------- Comment #9 from matz at gcc dot gnu dot org 2009-06-03 15:57 ------- Bah, simply not expanding those variables (whose SSA partitions were already) by clearing TREE_USED on them fixes the problem, but makes those variables have no debug info at all, as the DECLs then have no DECL_RTL_SET anymore.
Which indeed we can't easily use in case one base variable got split into several SSA partitions: we have several places but only one DECL. This is no problem in -g -O0 mode, so I can hack around this. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40012
