BTW, I'd suggest you to refrain from posting internal organizational
details such
as the NODENAME above, in the public mailing lists.

I have understood that
for x86_64 architecture and linux as operating system , GCC as compiler , the calling convention to be followed is AMD64 ABI.
right?
My doubt is :-
1) Is the above statement true only for stack frames function call etc ?
OR
Is the above statement true for other things related to architecture,
like for knowing data type sizes, endianness, alignment ..
as http://www.uclibc.org/docs/psABI-x86_64.pdf, mentions , data type size alignment etc everything ...
are these things same for AMD and x86 architecture both ???
2)Depending on data type, this above doc defines classes in which a specific data type lie ..
classes like INTEGER, MEMORY , SSE, SSEUP etc ..
are same things applicable in my infrastructure too
OR
they are specific to AMD architecture... if so then whats followed on x86_64 ..
3) is everything in this doc applicable to x86_64 or just a portion of it can be followed
for x86_64 ?
Thanks

1)if i want to get value of a local variable, of a function, from stack trace thats bt-f output, obtained using crash ..
No where AMD64 ABI mentions how local variables are stored ..
is it in some specific sequence of registers ? is it in stack ?
Thanks
Nidhi
