Subject: cmd/gc: can stop tracking gotype in regopt
X-Git-Tag: go1.1rc2~858
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=aa3efb28f02924a451f2c519794cc473b15b7559;p=gostls13.git

cmd/gc: can stop tracking gotype in regopt

Now that the type information is in TYPE instructions
that are not rewritten by the optimization passes,
we don't have to try to preserve the type information
(no longer) attached to MOV instructions.
