[Bug target/22382] New: cris-axis-linux-gnu cross: gfortran.fortran-torture/execute/common.f90 -O2 host difference?

[hp at gcc dot gnu dot org]

With LAST_UPDATED "Thu Jun 30 14:21:26 UTC 2005",
gfortran.fortran-torture/execute/common.f90 fails:
FAIL: gfortran.fortran-torture/execute/common.f90 execution,  -O1
FAIL: gfortran.fortran-torture/execute/common.f90 execution,  -O2
FAIL: gfortran.fortran-torture/execute/common.f90 execution,  -O2
-fomit-frame-pointer -finline-functions
FAIL: gfortran.fortran-torture/execute/common.f90 execution,  -O2
-fno-repack-arrays
FAIL: gfortran.fortran-torture/execute/common.f90 execution,  -Os

whereas cross from i686-pc-linux-gnu with "Mon Jul  4 10:24:52 UTC 2005"
shows no fail for that case.  (Results from previous tests has been
flushed.)  In constrast, the "nearby" in-pack.f90 fails with -Os
on both hosts, regardless of -fpic:y options.

Lots of apples and oranges regarding source dates, but this is just
a public note that I need to investigate, particularly since (1) it
does not fail *at all* when adding (just) -fpic, (2) a target patch
will cause it to fail when -O2 -fpic.  It also fails baseline with
-mno-gotplt -fPIC and -mno-gotplt *without* -fpic/-fPIC!

Also marked "target" so nobody thinks I'm implying there's a bug elsewhere,
like in libgfortran.  I suspect a "64-bit bug" lurking somewhere.

For the record, random people wanting to repeat this, need to install
the glibc from cris-dist-1.62 (developer.axis.com, use the rpm, the dpkg,
or follow the instructions and gcc in that distribution to compile it)
and use --prefix=/usr/local/cris with the current tree to be able to repeat
the observations noted above.
