Hello rsc@golang.org (cc: golang-dev@googlegroups.com),

I'd like you to review this change to
https://go.googlecode.com/hg/


Description:
cmd/gc: escape analysis to track flow of in to out parameters.

includes step 0: synthesize outparams, from 6600044
step 1: give outparams loopdepth 0 and verify unchanged results
step 2: generate esc:$mask tags, but still tie to sink if a param has
mask != 0
next step: use in esccall (and ORETURN with implicit OAS2FUNC) to avoid
tying to sink

Please review this at http://codereview.appspot.com/6610054/
