If I recall correctly the data has to be properly aligned for correct access under SPARC else you might see bus-error run time errors..
Correct, a 4 byte int has to be align on a 4 byte boundary.
However, a 1 byte int can (I believe) be aligned on a byte boundary, but there is a performance penalty in accessing it if it is not 4 byte aligned.
Thus if you sorted the rodata items by size, you could pack all the 1 byte items together, then all the two byte items align on a two byte boundary, etc.
Unfortunately the only thing I can find in ld is a script option to *(SORT(.rodata.*)) the item names. No quite what I want, and --sort-common, which seems to do nothing to either the rodata or bss segments.

Somewhere on the edge of a Galaxy, one of literally billions of such galaxies, is a sun, one of literally billions of suns in that galaxy.
Orbiting that sun is a small rock 330000 times smaller than that sun.
This rock is covered by a very very thin scum of life. (Think 6000km of rock followed by a meter or so of biomass.)
Amongst the millions of species in that scum are many hundreds of thousands of types beetle and a mere handful of primates.
Surprisingly enough, this email does not originate from a beetle.
It originates from just one of the 6 billion vastly outnumbered humans.
I trust you will keep this perspective and context in mind when reacting to this email.
