Unless you can soon manage to fix both at once with a single patch, maybe
better separating the PRs again. Anyway, with your draft,

The vldX and vstX variation of NEON intrinsics, where X 1, seem to cause the

}

The binutils patch that broke libjava came from CodeSourcery, so I decided to
test their latest G++ lite for arm-linux-gnueabi (2009q3-67). That compiler is
based on gcc-4.4.1, and it does not have the libjava

I'm using the stock Fedora 12 gcc, RPM gcc-4.4.3-4.fc12.x86_64.
Whereas it appears to align __m128 variables correctly (16-bytes), it accesses
them as if they were only 8 byte aligned.
I read various threads etc about aligning variables on the stack, but my belief
is that this never was a problem

This is not an uninitialized issue.
The reason this requires -O2 is that -Warray-bounds requires VRP to warn. The
gimple output already looks quite different.
