v3 -> v4:
1. Add macro support for TLS symbols
2. Added support for loading __get_tls_addr symbol address using call36.
3. Merge template got_load_tls_{ld/gd/le/ie}.
4. Enable explicit reloc for extreme TLS GD/LD with -mexplicit-relocs=auto.
I've rebased and attached the patch to fix the bad split in -mexplicit-
relocs={always,auto} -mcmodel=extreme on top of this series. I've not
tested it seriously though (only tested the added and modified test
cases).
OK, I'll test the spec for correctness.
I suppose this still won't work yet because Binutils is not fully fixed.
GAS has been changed not to emit R_LARCH_RELAX for "la.tls.ie a0, t0,
foo", but ld is still not checking if an R_LARCH_RELAX is after
R_LARCH_TLS_IE_PC_{HI20,LO12} properly. Thus an invalid "partial" TLS
transition can still happen.
I temporarily changed my binutils to turn off this function.;-)
