Hi,
The problem appears in revision 201034 in version 4.9. I attached
one-line patches that fixes it. I also reported this problem
at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57811
Bootstrap and regression-tested on x86_64-linux.
In method "find_reloads()" in gcc/reload.c, the loop on line 3324 should
break immediately after "badop" is set to "1". Also, the loop on line 4641
should break after "ok" is set to "0".

* reload.c (find_reloads): Exit loop once we find this operand
cannot be reloaded somehow for this alternative.
* reload.c (find_reloads): Exit loop once we find a
hard register.
Thanks. Installed.
