TASKING VX-toolset for ARM User Guide

Tool OptionsControl program 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 | processor-Carchitecture | processorYou can specify the following architectures:ARMv6MARMv7MARMv7EMARMv7RCompile/assemble for ARMv6-M architectureCompile/assemble for ARMv7-M architectureCompile/assemble for ARMv7E-M architectureCompile/assemble for ARMv7-R architectureDescriptionWith this option you specify the ARM architecture for which you create your application. The architecturedetermines which instructions are valid and which are not. The default architecture is ARMv7M and thecomplete list of supported architectures is: ARMv6-M, ARMv7-M, ARMv7E-M or ARMv7-R. Instead ofthe architecture name you can also specify the full processor name, like "STM32F205RB".The standard list of supported processors is defined in the file processors.xml. This file defines foreach processor its full name (for example, STM32F205RB), its ID (for example, stm32f205rb), thearchitecture name (for example, ARMv7M), the core settings (for example, cortexm3), the on-chip flashsettings, the list of silicon bugs for that processor. Each processor also defines options to supply to thelinker for preprocessing the LSL file for the applicable on-chip memory definitions (for example,-D__FLASH_SIZE=128k).The control program reads the file processors.xml. The lookup sequence for names specified to thisoption is as follows:1. match any of the standard architecture names (as listed above, for example ARMv7M)2. if none matched, match with the 'id' attribute in processors.xml (case insensitive, for examplearmv7_m)3. if still none matched, match with the 'name' attribute in processors.xml (case insensitive, for exampleSTM32F205RB)4. if still none matched, the control program issues a fatal error.591
