Subject: powerpc: Fix register order of a few emit helpers
X-Git-Tag: orc-0.4.33~109
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d3723a51089f669c79a22f9d6e0ec932c7fb4750;p=platform%2Fupstream%2Forc.git

powerpc: Fix register order of a few emit helpers

Two emit helpers had their parameters in the wrong location in
the generated opcode. Hasn't mattered because they were using
the same register for source & dest.

Constant flags are now at the end, so the label should be marked
forward, not backward.
