------- Comment #9 from uweigand at gcc dot gnu dot org 2006-01-30 18:32 ------- This appears to be a pre-existing bug in s390_decompose_address, that happens to be triggered by this particular glibc code.
The problem is the construct &&label1 - &&label2 used in the source (b.t.w. is this usage of the GCC &&label extension valid in the first place?), which causes GCSE to generate RTL of the form (minus (label_ref ..) (label_ref ..)) s390_decompose_address accepts those, because I thought the only time this construct could ever be generated is from within the s390 machine-dependent reorg code ... I'm currently testing a fix. -- uweigand at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |uweigand at gcc dot gnu dot |dot org |org Status|UNCONFIRMED |ASSIGNED Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2006-01-30 18:32:04 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26018
