g++.dg/other/pr53811.C fails on x86_64-apple-darwin10 with -m64:
FAIL: g++.dg/other/pr53811.C -std=gnu++98 (internal compiler error)
FAIL: g++.dg/other/pr53811.C -std=gnu++98 (test for excess errors)
FAIL: g++.dg/other/pr53811.C -std=gnu++11 (internal compiler error)
FAIL: g++.dg/other/pr53811.C -std=gnu++11 (test for excess errors)
The ICE is
Excess errors:
/opt/gcc/work/gcc/testsuite/g++.dg/other/pr53811.C:29:1: error: insn does not
satisfy its constraints:
(insn 3 2 4 (set (reg:DI 59)
(const:DI (unspec:DI [
(symbol_ref:DI ("_ZN12ScriptString12CreateStringEPKc")
[flags 0x403] <function_decl 0x142987100 CreateString>)
] UNSPEC_GOTOFF))) 62 {*movdi_internal_rex64}
(nil))
Should I open a new PR?
Note that ' -mcmodel=large' seems to have issues on x86_64-apple-darwin10: see
pr50077.
