This patch replaces (const_int 0) in vector patterns with its
const_vector representation. Backported to 4.7 and 4.8.
* config/tilegx/tilegx.md (insn_mnz_<mode>): Replaced by ...
(insn_mnz_v8qi): ... this ...
(insn_mnz_v4hi): ... and this. Replace (const_int 0) with the
vector equivalent.
(insn_v<n>mnz): Replaced by ...
(insn_v1mnz): ... this ...
(insn_v2mnz): ... and this. Replace (const_int 0) with the vector
equivalent.
(insn_mz_<mode>): Replaced by ...
(insn_mz_v8qi): ... this ...
(insn_mz_v4hi): ... and this. Replace (const_int 0) with the
vector equivalent.
(insn_v<n>mz): Replaced by ...
(insn_v1mz): ... this ...
(insn_v2mz): ... and this. Replace (const_int 0) with the vector
equivalent.
