Hi All,

I am using crash tool to analyze core dump obtained from red hat linux
on
x86_64 platform.

Putting some of the doubts..

a)like which sequence the parameters, return address, etc are pushed
on stack?

May be you would like to take a look at below link:
http://www.cs.virginia.edu/~evans/cs216/guides/x86.html [Section: Calling Convention] has the exact answer to your question.

b)Which registers are used, if some registers play some spl. role ?

You also might want to read the tutorials:
http://cocoafactory.com/blog/2012/11/23/x86-64-assembly-language-tutorial-part-1
This tutorial is in four parts. Part-2 has information on all the registers and their roles.

c)lets say for a program a.c i use gcc -S a.c ...do we have some other
command to generate somewhat more clear assembly code, may be with
some comments in English

Take a look at information on objdump command. You can compile the debug binary of the code and use objdump with certain options on that binary- this will dump the assembly code along with inline C code.

Any kind of help in understanding this will be appreciated ..

Thanks
Nidhi

Hope it helps.
