* config/mips/mips-protos.h (SYMBOL_FORCE_TO_MEM): Delete.
(SYMBOL_32_HIGH): Likewise.
(mips_output_tls_reloc_directive): Declare.
* config/mips/mips.h (PIC_FUNCTION_ADDR_REGNUM): Move to mips.md.
(mips_use_pcrel_pool_p, mips_lo_relocs, mips_hi_relocs): Declare.
* config/mips/mips.c (mips_use_pcrel_pool_p): New variable.
(mips_lo_relocs, mips_hi_relocs): Make extern.
(mips16_stub_function): Move up file.
(mips_classify_symbol): Remove SYMBOL_FORCE_TO_MEM handling.
(mips_symbolic_constant_p): Likewise. Remove SYMBOL_32_HIGH too.
(mips_symbol_insns_1): Likewise. Check mips_use_pcrel_pool_p.
(mips_cannot_force_const_mem): Use mips_use_pcrel_pool_p instead
of SYMBOL_FORCE_TO_MEM. Only check mips_tls_symbol_ref_1
if it's false.
(mips_get_tp): Add MIPS16 support.
(mips_legitimize_tls_address): Remove MIPS16 sorry().
Generalize DTPREL and TPREL handling.
(mips_init_relocs): Initialize mips_use_pcrel_pool_p.
Add MIPS16 TLS support.
(mips_output_tls_reloc_directive): New function.
(mips16_rewrite_pool_refs): Ignore UNSPEC_TLS_GET_TPs.
* config/mips/predicates.md (symbolic_operand_with_high)
(tls_reloc_operand): New predicates.
(force_to_mem_operand): Use mips_use_pcrel_pool_p.
* config/mips/mips.md (UNSPEC_UNSHIFTED_HIGH): New unspec.
(PIC_FUNCTION_ADDR_REGNUM): Moved from mips.h.
(*unshifted_high): New instruction. Use it for MIPS16
high splitter.
(consttable_tls_reloc, tls_get_tp_mips16_<mode>): New patterns.
(*tls_get_tp_mips16_call_<mode>): Likewise.
gcc/testsuite/
* gcc.target/mips/code-readable-2.c: Allow the jump table address
to be loaded from the constant pool, rather than via %hi and %lo.

* config/mips/libgcc-mips16.ver (__mips16_rdhwr): Add.
* config/mips/mips16.S (__mips16_rdhwr): New function.
* config/mips/t-mips16 (LIB1ASMFUNCS): Add _m16rdhwr.
