LIST-File on CW5.1

[Truk]

I try to setup CW5.1 to make a .LST file but I could not find where I could do this. The HELP tell me to add the -L option but where can I do this? I have only the MAKE button which does all, but I can't find the file behind this button to modify nor menue where I could setup the Make file.

thanks for any help

The listing file is generated by the assembler. If you're using the IDE, go to the project's Preferences panel (Edit | YourProjectNameHere Settings...) and choose the Assembler panel. You might be presented with a command line in which case, try:

-L=%(TEXTPATH)\%n.lst

Or, if there's a GUI, try checkboxing the item, Generate a Listing File.

I too am trying to get the assembler to produce a listing file.

I went to the Edit->YourProjectNameHere Settings and using the GUI, I select Target Settings Panel->ColdFire Assembler but the Generate Listing File checkbox is grayed out!

Is this a limitation of the special edition version of CodeWarrior for ColdFire V6.3 build 14 or simply a bug?

Hello

For CodeWarrior for Coldfire to get a listing file for a specific source file:

  - Select the source file in the .mcp window
  - Click on it with the right mouse button
  - Select Disassemble from the drop down menu.

A new editor window should show up showing the disassembly listing.

You can adjust the content of the listing file using the "ELF Disassembler" panel.

I hope this help.

hmmm...

I've looked at the disassembly function but it doesn't produce a standard assembly listing file.

Is there any way to invoke the assembler from a command line and, if so,  are there other options  available?

Hello

I do not know what you call a "standard assembly listing file"? Can you tell me what you expect.

Anyway, you can produce a disassembly listing file using the command line compiler and specifying option

-dis.

The command line compiler can be found in {Install}\E68K_Tools\Command_Line_Tools and is called mwccmcf.exe.

I am afraid this will probably generate the same disassembly listing as the disassemble menu.

There is no separate tool available to disassemble an object file.

The above is an example of assembly code, listing file and disassembly.  Note that the disassembly loses the source comments and operand labeling, making it less than useful.

I gather that not too many of your users have as much legacy code written in assembler as I have.  I need to carry this old code up into an environment supporting the c, c++, ethernet stacks, etc.  I'm sure I'll be porting this legacy code over time as needed, but for now, if it ain't broke....

Thanks anyways,

Scott

Hello

You will not get exactly the output you are use to.
But if in the ELF disassembler panel you make sure "Show Source Code" and "Show Comments" are checked you get something as follows, which at least provides you with the comments and labels from the original source file.

Code:

Note that I get that with CodeWarrior Coldfire V6.x. I am not sure CodeWarrior for Coldfire V5.x has the same options available in the ELF Disassembler panel.
