--- Comment #4 from Christophe Lyon <clyon at gcc dot gnu.org> ---
I have updated the test in the initial description to call intrinsics, added
relevant dg-* directives. Testing with several configurations under progress.
Is it really r11-6708 that introduced the problem? It doesn't modify vshq
unlike it's predecessor r11-6707-g7432f255b70811dafaf325d94036ac580891de69.
And that one only moves the offending pattern from neon.md to vec-common.md, so
the bug was probably already present?
As of -mtune=generic-armv7-a, I can reproduce the ICE with
-mcpu=generic-armv7-a, but I haven't found a -march equivalent
(-march=armv7-a+fp does not trigger the ICE)
