Hi maxim
I want to compile odp for AMRMv6j with toolchain having gcc version 4.3.3,. I
getting the following issue .
1. Compilation fails for ARMv6j with toolchain having gcc version 4.3.3:
a. Undefined reference to __sync_fetch_and_sub_4/__sync_fetch_and_add_8/
__sync_lock_test_and_set_4/ __sync_fetch_and_sub_4/ __sync_fetch_and_sub_8 (all
sync built-in functions). As the sync functions support was provided in gcc
4.4+ versions
b. Undefined reference to `__aeabi_read_tp' - This issues comes due to the
presence of __thread specifier
Compilation logs:

We have constraints moving to newer version of gcc so can you provide guidance
in this respect.
