Hi,

For my project I want to locate all the global data variables in an ELF
format code. To do this on IA32 and AMD64, we look through the _DYNAMIC
table and locate the relocation table by a d_tag==Elf32_Rel/Elf64_Rela
matching, then go through the relocation table entries and match their
type with R_386_GLOB_DAT/R_X86_64_GLOB_DAT. This mechanism, however,
doesn't work on IA64, because apparently IA64 stores its global data
somewhere else. In the relocation table all I find is function names,
thus there's no global data match.

I was wondering if this is the right direction to go on IA64. Any hint?
Thanks.

C.

IA64 (Itanium) hardware is a completely different architecture and
instruction set; not in any way compatible with IA32/AMD64. And unless i
am mistaken it is big endian as well (x86/IA32 is little endian).
