  21 #    In the spirit of constvars.exp: added volatile, const-volatile stuff.
  22
  23 # This file is part of the gdb testsuite
  24 # Tests for:
  25 #           volatile vars
  26 #           pointers to volatile vars
  27 #           const volatile vars
  28 #           pointers to const volatile vars
  29 #           const pointers to volatile vars
  30 #           volatile pointers to const vars
  31 #           const volatile pointers to const vars
  32 #           const volatile pointers to volatile vars
  33 #           ... etc.  (you get the idea)
  34 # Mostly with char and unsigned char.
