Nonetheless, if you can't get ti-20100815 to build with the current

Can you provide more details, here or as a ticket on the mspgcc
project (or
is there already a ticket I've missed)?
I have problems with building libc, as I mentioned.
MacOS 10.5.8 I have:
Select GCC version to build:
1) gcc-4.4.4
2) gcc-4.4.3
3) none
Enter your choice (1-3) [1]: 1
Select GDB version to build:
1) gdb-7.1
2) gdb-7.0.1
3) none
Enter your choice (1-3) [1]: 1
Select Insight version to build:
1) insight-6.8-1
2) none
Enter your choice (1-2) [1]: 2
Select libc version to build:
1) 20100815
2) ti_20100829
3) ti_20100815

Strip debug information
from executables after install? (y/n) [y]
Enter target toolchain path
[/opt/msp430-gcc-4.4.4]: /sw/cross/msp430-ti
And it eventually fails:
msp430-gcc -x assembler-with-cpp -c -mmcu=msp3 -I./../include/ti -
I./../include -I. ./stdlib/div.S -o Build/msp3/div.o
./stdlib/div.S: Assembler messages:
./stdlib/div.S:9: Error: unknown opcode `xpushm'
./stdlib/div.S:24: Error: unknown opcode `xpopm'
make[1]: *** [Build/msp3/div.o] Error 1
Looking at div.S, there is:
#include "../core_common.inc"
/* ldiv() is the same as __divmodsi4() in libgcc */
.section .text
.global div
div:
;; save clobbers first
#if defined(__MSP430X__)
XPUSHM #2, r11
#else
But elsewhere (in core_common.inc), code under __MPS430X__ is
completely disabled and so XPUSHM does not get defined. I don't see
how this compiles on any platform...
