In this forum post, we can read some interesting comments by Michael Swindell from Embarcadero:
Re FPC, we will be coming out with a Delphi ARM compiler at some point, but we’re appreciative that FPC is available today for ARM/iOS and we were able to leverage to get FireMonkey to iOS.
So it’s just a stopgap solution for them until they have time to build their own ARM compiler, but the fact that they will ship FPC definitely serves as a testament to its quality Very cool!
So FireMonkey will use the FreePacal compiler for iOS in XE2. But this will be a interim solution. For me the big test will come when Embarcadero releases it’s first none Intel x86 compiler. This will be the acid test as to whether they have snuff to really do cross compiler solutions (and I certainly hope they make the grade).
