Subject: [asan] Allow propagating env variables when testing on iOS Simulator
X-Git-Tag: llvmorg-5.0.0-rc1~6600
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=74233bed59a47cd9cf52adb0a22c4dcee38dc5fb;p=platform%2Fupstream%2Fllvm.git

[asan] Allow propagating env variables when testing on iOS Simulator

This patch adds "%env" as a way to express that the environment variable should be set on the target device/simulator. This fixes some test failures when testing on iOS/Simulator.
