and from that point it behaves in the same way as an in-order core. A compiler can of course perform loop pipelining or UAI, but with large loops it gets more difficult to perform such optimization and maintain result correctness. So, it might pay off to do such optimizations even i...
The code I posted above is an ad-hoc adaption of some code I have had sitting around for quite a few years. I seem to recall that I chose the particular arrangement of FMAs used so as to minimize register bank conflicts, but I do not know for sure. Having been retired for almost a...

tail recursion optimization should be applied in recursive functions when the recursive call is the last operation performed in the function. by ensuring the recursive call is in tail position, compilers and interpreters can optimize the function to reuse the same stack frame, reducing the memory ...
Code reviews are a good place to advocate for and learn about good programming habits.” What are some bad coding habits that you wish every developer would stop doing? Many bad coding habits stem from overvaluing personal preferences or ability. For example, writing code that doesn’t conform...
The code itself is simple enough but the black part is inside 3 level of do-loops. When n becomes large, this simple number comparison is called many many times. Is there a simple way to optimize this code, or is there a function that will perform the function (compare the value of ...
A JIT-compiler can not only look at the code and thetarget system, but also at how the code is used. It can instrument the running code, and make decisions about how to optimize according to, for example, what values the method parameters usually happen to have. ...
improve performance. techniques like loop unrolling, loop fusion, and loop parallelization can be used to optimize loops and make them more efficient. however, these optimizations are typically handled by compilers or advanced programming techniques. how do loops contribute to the efficiency of programs...
