            Status: UNCONFIRMED

GCC ICEed with shrink-wrap-sibcall.c on a15 with below command line:
./arm-none-eabi-gcc -O2 -marm -mcpu=cortex-a15 -mfpu=neon -mfloat-abi=hard
shrink-wrap-sibcall.c -S -o shrink-wrap-sibcall.S -fno-diagnostics-show-caret
-fdiagnostics-color=never -O2 -g

ICE msg is:

how it is configured for arm.

--- Comment #1 from zhenqiang.chen at linaro dot org ---
Root cause:
RTX_FRAME_RELATED_P is not correctly set in function arm_emit_ldrd_pop.

I will create a patch to fix it.
