TASKING VX-toolset for ARM User Guide

TASKING VX-toolset for ARM User GuideC++ compiler option: --cpu (-C)Menu entry1. Expand C/C++ Build and select Processor.2. From the Processor Selection list, make a selection by Architecture, Core or one of themanufacturers.Command line syntax--cpu=architecture-CarchitectureYou can specify the following architectures:ARMv6MARMv7MARMv7EMARMv7RCompile for ARMv6-M architectureCompile for ARMv7-M architectureCompile for ARMv7E-M architectureCompile for ARMv7-R architectureDescriptionWith this option you specify the ARM architecture for which you create your application. The ARM targetsupports more than one architecture and therefore you need to specify for which architecture the compilershould compile. The architecture determines which instructions are valid and which are not.The effect of this option is that the C++ compiler uses the appropriate instruction set. You choose one ofthe following architectures: ARMv6-M, ARMv7-M, ARMv7E-M or ARMv7-R.The macro __CPU__ is set to the name of the architecture.ExampleTo compile the file test.cc for the ARMv7E-M architecture, enter the following on the command line:cparm --cpu=ARMv7EM test.ccRelated informationC compiler option --cpu (Select architecture)378
