SetHarshMode(TRUE);
Your opinion would be interesting if it was motivated by your knowledge and
experience in writing assembly in both AT&T and Intel syntax, so that you could
provide us pros and cons of each approach by your judgement.
Or, if you would be author of that code part in ReactOS.
Otherwise, I’m afraid, it’s just criticizing a very good work, didn’t even
noticing the great PXE milestone, but nitpicking to a syntax. Don’t join
complaints if you can’t fix it. (Timo’s point is valid because that’s him who
actually converts this stuff!)
SetHarshMode(FALSE);
WBR,
Aleksey.

Hi Ged,
Yes of course I read Hervé's mail.
I did not suggest that he should go about porting existing code, I just
expressed my opinion that we shouldn't use AT&T for new code.
As for porting the existing freeldr AT&T code, I guess I could, eventually,
when I get time,
if I can just get a firm enough grip on the AT&T directive voodoo, which is
obscure.
But in the short run, no, sorry, I'm really bogged down by RL :(
(It's even hard to try and keep up with the mailing list)
You wouldn't happen to have a good pointer for that obscure AT&T string voodoo?
Best Regards
L.

Subject: Re: [ros-dev] [EVENTVWR/EVENTLOG] Fix a double off-by-one bug
Hi Gabriel, Eric,
Isn't the real issue why LogFile->Header.CurrentRecordNumber is off by one ?
If that is found and fixed, this patch will make the error re-emerge as an
off by -1.
And if CurrentRecordNumber is actually used as the next *pending* record
number,
the identifier is somewhat mis-leading .. ?
Just my penny to the pot
Best Regards

Subject: Re: [ros-dev] [freeldr] Add PXE "filesystem"
Hi Hervé,
No disrespect for your work, but I'm inclined to concur with Timo regrading
AT&T vs. Intel.
Even though I usually preach "don't fix it if it isn't broken', I really
think that AT&T syntax
is broken by design, and we should use only Intel assembly, which is *much*
clearer.
After all, we're programming Intel CPU's, not AT&T telephone switchboards ;)
1) AT&T does not conform with Intel instruction reference.
Intel syntax conforms with the instruction reference.
2) AT&T has a lot of quaint obscure directive voodoo.
What little directives exist in Intel is clear and concise.
Eventually, I hope we'll get rid of all backwards & muddy AT&T assembly,
but until then I think we should at least not use it for new code.
Best Regards
L.

Hi,
The file is in AT&T syntax, as all asm files in

Sorry, I won't "fix" it, so you'll have to find someone to do it.
