--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The problem is that adjust_address with
(mem/c:TI (const:DI (unspec:DI [
(symbol_ref:DI ("s") [flags 0x2a] <var_decl 0x7ffff7ffbb40 s>)
] UNSPEC_NTPOFF)) [1 s+0 S16 A64 AS1])
as first argument, E_DImode and 8 as last two doesn't validate.
We have originally:
(insn 7 6 10 2 (set (mem/c:TI (plus:DI (unspec:DI [
(const_int 0 [0])
] UNSPEC_TP)
(const:DI (unspec:DI [
(symbol_ref:DI ("s") [flags 0x2a] <var_decl
0x7ff97a130b40 s>)
] UNSPEC_NTPOFF))) [1 s+0 S16 A64])
(reg:TI 83)) "pr89290.c":7:5 65 {*movti_internal}
(nil))
then the ix86_rewrite_tls_address splitter rewrites this into:
(insn 12 6 10 2 (set (mem/c:TI (const:DI (unspec:DI [
(symbol_ref:DI ("s") [flags 0x2a] <var_decl
0x7ff97a130b40 s>)
] UNSPEC_NTPOFF)) [1 s+0 S16 A64 AS1])
(reg:TI 83)) "pr89290.c":7:5 -1
(nil))
and finally we ICE in the split_double_move splitter.
