[Linux-ia64] IA64 Link Relocation operators

[Harish Babu]

Hello,

 Could somebody tell me where i could find documentation on IA64 Link
relocation operators.  Where could i find more data about the 
Relocation entries in the object file.  I have gone through the ELF format
and i have some idea about these.  I also wanted to know the different
type of IA64 relocations.  

Thanks
Harish

The only formal documention I know about is in the Assembly Language
Reference Guide available from the Intel web site.  It has a chapter on
Link-relocation Operators.  The explanations are very short, and probably
not understandable unless you have a good understanding of how IA-64
compilers work.

There is also documentation of sorts in the GNU sources.  Gcc has code to
emit assembly using link-relocation operators, GNU as has code to create
relocation entries in object files, and GNU ld has code to evaluate the
relocation operators at link time.

The Itanium psABI document also has a discussion of this; see the end of 
Chapter 4.
