&gt; I was wondering why this never posed a problem before for us before.  I did
&gt; a local build, and see that the compiled LowLevelInterpreter.o does emit blx
&gt; instructions.  However, in the llinked version of the code, the linker
&gt; changed the blx into bl instructions.  If the toolchain does not fix this
&gt; for us, then this bug would have manifested.</span >

It's right to use blx on iOS.
