            Bug ID: 21195
           Summary: clang emits gcno files to /tmp if -no-integrated-as is
                    used
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

$ clang++ --coverage hello.cpp -c
# hello.gcno in current directory
$ clang++ --coverage hello.cpp -c -no-integrated-as
# hello-XXXXXX.gcno in /tmp

This is because -no-integrated-as causes the assembly gets generated in /tmp,
which is then used to generate the names for the gcno files. Should be fixable
in the driver.
