            Bug ID: 61548

           Product: gcc

On arm and aarch64 I see ICEs in the aforementioned test:

$TOP/gcc/testsuite/gcc.dg/tls/alias-1.c:24:3: internal compiler error:

I'm using an arm-none-eabi cross configured with --with-fpu=neon-fp-armv8
--with-arch=armv8-a at r211767.

Trying to go back to find a good revision is not easy because arm builds have
been broken by other things recently.
