<pre>lib/Target/ARM/ARMFastISel.cpp:ARM::createFastISel enables FastISel in the
following circumstances:
bool UseFastISel = false;
UseFastISel |= Subtarget->isTargetIOS() && !Subtarget->isThumb1Only();
UseFastISel |= Subtarget->isTargetLinux() && !Subtarget->isThumb();
UseFastISel |= Subtarget->isTargetNaCl() && !Subtarget->isThumb();
Thumb2 FastISel has issues with at least some relocations as well as with MI
validation, but should otherwise be able to use FastISel.</pre>
