label table suggestion question

Hi,

I have a question or suggestion, Very Happy

I noticed fasm has an -s option to output symbolic info but I dont know how to utilize that. Confused

my question is whether fasm can output a table of labels for debug.

for example if you divide by zero, then the interrupt handler tells you the instruction pointer, say its 124af3, but how do you find that in the
source code?

lets say the source code is:

Code:


use64
         org 124000h

a:
start:
         mov rax, rbx
         add rax, rcx
.x:   
.y:
        add rbx, rdx
        add rcx, rbx
        add rax, rbx
.z:    and rcx, rax
.t:     ret
abc:   db 5
         db 256 dup( 0 )
         dq 10
         dw 5
z:

then I would like fasm to output a table something like:

Code:

a:
start:
124000h:
124004h:
start.x:
start.y:
124008h:
12400ch:
124010h:
start.z:
124014h:
start.t:
124018h:
abc:
124019h
12401ah
12411ah
124122h
z:
124124h

here the output is that each time a label is reached,

the full version of the label is output, and

each time an instruction is output, the address of that is

output. For data, the labels are also output

and the points demarkated by db dq etc

and dup etc, the syntactic demarkation points.

ie not every byte, but the constructs. However

it would be ok just to have the labels and their addresses

for data. But I need the address of each instruction.

at the end of the output one last address is also output.

Then if I find that there is an error at 12400ch, I can

search the table for 12400ch, and then see that

its the second instruction after start.y and then locate

this in the source code.

can this be done, either now or in the future? Cool

because at the moment I have to insert extra labels,
echo the addresses, and gradually locate where the
problem is in the source code. The problem also is
that the echo code can change the addresses also! Sad

I'm running the code directly on x86 hardware without
intervening OS, thus I need a low level debug feature
such as the above.
