[ECOS] MIPS question: _gp = (. + 0x8000);

[Michael Anburaj]

Hi,

I have a question regarding the following line found in a lot of MIPS linker 
scripts:

_gp = (. + 0x8000);

_gp gets loaded into $gp. How does this value ‘_gp’ relate with access to 
.sdata & .sbss session using $gp?

Why is 0x8000 added (to the foot of .sdata section)? To Place $gp halfway in 
the 64KB $gp accessible space??

Can you point to a detailed material on this?

Thanks,
-Mike.
