### 4.9 `ld` and MSP430

For the MSP430 it is possible to select the MPU architecture. The flag ``-m [mpu type]`' will select an appropriate linker script for selected MPU type. (To get a list of known MPUs just pass ``-m help`' option to the linker).

The linker will recognize some extra sections which are MSP430 specific:

`````.vectors`'`
  Defines a portion of ROM where interrupt vectors located.
`````.bootloader`'`
  Defines the bootloader portion of the ROM (if applicable). Any code in this section will be uploaded to the MPU.
`````.infomem`'`
  Defines an information memory section (if applicable). Any code in this section will be uploaded to the MPU.
`````.infomemnobits`'`
  This is the same as the ``.infomem`' section except that any code in this section will not be uploaded to the MPU.
`````.noinit`'`
  Denotes a portion of RAM located above ``.bss`' section.

  The last two sections are used by gcc.
