[Bug testsuite/40671] New: [4.5 Regression] internal compiler error: in extract_insn, at recog.c:2089 on powerpc

[dominiq at lps dot ens dot fr]

Probably due to revision 148869 the following tests fail on
powerpc-apple-darwin9 with -m32

FAIL: gcc.dg/vect/vect-82_64.c (internal compiler error)
FAIL: gcc.dg/vect/vect-83_64.c (internal compiler error)
FAIL: gcc.target/powerpc/darwin-misaligned.c (internal compiler error)
FAIL: gcc.target/powerpc/macho-lo-sum.c (internal compiler error)
FAIL: gcc.target/powerpc/ppc64-double-1.c (internal compiler error)
FAIL: gcc.target/powerpc/rs6000-fpint-2.c (internal compiler error)

See for instance http://gcc.gnu.org/ml/gcc-regression/2009-06/msg00188.html .

With -m64, only ppc64-double-1.c fails.

The failures are:

------- Comment #1 from meissner at gcc dot gnu dot org  2009-07-31 22:03 -------
I suspect this may be related to a problem with building for altivec that I
noticed after checking in the first of the powerpc changes.  If possible, could
you rebuild the compiler with BOOT_CFLAGS='-g -O2 -mno-altivec' to see if that
is the problem.

where I have edited the Makefile to add -mno-altivec to BOOT_CFLAGS and checked
that I saw it at stage 2 and 3, I still have the same errors.
