative approach
for storing UPC's layout qualifier.  The current plan,
however, is to use a hash table.
