Announcement
------------

The http://LinuxAsmTools.net web site now has
two new releases:

 AsmIDE - IDE (integrated development Environmnet)
 AsmLib_tutor - tutorial for library AsmLib

AsmIDE includes a editor,debugger,reference,library,
and compile assistant.  When a new source file is
created, it provides a template to edit.  It has
support for as,nasm,yasm, and fasm.  

The old development IDE's are still available
as follows:
  AsmFile - file manager for assembler coders
  AsmMgr - older file manager for assembler coders
  AsmEdit - Editor for assembler coding

AsmLib_tutor is a new tutorial for AsmLib. the
tutorial includes example programs and descriptions.
The library (AsmLib) has grown to over 800 functions
and needed a tutorial.

Also, most utilities at http://LinuxAsmTools.net have
been updated.  AsmLib library now has about 800
functions, and the AsmFile (file manager) has been
extended.  Most utilities have bug fixes.

Re: LinuxAsmTools Announcement

[pei lin]

Firstly,Thanks for your great job.

These day i study about linker and loader,i meet a problem which make me puzzle.

when i disassemble *.o object file on x86 machine and find instruction
"call 0xFCFFFFFF",because not link,but why this address 0xFCFFFFFF not
0xFFFFFFFF or others?

i think must have some results i don't know,plz tell me.Because now
young people like me ,most  ly don't familiar with assemble and link.

Best Regards.

First of all, the value is not 0xFCFFFFFF, it's 0xFFFFFFFC
(little-endian), which is the 32-bit equivalent of -4.

And the reason for the -4 is that it's an offset. When the linker
fills in the real address, it will subtract the subroutine's absolute
address from the address of the -4 value to get a relative address,
which it will then add to the existing -4 to get the correct relative
address for the call instruction. And, the reason that 4 needs to be
subtracted is that when the call is executed, it will actually jump
from the end of the call instruction, which is 4 bytes ahead of where
the relative address is stored.
