...set the optimization level of a single function?

I have a source file that contains a number of functions and I want to set the optimization level of one of those functions to a different value. Is it possible to set the optimization level of a single function within a single source file?

 

No, the optimization level can only be set for the entire source file using the Compiler > Optimization Level project property. You will need to put the function into another source file and set the optimization level of this source file to the required value.

  Is this for V2 Cross Studio? I'm using version 2.0.8 of Cross Studio for MSP430. There is no Compiler > Optimization level that I can find (doesn't mean it doesn't exist of course), although the compiler compiles the file I am interested in with -O+9 (max speed). How do I turn off the optimisation for 1 file? And how does the optimisation level number relate to the project code generation options (if at all?)

  The optimization level is set for the linker, higher numbers get more optimizations applied.  Individual optimizations are documented.

  The MSP430 CrossWorks does not offer per-file optimization, only whole-program optimization.
