gcc/
- config/mips/mips-protos.h (mips_set_text_contents_type): New prototype.
- config/mips/mips.h (ASM_OUTPUT_BEFORE_CASE_LABEL): New macro. (ASM_OUTPUT_CASE_END): Likewise.
- config/mips/mips.c (mips_set_text_contents_type): New function. (mips16_emit_constants): Record the pool's initial label number with the `consttable' insn. Emit a `consttable_end' insn at the end. (mips_final_prescan_insn): Call `mips_set_text_contents_type' for `consttable' insns. (mips_final_postscan_insn): Call `mips_set_text_contents_type' for `consttable_end' insns.
- config/mips/mips.md (unspec): Add UNSPEC_CONSTTABLE_END enum
value. (consttable): Add operand. (consttable_end): New insn.

gcc/testsuite/
- gcc.target/mips/data-sym-jump.c: New test case.
