   1 // Please note the following:
   2 //   + we are checking that the first bytes of the PPA2 are 0x3 0x0
   3 //     for C, and 0x3 0x1 for C++
   4 //   + the label for the PPA2 seems to vary on different versions.
   5 //     We try to cover all cases, and use substitution blocks to
   6 //     help write the tests. The contents of the PPA2 itself should
   7 //     not be different.
   8 //   + the [[:space:]] combines the two .byte lines into one pattern.
   9 //     This is necessary because if the lines were separated, the first
  10 //     .byte (i.e., the one for the 3) would, it seems, also match
  11 //     the .byte line below for the 34.
