Quote from: NoCforMe on June 24, 2025, 09:00:25 PMSo it's better not to align a proc???
I thought it should be like that with Align vs unaligned  proc start,because innerloop some opcodes later ends up aligned

Excellent point; hadn't thought of that.

It's not necessarily the proc's entry point that you want aligned:
it's whatever instruction that marks the start of a time-sensitive part of the proc, a loop or whatever.
So the alignment should probably be done inside the proc, not outside.

Funny, in my case NEAR jumps didn't make jumps faster, on the contrary
