Subject: [TSan] Build ignore_lib{0,1,5} tests with -fno-builtin
X-Git-Tag: llvmorg-14-init~1404
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d5c34ee5b666e12f92cf5b6e35490e1746fcc5e9;p=platform%2Fupstream%2Fllvm.git

[TSan] Build ignore_lib{0,1,5} tests with -fno-builtin

These tests depend on TSan seeing the intercepted memcpy(), so they
break when the compiler chooses the builtin version.
