I've read the F manuals and I'm still no wiser... anyone know how I can get a memory usage listing from gcc (I'm using msp430-gcc)? I've tried
-fmem-report, doesn't not do nowt.

How about the "size" command? Or you can get detailed listings with objdump. Both of these operate on the compiled object files.

You can get a map from the Linker: is that what you mean by a "usage listing"?

Generally you can't --- because it's not the job of gcc to decide about memory usage. That's done by the linker. Get a map file, and/or run 'size' or 'objdump' on the resulting files.

If you're looking for assembly listings try adding
-Wa,-ahlms=myfile.lst
to the gcc compilation command line.
If you're looking for the big picture after linking, get a linker map by adding
-Wl,-Map=myfile.map,--cref
to the gcc command line performing the final link.
If the module cross-reference produces too much output, use the simpler form
-Wl,-Map=myfile.map
Please do not put any extra spaces in the switches or they will be misunderstood by the toolchain.
