I have several questions for the best way to use Interprocedural Program Optimization (IPO) on a DLL or lib. The libraries are big enough that there are good opportunities for IPO.
Right now, I use /Qipo in the compile command line and the link line. The compile line also contains /G7 /O3 /QxW. However, I end up getting link error's about missing symbol: __vmlSin4. Now I know this is from the vector matrix library, but I don't know why the linker/compiler is not finding it during the link phase?
