After e5822ded562f, the call to LargeFunction can be optimized out, as x
is never accessed in main. This is causing the test to fail, because the
out-of-bounds access won't be executed.
Adding an extra read and returning the value should prevent the
optimizer from removing the call.
Two ASan tests currently `FAIL' on Solaris
AddressSanitizer-i386-sunos :: TestCases/large_func_test.cpp
AddressSanitizer-i386-sunos :: TestCases/use-after-delete.cpp
both for the same reason:
error: no check strings found with prefix 'CHECK-SunOS:'
Fixed by adding the appropriate check strings.
Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.
Differential Revision: https://reviews.llvm.org/D97931
These tests use `--check-prefix=CHECK-%os` but then didn't have
a CHECK line for every os.
In most tests, the linux expectations were sufficient (they match
the "wrap_" prefix with .*), so just remove the check-prefix there.
In the places where this didn't easily work, make sure there are
at least CHECK-Windows and CHECK-Darwin lines.
