           Summary: testcase gcc.dg/2020103-1.c faiils with "scan-assembler-
                    not LC"
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: target
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dank at kegel dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: powerpc-unknown-linux-gnu

I'm building and testing gcc with http://kegel.com/crosstool
for ppc405 and ppc750.  On those processors, I see the test failure
FAIL: gcc.dg/20020103-1.c scan-assembler-not LC
I've tested both gcc-3.3 (release) and gcc-ss-3_3-20030714, same problem.

This also showed up on the 3.4 branch on powerpc-ibm-aix4.3.3.0; see
http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg01265.html
and on the 3.1 branch on powerpc-unknown-netbsd1.5ZC; see
http://gcc.gnu.org/ml/gcc-testresults/2002-05/msg00770.html
It also shows up in Debian's tests for 3.2.3 and 3.3.

I can confirm this in 3.3.1 (20030714), will be trying the mainline soon.

The testcase is wrong; the LC's that are in the generated
code have nothing to do with spilling, but just with
loading the addresses for the call to f2.

[janis at gcc dot gnu dot org]

------- Comment #12 from janis at gcc dot gnu dot org  2008-12-12 19:37 -------
Fixed.

>From the patch mail:

The scan assembler check in gcc.dg/20020103-1.c is now XPASS for all powerpc
targets reported in the gcc-testresults archive.  It started passing for
powerpc64-unknown-linux-gnu with -m32 sometime between r139537 (2008-08-25) and
r139604 (2008-08-27).  This patch removes the xfail for that check.

The test fails for powerpc64-unknown-linux-gnu with -m64, so I left the
restriction that on powerpc*-*-* it it only run for ilp32.

------- Comment #9 from janis at gcc dot gnu dot org  2008-02-04 17:53 -------
It doesn't show up as FAIL for powerpc*-*-linux* becaues that check includes an
xfail:

  /* { dg-final { scan-assembler-not "LC\[0-9\]" { xfail powerpc*-*-* } } } */

Reopened.

I don't see this FAIL in any recently reported test results (on the
gcc-testresults mainling list) for powerpc-linux or powerpc64-linux.  Thus,
fixed.

Yes because AIX uses TOC, just like ppc64-linux so you will get LC for sure.

Does anyone know why we don't run this test at lp64 on powerpc? I find that on
powerpc-apple-darwin8 the following changes allow...

make check-gcc RUNTESTFLAGS="--target_board=unix'{-m32,-m64}'

to pass at both -m32 and -m64 on Darwin PPC...

As of mainline 20060417 the test is still failing on powerpc-linux, although it
passes for AIX and Darwin.  Until December 2005 when Alan fixed the target
specifier, the test had not been run on powerpc64-linux with -m32.
