Subject: [X86] Now unreachable handling for f64->v2i32/v4i16/v8i8 bitcasts from ReplaceNodeRes... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f0043317b1e975772a774b8073cb98edb2885f9a;p=llvm

[X86] Now unreachable handling for f64->v2i32/v4i16/v8i8 bitcasts from ReplaceNodeResults.

We rely on the generic type legalizer for this now.
