QUESTION

Does the order of if-conditions inside a loop influence execution speed?

Asked 2020-Nov-14 at 13:57

In order to optimize for execution speed, it is recommended to avoid using if-conditions inside a loop. Imagine there is a case where loop unswitching is not possible, but information (or an estimate) about the frequency of the conditions is available.

Does the order of conditions in an if-else-statement influence execution speed?

Assume I now (or estimate) condition A occurs 80%, B occurs 15% and C only 5% and the times to calculate the conditions is equal. Would it the better to write the loop like this or does the order makes no difference in execution time?

In theory, placing the most likely branch first should be fastest, because less conditions need to be checked. To exchange the order of checks, it is important that for all inputs i, exactly one of the possible conditions is fulfilled.

In practice, you will probably not be able to tell the difference in the performance, because of branch prediction, if you are using a compiled language. A great explanation was provided here. For interpreted languages, this aspect has probably no impact, because the interpreter needs anyway full instructions to read the text line so that the pipelining can't kick in anyway.

If your language features a switch statement, you should probably use it, because there the compiler knows better what it got, so it can pull out maybe some more tricks

QUESTION

gcc -funswitch-loops and -O3

Asked 2020-Oct-10 at 20:49

I'm interested in the loop unswitching optimization option -funswitch-loops to GCC, in particular what actually enables it. According to the documentation:

The following options control optimizations that may improve performance, but are not enabled by any -O options. This section includes experimental options that may produce broken code.

...

-funswitch-loops

Move branches with loop invariant conditions out of the loop, with duplicates of the loop on both branches (modified according to result of the condition).

Enabled by -fprofile-use and -fauto-profile.

So if I'm not already using -fprofile-use or -fauto-profile, it seems that I have to explicitly add -funswitch-loops to my list of compiler flags in order to activate loop unswitching. Fair enough. Though elsewhere in the same documentation, we find

-O3

Optimize yet more. -O3 turns on all optimizations specified by -O2 and also turns on the following optimization flags:

...

-funswitch-loops

...

So the documentation seems to claims that -funswitch-loops is switched on by -O3, but also that it is not turned on by any of the -O options. Which one is it?

...

Answered 2020-Oct-10 at 20:49

You can compile with -v -Q to see a list of all the optimization options that are in effect. With -v -Q -O3 on gcc 10.2, I see -funswitch-loops is included.

So its listing under "not enabled by any -O options" is apparently an error. You could report it as a documentation bug.

QUESTION

"Loop unswitching" optimization is not working

Asked 2019-Nov-30 at 12:41

I heard that Java supports "Loop Unswitching", so I simply tested it in JMH.

I thought they would be exactly the same after JIT. Why is this?

...

ANSWER

Answered 2019-Nov-30 at 12:38

JMH disables inlining of Blackhole.consume method. A non-inlined method is a black box to the JVM - the compiler does not know whether such method modifies fields, throws exceptions, which registers it trashes etc. JIT compiler cannot apply many optimizations across such method call. (Imagine that a black box method uses Reflection to modify bool field, and thus loop unswitching will become invalid).

HotSpot JVM still supports loop unswitching when the compilation scope includes the whole loop body, and the condition is known to be constant throughout the loop.

Consider the modified benchmark:

WPF & C# [Mahapps.Metro] Animating Controls

Asked 2017-Jun-19 at 17:27

I'm starting to learn a little bit of WPF and Mahapps.metro, so I'm pretty new with those ones; here the question:

I have a button and two textboxes, the textboxes visibility is hidden when the forms loads, so when the user clicks the button, the textboxes visibility will be visible, but I want the textboxes to appear with that "slide" animation of the form load that Mahapps provides with the MetroWindow.

I tried using TransitioningContentControl but I couldn't make it happen. I would really appreciate your help, thanks.

Animations in WPF are quite tricky to pull of. I've made a fade animation a while back and it was quite a lot of work. Such a slide animation would require a lot of code and debugging to get it right. My recommendation is use a free slide animation library, and if you are feeling up to the task, you might be able to get a hold of some source code that you can use for inspiration if you want.
