GNU ld version 2.16.1, compiled as arm-elf-ld for Darwin/OS X: called with
"-Map filename.map", ld
produces memory map text (listed under "Linker script and memory map") that is
ordered neither
alphabetically by symbol nor sequentially by absolute location, although
entries are grouped together
by .o object file. Lack of ordering makes the memory map much more difficult
to use as an index,
which I believe is the intended application.
I spent two hours looking at ld/ldlang.c and bfd/linker.c but could not even
figure out where exactly
each address/symbol pair is added to the for-printing statement list, much less
where the sorting (or
lack thereof) is taking place and how one might introduce a sorting algorithm.
This is not a bug, but it is not a feature either. I can't find any other
mention of this problem which
makes me wonder if perhaps I am misusing ld. I would think this behavior would
annoy just about
everyone.
Thanks, --Bill
