-O2 -fpie -mtls-direct-seg-refs -m32 works OK, compiler goes through the same
code paths as in 64bit case:
(insn 18 17 19 2 (set (reg:SI 3 bx [ cache+4 ])
(mem/u/c:SI (const:SI (plus:SI (unspec:SI [
(symbol_ref:SI ("_ZZ7tempDirvE5cache") [flags
0x2a])
] UNSPEC_NTPOFF)
(const_int 4 [0x4]))) [1 cache+4 S4 A32 AS2]))
resulting in:
movl %gs:_ZZ7tempDirvE5cache@ntpoff, %ecx
movl 8(%esp), %eax
movl %gs:4+_ZZ7tempDirvE5cache@ntpoff, %ebx
movl %ecx, (%eax)
movl %ebx, 4(%eax)
It looks to me that 64bit x86_64 should also accept UNSPEC_NTPOFF symbol
references with a small offset.
