Well, an LRA ICE is unlikely caused by this change. It must be a latent issue
instead.

Probably, since the build succeeded at rev 211303.

Since commit 211625:
2014-06-13 Richard Biener <rguenther@suse.de>
* tree-ssa-pre.c (eliminate_dom_walker::before_dom_children):
Rewrite to propagate the VN result into all uses where
possible and to remove stmts becoming dead because of that.
(eliminate): Generalize stmt removal handling, remove in
reverse dominator order to support proper debug stmt
generation. Update stmts before removing stmts.
* tree-ssa-propagate.c (propagate_tree_value): Remove
bogus assert.
The same error now appears when building other GCC configurations:
--target mode --with-cpu --with-fpu
arm-none-linux-gnueabi arm cortex-a9 default
arm-none-linux-gnueabihf arm cortex-a9 neon-fp16
arm-none-linux-gnueabihf arm cortex-a9 vfp
arm-none-linux-gnueabihf arm cortex-a15 neon-vfpv4
armeb-none-linux-gnueabihf arm cortex-a9 neon-fp16
Vladimir, can you have a look?

This looks like:
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg00971.html
Which has been approved by Vladimir. I guess if I don't hear anything from
Chung-Lin in the next few hours I'll commit this on their behalf.
