optimization level execution time code size memory usage compile time-O0: optimization for compilation time (default) + +-O1 or -O: optimization for code size and execution time-+ +-O2: optimization more for code size and execution time- + ++-O3: optimization more for code size and execution time- + +++-Os: optimization for code size - ++-Ofas This presentation looks at optimizations performed by the MPLAB® XC8 C Compiler that might result in unexpected behavior when debugging. It should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable level of optimization while maintaining fast compilation and a.
Og enables optimizations that do not interfere with debugging. O0 (do no optimization, the default if no optimization level is specified)-O1 (optimize minimally)-O2 (optimize more)-O3 (optimize even more)-Ofast (optimize very aggressively to the point of breaking standard compliance)-Og (Optimize debugging experience.

MPLAB XC8 C Compiler 1.41 is available as a free. Use the Pro evaluation version (reverts to free version after 60 days) Microchip MPLAB XC8 C Compiler (PRO Mode) V1.32 XC16 StandardPROOptimization level(). Otherwise, choose to: Purchase a license (to receive an activation key that will unlock the Standard or Pro optimization features). Wish to use the free version of the compiler (some optimization features disabled).

Build your project with the compiler optimization level setting = PRO. xc8-cc -mcpu=18f4520 -Os main.c Oops, you cannot select level 's' optimizations if this compiler is unlicensed The code is compiled with no optimizations and exceeded the memory size of the microcontroller. (2051) The current licence does not permit the selected optimization level* (Driver) This compiler's license does not allow the requested compiler operating mode. Code can become orphaned by other optimizations and cannot be reached during normal execution, e.g., instructions after a return instruction optimization-level MPLAB X IDE Microchi The program that works with optimization has 0, the compiler 1.33 and MPLAB X IDE v2.30 is: C: \ microchip \ harmony \ v1_03_01 \ apps \ tcpip \ web_server_nvm_mpfs This optimization is enabled at optimization level 2, making it accessible to unlicensed compilers.
