The defaults assumed by NASM if you do not specify the above
qualifiers are:
\c section .text progbits alloc exec nowrite align=16
\c section .data progbits alloc noexec write align=4
\c section .bss nobits alloc noexec write align=4
\c section other progbits alloc noexec nowrite align=1
\c section .text progbits alloc exec nowrite align=16
\c section .rodata progbits alloc noexec nowrite align=4
\c section .data progbits alloc noexec write align=4
\c section .bss nobits alloc noexec write align=4
\c section other progbits alloc noexec nowrite align=1
(Any section name other than \c{.text}, \c{.data} and \c{.bss} is
treated by default like \c{other} in the above code.)
