When a semihosting request is encountered, RealView ARMulator ISS traps the SVC directly and the instruction in the SVC entry in the vector table is not executed.

To turn the support for semihosting off in RealView ARMulator ISS, change Default_Semihost in the default.ami file to No_Semihost.

See the RealView ARMulator ISS User Guide for more information.
