Subject: [msan] Don't EXPECT_POISONED beyond the we_wordv
X-Git-Tag: upstream/15.0.7~33109
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c699b1cd04df33cbf6e9f84272cd3309e7cc984;p=platform%2Fupstream%2Fllvm.git

[msan] Don't EXPECT_POISONED beyond the we_wordv

Partially reverts commit 629411d799223d7bc7aad98661b1443a4788c0c5.

EXPECT_POISONED argument is outside of the allocation so we can't
assume the state of shadow there.
