The inline assembler accepts standard ARM or Thumb instructions and introduces several special assembler instructions that provide access to C automatic variables and parameters.
- LDAV loads a register with the contents of an automatic variable or function argument.
- STAV stores a register contents to an automatic variable or function argument.
- LDAA loads a register with the address of an automatic variable or function argument.
Note
- These instructions are not valid ARM or Thumb instructions. They are only supported by the inline assembler in the CARM Compiler.
