While analysing our space requirements I noted a fairly large discrepancy between the amount of rodata reported by readelf vs adding up the individual symbols reported by objdump --syms. (About a factor 1.5)
As far as I can see, there are two sources for this discrepancy...
1) Alignment. (1 byte symbol followed by a 4 byte aligned symbol)
2) Some large mysterious other thing between the last symbol and the end
of the rodata segment..Question 1) Any ld flags / linking script options / ... that I can use to pack all byte aligned objects together?
Question 2) Any guesses as to what are the mystery rodata items that are not showing up in objdump --syms?
Question 3) Are these problems perhaps an artifact of the somewhat elderly version of the toolchain we are using? ie. Would upgrading solve this problem? sparc-rtems-gcc 2.95.2 sparc-rtems-objdump 2.11
