Re: MSP430 RedHat Toolchain Generating Invalid Calls

This version is the one I was using... not the latest. Sorry for the
red-herring...

Old-Version:
Using built-in specs.
COLLECT_GCC=msp430-elf-gcc
Target: msp430-elf
Configured with: ../gcc-trunk/configure --target=msp430-elf
--enable-languages=c,c++ --with-newlib=yes
Thread model: single
gcc version 4.9.0 20130618 (experimental) (GCC)

I rebuilt the toolchain somewhat recently and I get an internal compiler
error so I was using the older version because it seemed to get further
along in the code. I'll checkout the latest gcc code and try another
rebuild.

Here's a quick paste of the internal error I was getting.  I'll try to
reproduce it in a sample soon...

Newer-Version:
Using built-in specs.
COLLECT_GCC=msp430-elf-gcc
Target: msp430-elf
Configured with: ../gcc-trunk/configure --target=msp430-elf
--enable-languages=c,c++ --with-newlib=yes
Thread model: single
gcc version 4.9.0 20131126 (experimental) (GCC)
