Subject: InstrProf: Always emit a coverage region for the condition of an if
X-Git-Tag: llvmorg-3.7.0-rc1~11538
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=91f2e3c9c2650795d95c80a7f922054ca74c1ac5;p=platform%2Fupstream%2Fllvm.git

InstrProf: Always emit a coverage region for the condition of an if

When tools like llvm-cov show regions, it's much easier to understand
what's happening if the condition of an if shows a counter as well as
the body.
