Assembly File Creation From C Source File

Hi, I am Practicing Assembly Language Programming for ARM7TDMI Architecture.
I want to generate the Assembly Source code File for my input C source File
(Like Listing File Generation).Is it Possible in Keil.If yes mean,What all
are the configuration i have to do in target option Tab.

Thanks in Advance,

  • Use the Options -> Listing tab, check the "Assembler Listing" box, although this does not work in the eval release as I recall.

  • Thanks for your Reply...

    But Sorry I cant Get your words exactly.

    My Doubt was,

    Let Take the input file as below.

    Main.c
    ==========
    /************ start of file ************/
    void main()
    { Statement1; Statement2; Statement3; Function1(); Function2();
    }

    Function1()
    { Statement1; Statement2;
    }

    Function2()
    { Statement1; Statement2;
    } /*********** End of File ***************/

    Just Take Main.C as input File.while we build this project this will generate hex file.
    Here i want the asm file(main.asm) equivalent to the main.c.while debugging this program the disassembly section allow as to see the asm file equivalent to c file.But i want the asm file separately in my project folder. Is it possible?

    Thanks and Regards,
    Shanmugam.S

    QUESTION
    How do I create an assembler file from my C source file?

    ANSWER
    Use the --asm control to create assembler output from the C compiler. The --asm control causes the compiler to generate an .S file with the same name as your C file. You may then assemble the .S file with the assembler.

    The --asm control is entered in µVision under Project — Options — C/C++ tab, Misc Controls. Also disable the option Project — Listing — C Compiler Listing since this uses a different output.

    The Assembly file will have a .ASM extension, and will be in your listing file folder for your project.

    =====================================================================================

    i have used the above mentioned setting in keil for generating the asm source file from c source file but it generating the error given below

    Unrecognized option -S or --asm error


  • Do you have a paid-for, licensed version of the tools?

  • I think that is evaluation version.Sorry u already told that it ll not work in the evaluation version. what is the other possibilities avail to do this one????
    In order to buy the licensed version what i have to do???

    Simple thing i need is i want the asm equivalent to the c file.
