Hi,
:I am working on speeding up nm -l in the case a large binary. I
added a bit of code that uses the BFD hash table in dwarf2.c. The
speed comes with a price in terms of memory usage. However, I found
that I can reduce the extra memory required significantly if I do not
copy hash keys. My question is whether this is safe. Can I assume that
symbol->name is a constant pointer?
Thanks
-Doug
