            Bug ID: 31568
           Summary: [AVR] Support the '__flash' attribute
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P

          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

Support for the '__flash' keyword will need to be added in order to place data
into program memory.

The parser will need to be modified to understand the keyword and then place
data into the progmem address space.

Examples of LLVM IR placing variables in the program memory can be found in
'test/CodeGen/AVR/progmem.ll' in LLVM.
