> Hmm. Does the gnu.linkonce trick work for shared libraries?
Yes, it does:
mira% g++ -c -fPIC -ftemplate-depth-110 a.cc
mira% size a.o
text data bss dec hex filename
128446 9656 1 138103 21b77 a.o
mira% g++ -c -fPIC -ftemplate-depth-110 b.cc
mira% size a.o
text data bss dec hex filename
128446 9656 1 138103 21b77 a.o
mira% g++ -shared -o a.so a.o b.o
mira% size a.so
text data bss dec hex filename
153487 20756 32 174275 2a8c3 a.so
What doesn't work: you can't eliminate template instantiations from a
shared library in the final link of the program.
