New Revision: 365307
URL: https://svnweb.freebsd.org/changeset/base/365307

Log:
  Merge commit f26fc568402f from llvm git (by me):
  
    Eliminate the sizing template parameter N from CoalescingBitVector
  
    Since the parameter is not used anywhere, and the default size of 16
    apparently causes PR47359, remove it. This ensures that IntervalMap
    will automatically determine the optimal size, using its NodeSizer
    struct.

  This should fix 'Assertion failed: (Elements + Grow <= Nodes * Capacity
  && "Not enough room for elements"), function distribute, file
  /usr/src/contrib/llvm-project/llvm/lib/Support/IntervalMap.cpp, line
  123.' when building the x11-toolkits/py-wxPython40 port on a i386 host.
