## The computed LMA of a section in a PT_LOAD equals sh_offset-p_offset+p_paddr.
## The byte offset difference between two sections equals the difference between their LMAs.
## Corollary: if two sections are in the same PT_LOAD, the byte offset
## difference equals the difference between their sh_addr fields.
