5.7.1.24 Reserve Option
The
-mreserve=ranges option allows you
to reserve memory normally used by the program. This option has the general
form:-mreserve=space@start:endwhere space names the
section which will act as a placeholder and reserve the memory; and
start and end are
addresses, denoting the memory range to be excluded. For example,
-mreserve=data@0x80000200:0x800002FF will reserve memory in both the
kseg0 and kseg1 memory regions (that is, at starting addresses 0x80000200 and 0xa0000200)
using the section reserve_data_0x80000200 as a placeholder. The command
-mreserve=temp@0x9D001000:0x9D001003 will reserve 4 bytes in both the
kseg0 and kseg1 memory regions using the section reserve_temp_0x9d001000.
