Delphi XE2 generates RSM files that are several MB in size. As I
understand it,these files are for remote debugging. Is there a way
to turn off the generation of these files?

Yes. In the Project Options look on the page “Delphi Compiler\Linking”
for “Include remote debug symbols” and turn it off if you do Win32
debugging. Note it is necessary for Win64 debugging.

The IDE is 32-bit,because that’s the only way it can work on both 32
and 64 bit versions of Windows. (Win64 can run 32 bit apps,but Win32
can’t run 64 bit apps.) That’s why the remote debugger is used for 64
bit and cross-platform apps.

Is the reason that Delphi XE2 is not itself really 64-bit?

Sure,then it can’t be run on 32 bit OS’s. All third party components won’t work at all until a 64 bit version of it exists (a 64 bit IDE would not be able to load a 32 bit bpl),this would be a major reason for people not to upgrade too. Supporting both a 32 bit and 64 bit IDE doubles the testing time for little to no benefit.
