Warning: MASM generates wrong operand size in opcodes:
smsw/sldt/str reg.
Explonation:
Intel ia32 allow 32 bit registers as operands to {smsw/sldt/str reg } opcodes.
yet MASM generates error message "bad operand size" when meet 32 registers
as operands to these instructions.
But there are more problems to it.
If you enter 16 bit register as operand with the instructions MASM actually
generates opcode for 32 register.
For example if you enter
sltd ax
MASM generates opcodes for sltd eax.
So to generate opcode sltd eax
you need enter
sldt ax
and to genrate opcode for sldt ax
you need enter
db 66h
sldt ax.

Hi Svin!

Did you try the new Macro Assembler version 7? (ml.exe)


This link from Natas:

You got mail.

Hehe, sent. Check your mail again and keep your finger away from the DEL key.

With your and bazik help I did :)
The same problem, nothing changed.

May be there are new features, along with old bugs :)

I tried more new link and ml and got so many problems that replaced it back with an old ones.

bazik,
Did you check other assemblers with the errors I mentioned or you just suggest me to right everything in HEX?
:)

So you recommend FASM?
The question was if you did check it :)
We talked with him only about smsw and he said he fixed it. Good for FASM users.
I don't know about the other commands
But did you check it and the other commands, when you
recommend me not use MASM?
Before you have it done, your arguments are based on nothing but rumors.
FASM wins more and more respect as I can see, but I spent to many time to get used to MASM, to switch to anything else before I'm sure it's critically better.

donkey,

Can you send me your e.mail address,then I can send you a zip file containing the new ml.exe and
the other tools. :)

Regards,

Vortex
