9232	Template bloat	Domagoj Šarić	John Maddock	"With integers of size N powm() will instantiate divide_unsigned_helper<> for N and N*2, since this is a very large function this leads to classical template bloat.
Examining the codegen it appears that both instantiations are nearly identical save for immediate constants -> this would suggest that you could refactor divide_unsigned_helper<> (and probably the rest of the library) so that it separates functionality that actually depends on template parameters from template-parameter independent code into separate functions (in this case divide_unsigned_helper would probably call a helper function that takes the size of the number as a runtime parameter).

ps. even when different function template instantiations result in identical code there are _still_ lousy compilers&linkers that will not merge them (Clang we are looking at you: http://llvm.org/bugs/show_bug.cgi?id=11633)..."	Bugs	new	To Be Determined	multiprecision	Boost 1.54.0	Optimization
