The most difficult part of adding LLVM to the build of a project + is to determine the set of LLVM libraries corresponding to the set + of required LLVM features. What follows is an example of how to + obtain this information:

+ +
+ 
+    # A convenience variable:
+    set(LLVM_ROOT "" CACHE PATH "Root of LLVM install.")
+    # A bit of a sanity check:

+    include(LLVM)
+    # Now set the header and library paths:
+    include_directories( ${LLVM_ROOT}/include )
+    link_directories( ${LLVM_ROOT}/lib )
+    # Let's suppose we want to build a JIT compiler with support for

+    # Finally, we link the LLVM libraries to our executable:
+    target_link_libraries(mycompiler ${REQ_LLVM_LIBRARIES})
+
+
+ +

This assumes that LLVM_ROOT points to an install of LLVM. The + procedure works too for uninstalled builds although we need to take + care to add an include_directories for the location of the + headers on the LLVM source directory (if we are building + out-of-source.)

      Overview:
      
-
      A union type describes an object with size and alignment suitable for
-   an object of any one of a given set of types (also known as an "untagged"
-   union). It is similar in concept and usage to a
-   struct, except that all members of the union
-   have an offset of zero. The elements of a union may be any type that has a
-   size. Unions must have at least one member - empty unions are not allowed.
-   
      
-
-
      The size of the union as a whole will be the size of its largest member,
-   and the alignment requirements of the union as a whole will be the largest
-   alignment requirement of any member.
      
-
-
      Union members are accessed using 'load and
-   'store' by getting a pointer to a field with
-   the 'getelementptr' instruction.
-   Since all members are at offset zero, the getelementptr instruction does
-   not affect the address, only the type of the resulting pointer.
