Greetings everyone!
I got little question about section alignment.
Is there possible to change default value of that to any other value ? if it is, how can I do that ? Thank you.
as I found in search results, it's not possible to apply arbitrary values to it. Can developers add such function to FASM ? It would be great! (at least, for me.)

If you have specific requirements for section alignment then you can edit the fasm source to generate whatever alignment you require. The short answer is yes. But you will have to provide a good argument for why it is necessary to provide the "developers" with an incentive to make time include it. And until such a time comes (if ever) when the "developers" (aka Tomasz) adds such a thing when just use my first suggestion above.

Modern Windowses doesn't accept arbitrary values. If you need to squeeze file alignment for some older OS, you will probably not mind that much to bake your own PE.

I'm not too familiar with ELF, are there segment alignments there?

Hi, I though this option will reduce size of executable when compiled (saw example on VC++ compiler with #pragma comment(linker,"/align 200" or something, don't remember.) That's the only the reason, nothing else. If it's false, just ignore this thread.

I'm don't know ELF formats yet, but gonna learn soon, cause I'm going to move to Unix/Linux systems.

I agree with the suggestion. The feature is not as important as e.g. custom default stack size specification, but for the sake of completeness it makes sense to allow also file and section alignment customization with an additional directive of the same kind as entry or stack.

Just wanted to ask, whether you have any plans regarding the topic.

No. By PE specification, the file alignment cannot be less than 512 bytes, and I see no reason why one would need bigger alignment, as it would only increase the file size. If it was just to have the option just for the sake of it, then it would not be worth the amount of work required to adjust the formatter.

Fair enough. Thanks for the information.
Then the officially invalid alignment values, starting from 4, are going to be achievable only by the manually created PEs.
