Subject: [ConstantFold] Remove test checking that we don't constant-fold sqrt(-2).
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f103cf347377f8c68822d5e458f3e6ee589893d9;p=llvm

[ConstantFold] Remove test checking that we don't constant-fold sqrt(-2).

This depended on libm's errno behavior (we constant fold iff libm's
sqrt(-2) does not set errno) and was breaking on mac.
