aarch64: Fix matching of BRKNS
Unlike other flag-setting SVE instructions, BRKNS sets the flags
based on an all-true governing predicate, rather than the GP operand.
gcc/
* config/aarch64/iterators.md (SVE_BRKP): New iterator.
* config/aarch64/aarch64-sve.md (*aarch64_brkn_cc): New pattern.
(*aarch64_brkn_ptest): Likewise.
(*aarch64_brk<brk_op>_cc): Restrict to SVE_BRKP.
(*aarch64_brk<brk_op>_ptest): Likewise.
gcc/testsuite/
* gcc.target/aarch64/sve/acle/general/brkn_1.c: Expect separate
PTEST instructions.
* gcc.target/aarch64/sve/acle/general/brkn_2.c: New test.
