Add support to the MSP430 linker for the automatic placement of code and data into either low or high memory regions.
gas * config/tc-msp430.c (MAX_OP_LEN): Increase to 4096.
(msp430_make_init_symbols): New function.
(msp430_section): Call it.
(msp430_frob_section): Likewise.
ld * emulparams/msp430elf.sh (TEMPLATE_NAME): Change to msp430.
* scripttempl/msp430.sc (.text): Add .lower.text and .either.text.
(.data): Add .lower.data and .either.data.
(.bss): Add .lower.bss and .either.bss.
(.rodata): Add .lower.rodata and .either.rodata.
* emultempl/msp430.em: New file. Implements a new orphan
placement algorithm that divides sections between lower and upper
memory regions.
* Makefile.am (emsp430elf.c): Depend upon msp430.em.
*emsp430X.c): Likewise.
* Makefine.in: Regenerate.
