## flags to test what we dump when bits in the OS and processor specific ranges are set.

## SHF_MASKPROC has a value of 0xf0000000, SHF_EXCLUDE has a value of
## 0x80000000. When SHF_EXCLUDE is mixed with other processor specific
## flags, GNU readelf does not necessarily print "E", because it handles
## the SHF_MASKPROC mask first. It only prints "E" when there are no other
## processor flags set. Check llvm-readelf output matches GNU.
