The original code did not support dynamically loaded libraries and used suboptimal access to TLS variables. New implementation removes lazy resolving of TLS relocation - due to flaw in TLSDESC design is impossible to switch resolver function at runtime without expensive locking. Due to this, 3 specialized resolvers are implemented: - load time resolver for TLS relocation from libraries loaded with main executable (thus with known TLS offset). - resolver for undefined thread weak symbols. - slower lazy resolver for dynamically loaded libraries with fast path for already resolved symbols.
