[PATCH] D57054: [MachineOutliner][ARM][RFC] Add Machine Outliner support for ARM

[Yvan Roux via Phabricator via cfe-commits]

Thanks for the comments Sam,

Thumb1 is disabled in this version (see inline comment).

The is to bundle Machine Outliner to -Oz like it was done for AArch64, but here it just run when the flags are used (-moutline for clang or -enable-machine-outliner for llc) and not all the time.

Ok I'll try see if I can split it on the  outlining kind as you suggest.



================
Comment at: llvm/lib/CodeGen/MachineOutliner.cpp:1159
+  MF.getProperties().reset(MachineFunctionProperties::Property::IsSSA);
+  MF.getProperties().set(MachineFunctionProperties::Property::NoPHIs);
+  MF.getProperties().set(MachineFunctionProperties::Property::NoVRegs);
