[PATCH] D57044: [AArch64] Optimize Inf materialization

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Is there some reason we're checking for specific floating-point constants here, as opposed to just calling AArch64_AM::isLogicalImmediate or AArch64_AM::isAnyMOVWMovAlias?



================
Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:5430
+  // We can materialize #0.0 and #INF as fmov $Rd, XZR for 64-bit and 32-bit
+  // cases.
   // FIXME: We should be able to handle f128 as well with a clever lowering.

This comment is wrong.
