URL: http://llvm.org/viewvc/llvm-project?rev=346520&view=rev
Log:
Use the correct address space when emitting the ctor function list
This patch modifies clang so that, if compiling for a target that
explicitly specifies a nonzero program memory address space, the
constructor list global will have the same address space as the
functions it contains.
AVR is the only in-tree backend which has a nonzero program memory
address space.
Without this, the IR verifier would always fail if a constructor
was used on a Harvard architecture backend.
This has no functional change to any in-tree backends except AVR.
