Revert r372893 "[CodeGen] Replace -max-jump-table-size with -max-jump-table-targets"
This caused severe compile-time regressions, see PR43455. > Modern processors predict the targets of an indirect branch regardless of > the size of any jump table used to glean its target address. Moreover, > branch predictors typically use resources limited by the number of actual > targets that occur at run time. > > This patch changes the semantics of the option `-max-jump-table-size` to limit > the number of different targets instead of the number of entries in a jump > table. Thus, it is now renamed to `-max-jump-table-targets`. > > Before, when `-max-jump-table-size` was specified, it could happen that > cluster jump tables could have targets used repeatedly, but each one was > counted and typically resulted in tables with the same number of entries. > With this patch, when specifying `-max-jump-table-targets`, tables may have > different lengths, since the number of unique targets is counted towards the > limit, but the number of unique targets in tables is the same, but for the > last one containing the balance of targets. > > Differential revision: https://reviews.llvm.org/D60295 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@373060 91177308-0d34-0410-b5e6-96231b3b80d8
