Generating debug symbols for ROM images

I’ve started to look at how we can modify the build system to generate debug symbols for an entire ROM image. This should help make debugging easier when things inevitably go wrong.

The good news is that it’s quite easy to modify the makefile fragments to allow all C & assembler modules to produce GPA files when compiled into ROM images.

The bad news is that passing -g to cc seems to alter the code it produces, even though the manual makes no mention of this (just that it adds debug tables). Is this something that I’m doing wrong, or are we going to have to resort to using link’s -Symbols option instead?

This is news to us. We’re not really going to be able to say what’s going on there without having a trawl through the compiler source code – not a job for the faint-hearted… :(

When I get home tonight I’ll track down the test case I was using and add the details to the bug tracker.

Thanks for that – we’re doing work on and off on the toolchain at the moment so this sort of thing is just the type of issue that we need to look into.
