> When using --no-huge mode, dynamic allocation is not supported.
> Because of this limitation, the option --legacy-mem is implied
> and -m may be needed to specify the amount of memory to allocate.
> Otherwise the default amount MEMSIZE_IF_NO_HUGE_PAGE will be allocated.

Or better:

"Static memory layout is selected, "
"allocation can be increased with the option -m\n"
