[PATCH] D26748: [ARM] Relax restriction on variadic functions for tailcall optimization

[Pablo Barrio via llvm-commits]

Hello @rengolin , @olista01 ,

Could you have a look at this patch? I see no reason to restrict the tail call optimizations to variadic functions: the AAPCS restrictions seem to be already checked for non-variadic functions. The LLVM regression tests passed, and I have also tested with a few benchmarks and they all seem to work fine.

Please shout if I overlooked something. New test suggestions will be also very welcome.

Thanks,
Pablo
