[llvm-commits] [PATCH] AArch64 backend: LLVM changes

  Minor update on the LLVM side:

  + Most significantly the vfms intrinsic has been removed since it is adequately modelled by an fneg and an fma.
  + Remove spurious whitespace change.

  In addition, it's been suggested in a separate thread that the TLS changes in generic code (around fixELFSymbolsInTLSFixups) should be considered part of this patch, so that they're not divorced of all motivation when committed.

  That leaves one remaining generic change that I would not intend to commit: the change around sint_to_fp. The proper fix is awaiting review on the cfe-commits list. When a version of that is committed I'm expecting no diff from trunk in that area.

  Comments?
