File test/mjsunit/compiler/concurrent-invalidate-transition-map.js (right):


https://codereview.chromium.org/180053003/diff/1/test/mjsunit/compiler/concurrent-invalidate-transition-map.js#newcode47
test/mjsunit/compiler/concurrent-invalidate-transition-map.js:47:
add_field(obj);
If GC happens between the calls and there is no live instance of new_object
then
then transition in add_field will be collected, so on the next call to
add_field
the obj.c IC will not turn MONOMORPHIC.

LGTM.
