Subject: [asan][test] Fix SED issues with macOS (BSD)
X-Git-Tag: upstream/17.0.6~26007
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=87d0ff91176221894604aa07fc0e2b8492140f7d;p=platform%2Fupstream%2Fllvm.git

[asan][test] Fix SED issues with macOS (BSD)

SED differs between GNU and BSD in handling semicolon and the use of
'\n' in regex patterns. For macOS we can't use these GNU extensions.
