TASKING VX-toolset for ARM User GuideC compiler option: --runtime (-r)Menu entry1. Select C/C++ Compiler » Debugging.2. Enable or disable one or more of the following run-time error checking options:• Generate code for bounds checking• Generate code to detect unhandled case in a switch• Generate code for malloc consistency checks• Generate code for stack overflow checks (allowed for USR and SYS mode only)• Generate code for division by zero checksCommand line syntax--runtime[=flag,...]-r[flags]You can set the following flags:+/-bounds+/-case+/-malloc+/-stack+/-zerob/Bc/Cm/Ms/Sz/Zbounds checkingreport unhandled case in a switchmalloc consistency checkscheck for stack overflowcheck for divide by zeroDefault (without flags): -rbcmSZDescriptionThis option controls a number of run-time checks to detect errors during program execution. Some ofthese checks require additional code to be inserted in the generated code, and may therefore slow downthe program execution. The following checks are available:Bounds checkingEvery pointer update and dereference will be checked to detect out-of-bounds accesses, null pointersand uninitialized automatic pointer variables. This check will increase the code size and slow down theprogram considerably. In addition, some heap memory is allocated to store the bounds information. Youmay enable bounds checking for individual modules or even parts of modules only (see #pragmaruntime).352
