+ This test documents the source pointer address conversion methods for StandardSourceFileArray.
+ 
+ The available address space for source pointers in CompiledMethod is 16r1000000 through 16r4FFFFFF. StandardSourceFileArray maps positions in the sources file to address range 16r1000000 through 16r1FFFFFF and 16r3000000 through 16r3FFFFFF, and positions in the changes file to address range 16r2000000 through 16r2FFFFFF and 16r4000000 through 16r4FFFFFF. This permits a maximum file size of 16r2000000 (32MB) for both the sources file and the changes file.
