Allow automatic switching of load address #33

Open Brett208 opened 5 years ago

Brett208 commented 5 years ago

Is there a way to automatically switch between the 2 load addresses? I have to keep being very careful about what I commit in the .asm file and probably accidently commited the change recently. It would just ease some admin burden on my part.

Would a MACRO that was definable from NetFixClient or something work for this.

Thanks, Brett

You're quite right. That would be a very nice problem to solve.

I'm not currently sure how, but it seems NASM supports Conditional Assembly (section 4.4). That may allow usage similar to how some C++ code conditionally defines either __declspec(dllexport) or __declspec(dllimport). However, in those C++ projects, the macro is set in the project file of the project itself, rather than the project that imports it.

The NASM -d command line option can be used to pre-define a macro.

Alternatively, the NASM -p command line option can be used to pre-include a file.

Those might both be a way of defining an alternative address.

How to control this from the host project is unclear though.

The other option, is to hurry up and find a way to replace the assembly file with another method. That would also eliminate this burden.
