             Bug #: 13394
           Summary: gcc 4.6 doesn't inline ibar for unprivileged testcase
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testsuite
        AssignedTo: systemtap@sourceware.org
        ReportedBy: mjw@redhat.com
    Classification: Unclassified


The ibar() function in testsuite/systemtap.unprivileged/foo.c should be inlined
for the unprivileged testcases to work against their .inline probe tests. But
gcc 4.6 doesn't want to inline the ibar function and so we get the following
extra FAILs:

Host: Linux toonder.wildebeest.org 3.1.0-7.fc16.x86_64 #1 SMP Tue Nov 1
21:10:48 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
Snapshot: version 1.7/0.152 commit release-1.6-393-g6e9be5b
GCC: 4.6.2 [gcc (GCC) 4.6.2 20111027 (Red Hat 4.6.2-1)]
Distro: Fedora release 16 (Verne)

FAIL: unprivileged probes: process.function(string).inline
FAIL: unprivileged probes: process(string).function(string).inline
FAIL: unprivileged probes: process.function(string).inline with alias
FAIL: unprivileged probes: process(string).function(string).inline with alias

I haven't figured out yet why gcc doesn't want to inline ibar() in this
version.

Commit 74b8d7b marks these tests as XFAIL when gcc 4.6 is detected.

Ooops, I meant to say KFAIL against this bug.

commit 00873a2: Use __attribute__ ((always_inline)) to force the function to be
inlined.
