I'm trying to turn on a flag (-inline-generic-switch-cost) introduced in
r301649 which improved the inline cost heuristic for switch. In my
experiment for LLVM test suite and spec2000/2006 in AArch64, +17.82%
performance and -8% code size reduce was observed in spec2000/vertex
with O3 LTO. No significant code size / performance regression was found
Before we turn this flag on by default, I want this change to be tested
on other targets as well as for other applications. Can anyone please
take a change to test this and share the result in D32653.
