- Subject: [patch] Add v850-*-rtems*
Hi,
The patch below adds an v850-*-rtems* target configuration to GCC.
It's a sightly modified copy of the v850*-*-* target, with some RTEMS
specific changes added.
I would like to apply this patch to trunk and gcc-4_7-branch.
OK to commit?
Ralf

* config.gcc (v850-*-rtems*): New target.
* config/v850/rtems.h: New.
* config/v850/t-rtems: New.
