[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Number of thunks with difference choices of getThunkSectionSpacing:

  A
  
  0: 79692
  0x2000000-0x10000: 78449
  0x2000000-0xc000: 78336
  0x2000000-0x8000: 78332
  0x2000000-0x4000: 78386
  0x2000000-0x2000: 78365
  0x2000000-0x1000: 78345
  0x2000000-0x0000: 78320
  0x2000000+0x4000: 78334
  
  B
  
  0: 112315
  0x2000000-0xc000: 112474
  0x2000000-0x8000: 112333
  0x2000000-0x4000: 111937
  0x2000000-0x0000: 111838
  0x2000000+0x4000: 111851
  0x2000000+0x8000: 111847

The "simplest" number 0x2000000 works no worse than other numbers so I'll just use it.
