--- Comment #1 from Uros Bizjak <ubizjak at gmail dot com> 2011-11-07 16:24:28 UTC --- The problem is in (call:DI (mem:QI (symbol_ref:DI ("__tls_get_addr")) [0 S1 A8]), the symbol_ref does not satisfy constant_call_address_operand predicate. Unfortunately, these are specified sequences, so all we can do is to declare large PIC code model incompatible with GNU TLS dialect.
