• does passing __m128i objects by reference to inline function cause these objects to be moved to stac

  - by ~buratinas

  Hello, I'm writing transpose function for 8x16bit vectors with SSE2 intrinsics. Since there are 8 arguments for that function (a matrix of 8x8x16bit size), I can't do anything but pass them by reference. Will that be optimized by the compiler (I mean, will these __m128i objects be passed in registers instead of stack)? Code snippet: inline void transpose (__m128i &a0, __m128i &a1, __m128i &a2, __m128i &a3, __m128i &a4, __m128i &a5, __m128i &a6, __m128i &a7) { .... }

• Are compilers smart enough to detect a no-op function?

  - by 0x80

  If I write a function like this: void doMaybeNothing() { #ifndef IM_LAZY doSomething(); #endif } Are modern compilers smart enough to detect a no-op function and optimize so that there are no cycles wasted? Or is there always a small performance impact?

• How did it happen that "static" denotes a function/variable without external linkage in C and C++?

  - by sharptooth

  In C static can mean either a local variable or a global function/variable without external linkage. In C++ it can also mean a per-class member variable or member function. Is there any reference to how it happened that the static keyword that seems totally irrelevant to lack of external linkage is used to denote lack of external linkage?

• Can Visual Studio manage function prototypes for me in C++ header files?

  - by Gibybo

  In C++, the common practice is to declare functions in header files and define them in cpp files. This leads to always having two copies of every function's prototype. Then whenever I want to change a function's name/return value/parameter, I have to manually change it in both files. This seems unnecessarily tedious and there must be lots of people that share my pain, so is there a way to automate these changes between files in VS? Bonus points for vim solutions as well.

• How can I locate .NET Library property/function that return a particular type?

  - by Michael Bray

  Occasionally I will know that there is a .NET Framework function that returns a particular type of object, but I can't recall the property or function name. It would be really nice to be able to somehow scan the Framework or other DLL for functions that return a particular type of object. (For example, it would have helped when I asked this question, and I have a similar question again.) Can anyone suggest how I might do this?

• How do I change the default sounds for the calendar warning function in CE 5.0?

  - by Joe M

  I have an old Moto Q that I would like to change the default alarm sound in the Calendar function. Right now, it seems to pick up the Alarm4.mid file in the Windows directory, which is embedded in ROM, so the filenames can't be changed. Is there a way to change the file pointer in the Calendar function to another file or is there another way to get around this?

• Static variables within functions in C++ - allocated even if function doesn't run?

  - by John C

  I've been reading up on C++ on the Internet, and here's one thing that I haven't been quite able to find an answer to. I know that static variables used within functions are akin to globals, and that subsequent invocations of that function will have the static variable retain its value between calls. However, if the function is never claled, does the static variable get allocated? Thanks

• Should i use a C function or Obj-C Method?

  - by Daniel Granger

  I'm about to create a function which adds to NSDateComponents together is there any advantage to putting this in a C style function or should it go in a Obj-C method? Is there ever a reason to use one rather then the other or should I always stick to Obj-C? BTW: Not that it makes any difference I'm sure but this is for an app on the iPhone Many thanks

I guess I don't know specifically what I'm looking for.
