[PATCH] D120000: [1/2] TLS loads opimization (hoist)

[Xiang Zhang via Phabricator via llvm-commits]

xiangzhangllvm added a comment.

Clear now. The createCleanupLocalDynamicTLSPass is integrated in ISel , it is mostly a local/peephole optimization for variables with same TLS base address.
It can't analysis the TLS variables in different BBs or Loops. PLS refer name <https://godbolt.org/z/f7WrqK5he> 
But it is a good supplement for current patch. because it can optimize different TLS variables in local. (Current patch is focus on same TLS variable which used in different BBs or Loops)
