2013 C++ LLVM compiler talk video

shared by Fabien Cadet on 28 Dec 13 - No Cached
  • Last year I described C++ as bearing the cautionary label ‘Here Be Dragons.’ And yet we’re all still writing C++ because it is the best programming language for the problems we face. In turn, we need a strategy to deal with the “dragons” that reside in large C++ code bases. The Dragon Book (my old compiler textbook) taught about a collection of tools to address the complexity of compiler design, and while our challenge is somewhat different, the approach remains the same. When a mere mortal programmer ventures forth to battle the complexity of large software systems in C++, they’re going to need some really good tools to help them. At Google, we’ve been building up a platform of such tools. I will introduce the platform and toolset, and show how to use them to write fast and correct C++ code, quickly and correctly.I will also give a peek into the future of the next generation of tools we’re working on and some of the really interesting changes to C++ that are coming in the next few years to help both programmers and these tools be ever more effective.

  • Here's the problem. C and C++ suck rocks as languages for numerical computing. They are not the fastest, not by a longshot. In fact, the fundamental design of them makes it pretty much impossible to make really good, efficient code in C/C++.

    At first I thought this could be the "back" part of TIM, but after trying it out on even simple example text, I'm a bit dissapointed. The nested lists, images, and URLs seem broken (although the links at least, work in Confluence).

    The worst problems are that it has no sense of %{style} span% or footnotes, and no concept AT ALL of tables.  It would be nice to at least get the {style} -- and therefore the spans -- working.

Fabulous Adventures In Coding : The Stack Is An Implementation Detail, Part One - 0 views

clr cli .NETGeneral c# memory allocation

shared by Matteo Spreafico on 14 Aug 09 - Cached
  • Almost every article I see that describes the difference between value types and reference types explains in (frequently incorrect) detail about what “the stack” is and how the major difference between value types and reference types is that value types go on the stack.
  • I find this characterization of a value type based on its implementation details rather than its observable characteristics to be both confusing and unfortunate. Surely the most relevant fact about value types is not the implementation detail of how they are allocated, but rather the by-design semantic meaning of “value type”, namely that they are always copied “by value”.
  • Of course, the simplistic statement I described is not even true. As the MSDN documentation correctly notes, value types are allocated on the stack sometimes. For example, the memory for an integer field in a class type is part of the class instance’s memory, which is allocated on the heap.
  • ...3 more annotations...
  • As long as the implementation maintains the semantics guaranteed by the specification, it can choose any strategy it likes for generating efficient code
  • That Windows typically does so, and that this one-meg array is an efficient place to store small amounts of short-lived data is great, but it’s not a requirement that an operating system provide such a structure, or that the jitter use it. The jitter could choose to put every local “on the heap” and live with the performance cost of doing so, as long as the value type semantics were maintained
  • I would only be making that choice if profiling data showed that there was a large, real-world-customer-impacting performance problem directly mitigated by using value types. Absent such data, I’d always make the choice of value type vs reference type based on whether the type is semantically representing a value or semantically a reference to something.

  • The biggest question left unanswered in my mind is the role state will play in software of the future.
  • The biggest question left unanswered in my mind is the role state will play in software of the future. That seems like an absurd statement, or a naïve one at the very least.  State is everywhere: The values held in memory. Data locally on disk. Data in-flight that is being sent over a network. Data stored in the cloud, including on a database, remote filesystem, etc. Certainly all of these kinds of state will continue to exist far into the future.  Data is king, and is one major factor that will drive the shift to parallel computing.  The question then is how will concurrent programs interact with this state, read and mutate it, and what isolation and synchronization mechanisms are necessary to do so?
  • Many programs have ample gratuitous dependencies, simply because of the habits we’ve grown accustomed to over 30 odd years of imperative programming.  Our education, mental models, books, best-of-breed algorithms, libraries, and languages all push us in this direction.  We like to scribble intermediary state into shared variables because it’s simple to do so and because it maps to our von Neumann model of how the computer works.
  • ...3 more annotations...
  • We need to get rid of these gratuitous dependencies.  Merely papering over them with a transaction—making them “safe”—doesn’t do anything to improve the natural parallelism that a program contains.  It just ensures it doesn’t crash.  Sure, that’s plenty important, but providing programming models and patterns to eliminate the gratuitous dependencies also achieves the goal of not crashing but with the added benefit of actually improving scalability too.  Transactions have worked so well in enabling automatic parallelism in databases because the basic model itself (without transactions) already implies natural isolation among queries.  Transactions break down and scalability suffers for programs that aren’t architected in this way.  We should learn from the experience of the database community in this regard
  • There will always be hidden mutation of shared state inside lower level system components.  These are often called “benevolent side-effects,” thanks to Hoare, and apply to things like lazy initialization and memorization caches.  These will be done by concurrency ninjas who understand locks.  And their effects will be isolated by convention.
  • Even with all of this support, we’d be left with an ecosystem of libraries like the .NET Framework itself which have been built atop a fundamentally mutable and imperative system.  The path forward here is less clear to me, although having the ability to retain a mutable model within pockets of guaranteed isolation certainly makes me think the libraries are salvageable.  Thankfully, the shift will likely be very gradual, and the pieces that pose substantial problems can be rewritten in place incrementally over time.  But we need the fundamental language and type system support first.
