Subject: [SystemZ]  Remember to reset the NoPHIs property on MF in createPHIsForSelects()
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1ca3aae4063f87c27882df51d7293d1bf0063a33;p=llvm

[SystemZ]  Remember to reset the NoPHIs property on MF in createPHIsForSelects()

After creating new PHI instructions during isel pseudo expansion, the NoPHIs
property of MF should be reset in case it was previously set.
