[Bug c++/37909] New: internal compiler error: in fixup_mova, at config/sh/sh.c:3756

[masaki dot chikama at gmail dot com]

I got internal compile error when compiling vtk.
The flowing ccPOF0j6.cxx is preprocessed file while compiling with sh4 native
gcc.
Then I confirm it using gcc-4_3_branch cross compiler.

$ ~/x-tools/sh4-unknown-linux-gnu/bin/sh4-unknown-linux-gnu-gcc -g -O2 -fPIC
ccPOF0j6.cxx 
/builddir/build/BUILD/VTK/Rendering/vtkFreeTypeUtilities.cxx: In function 'int
vtkFreeTypeUtilitiesRenderString(vtkFreeTypeUtilities*, vtkTextProperty*, const
char*, int, int, vtkImageData*, T*, int) [with T =
vtkFreeTypeUtilities::RenderString::VTK_TT]':
/builddir/build/BUILD/VTK/Rendering/vtkFreeTypeUtilities.cxx:1190: internal
compiler error: in fixup_mova, at config/sh/sh.c:3756
Please submit a full bug report,
with preprocessed source if appropriate.

I've confirmed that it fails on the trunk and the reduced test
case fails on 4.2.4.

sh_reorg might insert a new mova in SH_FIXUP_PCLOAD phase.
When untangle_mova looks this mova insn, it may not be associated
with the insn address yet but the current code takes its undefined
address.  It seems that this mova should be skipped there because
it will be handled later.  I'm testing the attached patch.
