Subject: cmd/internal/ssa: correct references to _gen folder
X-Git-Tag: go1.20rc1~565
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=85196fc982ead65ea56c377c2e381eabff329773;p=gostls13.git

cmd/internal/ssa: correct references to _gen folder

The gen folder was renamed to _gen in CL 435472, but references in code
and docs were not updated. This updates the references.
