For [future] reference. PIC-ification on MIPS involves setting up $gp
(achieved with .cpload directive under o32) and addressing relative to
its value (achieved with .option pic2 directive). E.g. here is how 'la
$n,label' is expanded without .option pic2 directive:
lui $n,xxxx
addiu $n,yyyy
where xxxxyyyy is absolute value, which needs to be adjusted if code is
relocated. And here is with .option pic2 directive:
lw $n,xxxx($gp)
addiu $n,yyyy
where xxxx and yyyy are disjoint "magic" values composed at link time in
position-independent manner. And you should avoid non-PC-relative
instructions, more specifically j[al], and adhere to b[al] instead. A.
