TASKING VX-toolset for ARM User Guide

TASKING VX-toolset for ARM User GuideIf you specify a full processor name (or its ID), the control program passes the option -D__PROC_id __to C compiler and the linker. id is the 'id' attribute belonging to the processor found in processors.xml,in uppercase. The control program also passes the macros defined with the 'linker_macros' propertyof the processor found in the processors.xml to the linker (for example,-D__DEVICE_LSL_FILE=stm32f2xx.lsl).Assembly code can check the value of the option by means of the built-in function @CPU(). ArchitectureARMv7-M only supports the Thumb-2 instruction set, i.e. it has no ARM execution state.ExampleAfterccarm --cpu="STM32F205RB" -v -t test.cthe control program will call the tools as follows:carm -CARMv7M -D__PROC_STM32F205RB__ -o test.src test.casarmt -CARMv7M -o test.obj test.srclkarm test.obj -o test.abs -CARMv7M -D__PROC_STM32F205RB__-D__DEVICE_LSL_FILE=stm32f2xx.lsl -D__FLASH_SIZE=128k -D__SRAM_SIZE=64k--map-file -lcthumb -lfpthumb -lrtthumbRelated informationControl program option --cpu-list (Show list of processors)C compiler option --cpu (Select architecture)Assembler option --cpu (Select architecture)Control program option --processors (Read additional processor definitions)Control program option --tasking-sfr (Include CMSIS SFR file)Assembly function @CPU()592
