Hi Tim, Thank you for clarifying what the error actually means! I did read something about the BLX instruction but since I'm compiling strictly for thumb, it didn't make much sense to me. Adding -mdisable-tail-calls as a cc1 command indeed allowed me to link the generated binary. After looking some more at the ld64 source code, I came across the following comment: // The tail-call optimization may result in a function ending in a jump (b) // to another functions. At compile time the compiler doe...
