Hello:
It all started with this message:
msp430-ld: cannot represent machine 'msp:200'
Looking into the mailing list archive, I've found an e-mail from Cyril
Holweck dated on 2006-11-14 which raises the question to the list, some
minutes later he brings up an solution which consists of applying a similar
patch to [1] to binutils. Even this is also affecting MSP430x22xx models, I
will focus on MSP430x2013 which is the one I'm testing with.
This patch modifies the microcontroller name in the bfd_arch_info_type
struct instanced as arch_info_struct. (bfd/cpu-msp430.c:44). I saw the
bfd_mach_msp20 mach value sensible(20) (bfd/bfd-in2.h:1959).
Also in the gcc code, msp430_mcu_types definition of the struct mcu_type_s
you can see (gcc/config/msp430/msp430.c:187)
{"msp430x2013", MSP430_ISA_20, 0},
Providing a value of 20 to this arch as well.
I wasn't sure wether the solution proposed by Cyril was a real solution
or was good enough. I didn't understand where the msp:200 identifier could
came provided the comments before.
After some more research I came across this definition on the file
ld/emulparams/msp430all.sh:
-----8<----------------------------------------
if [ "${MSP430_NAME}" = "msp430x2013" ] ; then
ARCH=msp:20
MACHINE=
SCRIPT_NAME=elf32msp430
OUTPUT_FORMAT="elf32-msp430"
MAXPAGESIZE=1
EMBEDDED=yes
TEMPLATE_NAME=generic
ROM_START=0xF800
ROM_SIZE=0x07e0
RAM_START=0x0200
RAM_SIZE=128
STACK=0x280
fi
----->8----------------------------------------
and hence the problem. I've done an analysis of what's most commonly used
for different models [2]. The rule I get is that arch should be the 2
digits after the MSP430x, except for those starting with MSP430x1 and
having 3 digits after the one, where arch should be 110.
In order to be consistent with this rule I'm proposing the patch [3].
Would anyone have any comment about this subject? I would appreciate them.
Thanks and regards,
