Looks like purebasic passes -O2 parameter to gcc when you enable optimizations (i see -O0 and -O2 strings inside pbcompilerc.exe).

Optimization is not for source code but for a compiled binary file. It is just a gcc flag (/Ox). PureBasic just translates pb code to c code and then gcc does optimizations.

Replace #PB_EventType_LeftClick with #PB_EventType_Change

The simplest solution i can think of is with a constants. ; ============ Declarations CompilerIf Not Defined (_BoutonDessin_declared, #PB_Constant) Debug "The declaration has not been made, I declare it!" Declare BoutonDessin() #_BoutonDessin_declared = 1 CompilerElse Debug "The decla...

Now, let do the same with Rust and you're in pole position. There is no point in doing that because you can only get unsafe rust code. But, if you really want that, you can do it already. Get c code with /commented flag and then run it through c to rust transpiler (for example https://c2rust.com/).

This bug was already reported. Temporary fix until new update is to disable OnError lines support.

but I have noticed the C compiled programs are about 30% bigger. I have not noticed that. Maybe you are using some libs (UseSQLiteDatabase(),UsePNGImageEncoder(),...) in your apps that are now updated with a new PB version. Or you are maybe comparing 64bit exe with a previous 32 bit exe. Also make ...

I finally figured out why i get that huge difference. I made a mistake and was compiling with PB 5.72 and not PB 5.73. It looks like there was a problem in PB 5.72 compiler (and maybe in older versions) . Here are new results (average from 5 runs): 5.72 x64: threadsafe enabled: 2072 threadsafe disab...

I was talking about this code snippet from other thread:

Thanks for testing. It looks like i am the only one with a huge difference for that code snippet.

Can you run it without debugger (compiler -> compile without debugger) and post number of passes you get for each case? Thanks

My results with PBx64 with 10 runs: with vars: 1222-1263 vars commented out: 1245-1290 Barely any difference (~2%) compared to yours (~25% difference). Can you also test this code: https://www.purebasic.fr/english/viewtopic.php?p=567877#p567877 ? I have 30% speed difference on my system with that co...

Trust me, K&R is horrible when the code gets large and inline comments and multiple developers. Allman solves all that noise. Clang-Format solves all that noise. Each company has its own style guidelines and each developer can just write code in their own personal style of choice but before com...
