            Bug ID: 26660
           Summary: probe kernel.statement(HEX).absolute incorrectly
                    requires kernel debuginfo
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: agentzh at gmail dot com
  Target Milestone: ---

To use stap to translate the following stap script:

```
probe kernel.statement(0xffffffff881075a0).absolute {
    println("Hit")
    exit()
}
```

we got the following error when kernel debuginfo is not present in the current
system:

```
semantic error: while resolving probe point: identifier 'kernel' at a.stp:1:7
        source: probe kernel.statement(0xffffffff881075a0).absolute {
                      ^

semantic error: while resolving probe point: identifier 'kernel' at :1:7
        source: probe kernel.statement(0xffffffff881075a0).absolute {
                      ^

semantic error: missing x86_64 kernel/module debuginfo [man warning::debuginfo]
under '/lib/modules/5.0.16-100.fc28.x86_64/build'

Pass 2: analysis failed.  [man error::pass2]
```

But actually this probe point does not need kernel debug symbols at all.

I'll prepare a patch to fix it.
