Are Programmable Logic Devices (PLDs) obsolete because of FPGAs? Do you dislike the way combinatorial loops are not an easy accident with PLDs? Were RISCs up-to-date when Hennesy and Patterson claimed to have invented the idea in the 1980's with a publication of theirs cited in their book "Computer Architecture - A Quantitative Approach", despite the claims of users of Microchip PICs that Microchip invented RISCs (without the term RISC) in the 1970's? Should sequential programs which achieve what is required of them be replaced? I own a lot of video tapes. Many of them were bought after DVDs became common. Should I have bought their alternatives on DVDs instead, simply to spend more money for something which someone else thinks is better? |--------------------------------------------------------------------------------------------------| |" This | | suggest that LLVM to be on the cuting edge, [..]" | |--------------------------------------------------------------------------------------------------| I do not expect the Ada to C part of LLVM to be even nearly as good as Taft's Ada 95 to C with POSIX compiler, so how could it be cutting edge? Do you criticise people for using GNAT instead of compilers which perform better?
