[PATCH] D63692: [LSR] Improved code generation for Zero Compare loops

[Craig Topper via Phabricator via llvm-commits]

I'm not sure why your examples have push instructions to load an immediate into registers unless you're compiling with -Oz? And if that's the case then changing push/pop to mov is an increase in code size.
