AsmOne - unwanted optimisations

[Docent]

I noticed that AsmOne (the latest one available) performs some micro optimisations like clr.l -> moveq, it also assembles and.l as andi.l. These of course are equivalent instructions so it didnt bothered me earlier but now I need the exact assembly output. Looked throught docs but didnt find any option to disable this functionality. Is this possible ?
Otherwise, as it seems that the last version was released long time ago, is there a source available so I could fix it ?

There should also be assembler instructions like OPT and BOPT for controlling the optimizations used.

It dont works for all assemblers.
In general assembler autooptimisations = more problems for beginners. It never can be DEFAULT option for good assembler for me.
From my memory, exist minimum 3 type of assemblers for Amiga which assembling same code a few different, f.e cmpi as cmp or vice versa.
Because I used internal EaglePlayer patch routine, then for some patches I cant use code, only dc.l and dc.w. And this is the only solution if You need 100% original code.

I temporarely solved the problem in the same way, but due to source code size (1 mb) I want to keep it readable so I asked.. Seems that I need to switch to another assembler, unfortunately..

You can always place code as comment f. e

dc.w $4E75 ; rts

For me this is enough readable.

Interesting, ASM-One really shouldn't do that if the source is not assembled with enabled optimisations (AO instead of A). This is a bug in my opinion.

Try ASM-Pro that Don Adan linked to in this thread. It is still maintained and it doesn't perform these silent optimisations.
