Please note:

We noticed that CheckNotRegistersEqual is not actually called from anywhere.
This patch contains the implementation anyway, assuming it may be used in the
future.

If these are not used at all, I suggest removing them completely for all
platforms before they bit-rot. Adding Erik for a second opinion.

rebased on r11230

We can't land this because it adds unused code (CheckNotRegistersEqual) to MIPS,
when it should be removing it from all architectures.

The ...afterminus method does seem to be used, albeit very rarely.

Thanks for the review.

I took the liberty of updating this CL to remove all the code related to
CheckNotRegistersEqual from all architectures.

If you would rather have this change in a separate CL, let me know and I'll make
that change.

Please separate the CLs so that the code that needs to be landed for MIPS in 3.9
is in its own CL.

Done. This patch now only implements CheckNotCharacterAfterMinusAnd.

LGTM, landed as 11314

[kalmard, 2012-04-14 08:20:06]

Thanks for landing! Closing.
