ARM Instructions Viewer

Hello

I was wondering what software program can help me translate a C/C++ code program to the corresponding set of ARM instructions. I DO care about browsing the ARM instructions.
Does RVDS4.1 serve this purpose, or it doesn't enable viewing the instructions? and any idea about the unsupported features of RVDS 4.1 evaluation product?

Thanks in advance

    When you compile C/C++ files you can tell the compiler to generate an assembler listing as well as an object.  Just add "--asm" to the command.  For example:

      armcc --debug --cpu=ARM926EJ-S -O2 -c --asm my_code.c

    Assuming no compile errors, you see my_code.o and my_code.s generated.  The my_code.s file has the assembler listing.

    You can do pretty much the same thing post compile, or for a complete image, using the fromelf tool.  Just run:

      fromelf -c my_object.o/my_image.axf

    The output gets dumped to the console, so you probably want to re-direct it the a file. 

    The main difference between the two approaches is the output format.  The file generated by the compiler (something.s) can be run through the assembler (armasm) to generate an object.  The output of fromelf cannot.
