At least for now, this just checks the +package out from GitHub, verifies that the SHA-256 digest of the +commit we're using matches a known value, and builds the library with +the options we want. + +See tomsfastmath/doc/tfm.pdf for API details. + +In theory, the need for most (perhaps all) of this will go away when +more of the bignum math is implemented in Verilog. Part of the reason +for using the TFM library is that its extremely modular structure make +it easy for us to link in only the functions we need. -- cgit v1.2.3
