  my suggestion:

3872   // Allocate the instance:
3873   // 1) If TLAB is enabled:
3874   //  a) Try to allocate in the TLAB
3875   //  b) If fails, go to the slow path.
3876   //    Else If inline contiguous allocations are enabled:
3878   //  i) Try to allocate in eden
3879   //  ii) If fails due to heap end, go to slow path.
3880   // 2) If TLAB is enabled OR inline contiguous is enabled:
3881   //  a) Initialize the allocation
3882   //  b) Exit.
3883   // 3) Go to slow path.
3884 

Same idea for the SPARC change.

Thanks,
  Thomas
