Memory-hole in MIPS ELF file

[Uma shankar]

Hi,

gcc   4.3.3.
binutils    2.19.51
for Linux/MIPS

In executable  ELF file,  I can see a memory-hole between  normal rel
entries and PLT rel entries.

    [ 8] .rel.dyn          REL             007974cc   3974cc   0000b0
08   A  4   0  4
    [ 9] .rel.plt            REL             00798394   398394
0011f0  08   A  4  11  4

Can someone tell me  why this hole exists ?

                thanks
