4.5.6 Command-Line Options

Besides the switches common to all SDCC backends, the PIC14 port accepts the following options (for an updated list see sdcc --help):

--debug-xtra
emit debug info in assembly output
--no-pcode-opt
disable (slightly faulty) optimization on pCode
--stack-loc
sets the lowest address of the argument passing stack (defaults to a suitably large shared databank to reduce BANKSEL overhead)
--stack-size
sets the size if the argument passing stack (default: 16, minimum: 4)
--use-non-free
make non-free device headers and libraries available in the compiler's search paths (implicit -I and -L options)
--no-extended-instructions
forbid use of the extended instruction set (e.g., ADDFSR)
