Subject: [ARM] FMINNAN/FMAXNAN of f64 are not legal.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=1da1d0218a4a98ca639cbf0555768342e6356d78;p=oota-llvm.git

[ARM] FMINNAN/FMAXNAN of f64 are not legal.

This was my error. We've got f32 marked as legal because they're simulated using a v2f32 instruction, but there's no equivalent for f64.

This will get test coverage imminently when D12015 lands.
