Sure, more information that way is useful. Sending a patch is always appreciated.

We had a need for calculating an ELF section load address, essentially the LMA address printed out from GNU objdump with the –h option:
Sections: Idx Name Size VMA LMA File off Algn 0 .start 00003dc0 00000000 00000000 00001000 2**6 It looks like GNU binutils calculates this by applying the delta between the vaddr and paddr of the section's enclosing segment. I implemented this inside llvm-readobj: Section { Index: 30 Name: .strtab (9) Type: SHTSTRTAB (0x3) Flags [ (0x0) ] Address: 0x0 Load Address: 0x0 Offset: 0x64FF88 Size: 2689979 Link: 0 Info: 0 AddressAlignment: 1 EntrySize: 0 } Is there interest in this being upstreamed? It's a small patch. Is this the best place to put this information inside of llvm-readobj and underneath the 'Address:' line. If there's a better place let me know. Qualcomm Innovation Center, Inc.
