Since this commit, I've noticed ICE on arm target:
FAIL: gcc.dg/params/blocksort-part.c -O3 --param prefetch-latency=0
(internal compiler error)
FAIL: gcc.dg/params/blocksort-part.c -O3 --param prefetch-latency=0
(test for excess errors)
Excess errors:
/aci-gcc-fsf/sources/gcc-fsf/gccsrc/gcc/testsuite/gcc.dg/params/blocksort-part.c:116:6:
internal compiler error: in duplicate
_ssa_name_ptr_info, at tree-ssanames.c:630

--target arm-none-linux-gnueabihf --with-cpu=cortex-a9
--wihth-fpu=neon-fp16 --with-mode=arm
I'm not sure the cpu/fpu/mode settings are mandatory but at least in this case
the compiler ICEs.
