C51 returns the following error:
*** ERROR C249: 'DATA': SEGMENT TOO LARGE
Rather than switching to the COMPACT or LARGE memory model I would like to manually declare some variables into xdata. I would however like to know what the compiler is actually putting in the data segment and what is taking up the most space. Is there some way I can get this information in the absence of the .MAP file?
Thanks,

Make the DATA segment temporarily bigger - is that even possible (architecture defined) if so how?
Depends what "too large" means in this context. If it's smaller than architecturally limited then make it bigger, if it's already at the limit then try redirecting 'data' into larger segments that can accommodate it. It was a general suggestion about how to look at the problem if the .MAP was the only way to consider how the compiler/linker were behaving.
You're never going to get 2 gallons of crap in a 1 gallon bucket, so if it's architecturally defined to have less capacity than the source needs, someone writing the source needs to actually think about that when coding it.
What's the floor plan for the code/data on the platform you took the code from?
