--- Comment #6 from Mikael Pettersson <mikpe at it dot uu.se> 2011-02-01 10:11:52 UTC --- The bug started to occur at r140501: Author: pinskia Date: Fri Sep 19 22:24:06 2008 New Revision: 140501 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=140501 Log: 2008-09-19 Andrew Pinski <andrew_pin...@playstation.sony.com> PR tree-opt/30930 * tree-ssa.c (execute_update_addresses_taken): Also update DECL_GIMPLE_REG_P for vector and complex types. But given Ian's observation and proposed patch I suspect r140501 is innocent and merely triggers a bug in the ARM backend.
