I think ELF has only two flags for section declaration viz.
executable and writable (I know it from the docs came with Fasm).

Why we do not have readable flag as well ?
Is it because ELF have no support for readonly data ?

I may be wrong and newer versions of Fasm may allow additional flags.

help

Every ELF section is readable, there's no flag that specifies it.
The ELF executable segments have "readable" flag, however.

So, can I ommit both executable and writable flags and thus have
a read-only section ?
