Re: Inline Assembler Problems

DOHHH! I am an idiot! In my code I had the two operands switched around!

The

assembler was telling me that I was using an invalid 386 instruction. Is

the

following really illegal?

movl %eax,$_TheArray(,esi,4)

First of all: ESI must be preceding by an "%" symbol __ALSO__ if it is between the brackets (have you get my doc?). Without this the assembler always will tell you that you was using an invalid 386 instruction. Are you sure that your variables are __static__, too?

BTW I found a new real problem. With:

movl %%eax, $_TheArray(,%%esi,4)

I receive the same invalid 386 instruction error message. Mmmh...I investigate on this. I have found this (probably) bug in the "as":

movl $_TheArray(,%%esi,4), %%eax

and

movl %%eax, _TheArray(,%%esi,4)

is accepted from the assembler without any problems. But sadly:

movl %%eax, $_TheArray(,%%esi,4)

is refused. If this isn't a bug, anyone know the reasons?

I LOVE the inline assembler, except for the 15 local label limit. I know

I

can prefix locals with an 'L' except when the compiler inlines the

codeit

creates duplicate labels. Is there any way around that?

In my doc i wrote that the labels can be from 0 to f only because I don't use more than 15 local labels at time. But of course, if you want, you can use for example "16:" or "19:" for indicate a local label, and this work fine.

That's all folks!!
