https://codereview.chromium.org/437953003/diff/40001/src/stub-cache.cc
File src/stub-cache.cc (right):

https://codereview.chromium.org/437953003/diff/40001/src/stub-cache.cc#newcod...
src/stub-cache.cc:981: NonexistentFrontend(name, scratch1(), scratch2());
Now this thing will generate a frontend footer with a miss case...

https://codereview.chromium.org/437953003/diff/40001/src/stub-cache.cc#newcod...
src/stub-cache.cc:983: Frontend(receiver(), name);
... (same here) ...

https://codereview.chromium.org/437953003/diff/40001/src/stub-cache.cc#newcod...
src/stub-cache.cc:991: GenerateRestoreName(&miss, name);
... and here goes another miss case. Maybe it would be better to move
FrontendFooter() call from NonexistentFrontend() and rename the latter one to
NonexistentFrontendHeader().
