[PATCH][10/10] -fuse-caller-save - Add test-case

[Tom de Vries]

Richard,



This patch series adds analysis of register usage of functions for usage by IRA.

The original post is here

( http://gcc.gnu.org/ml/gcc-patches/2013-01/msg01234.html ).



This patch adds a test-case for -fuse-caller-save.  Since the test-case has

different output for mips16 and micromips, new effective targets are introduced.



Build and reg-tested on mips.



OK for trunk?



Thanks,

  -Tom
