Hi Kyrill,
I checked this patch on AMD seattle board and it bootstrapped cleanly with
BOOT_CFLAGS=-O2 -mcpu=native and CFLAGS_FOR_TARGET=-O2 -mcpu=native.
With -mcpu=cortex-57, I get
.cpu cortex-a57+fp+simd+crc
options passed: test.c -mcpu=cortex-a57 -mlittle-endian -mabi=lp64

This ICE is still in gfortran and with it the patch still current.
Bootstrapped and regtests ok on x86_64-linux-gnu/F21.
The patch has only changed in being applyable on current trunk (ct) w/o big
shifts.
Ok for trunk?

Hi,

it was best waiting for stage 1 to update you on this.

Hello!
This patch revives the old patch from Wei to merge movlpd/movsd with
movhpd to movupd. As evident from the patch, the patch merges only
instructions with simple memory references, which should IMO cover all
interesting cases (please see the included testcases).

If you just forward declare an enum/struct, it has an incomplete type, so you
cannot use it inside an aggregate.

This patch adds rtl patterns to generate bics instructions with shift.

Done full regression run on arm-none-eabi and arm-none-gnueabihf.

In vrp_visit_assignment_or_call we try to return SSA_PROP_VARYING

Another thing is that if update_value_range decides to
