PR target/51931
* config/mips/mips-protos.h (mips_strip_unspec_address): Declare.
* config/mips/mips.c (mips_strip_unspec_address): Make extern.
(mips16_rewrite_pool_constant): Make a copy of the pool constant
before adding to a PC-relative table.
(mips16_lay_out_constants): Add a SPLIT_P parameter.
(mips16_load_branch_target, mips16_split_long_branches): New functions.
(mips_reorg): Update call to mips16_lay_out_constants.
Call mips16_split_long_branches.
* config/mips/predicates.md (pc_or_label_operand): Delete.
* config/mips/mips.md (length): Add a calculation for MIPS16 branches.
Move the extended_mips16 handling further down.
(*branch_equality<mode>_mips16): Replace use pc_or_label_operand
with explicit label_ref and pc. Follow the usual operand numbering.
(*branch_equality<mode>_mips16_inverted): New pattern.
(*jump_mips16): Add length attribute.
(indirect_jump_and_restore_<mode>): New pattern.
(consttable_int): Call mips_strip_unspec_address on the operand.
