Thanks, here is the updated version, with the initialization of labelno in
call_tls_get_addr moved from patch 4/21.

commit 481d4161a6cdf88091cd2fef7ee7fe6b8a836d18
Author: Christophe Lyon <christophe.lyon@linaro.org>
Date: Thu Feb 8 14:42:05 2018 +0100
[ARM] FDPIC: Implement TLS support.
Support additional relocations: TLS_GD32_FDPIC, TLS_LDM32_FDPIC, and
TLS_IE32_FDPIC.
We do not support the GNU2 TLS dialect.
2019-XX-XX Christophe Lyon <christophe.lyon@st.com>
Mickaël Guêné <mickael.guene@st.com>
gcc/
* config/arm/arm.c (tls_reloc): Add TLS_GD32_FDPIC,
TLS_LDM32_FDPIC and TLS_IE32_FDPIC.
(arm_call_tls_get_addr): Add FDPIC support.
(legitimize_tls_address): Likewise.
(arm_emit_tls_decoration): Likewise.
