S/390: arch12: New builtins.
This patch implements a set of low-level builtins for instruction which would otherwise not be emitted by the compiler plus a set of high-level builtins as defined by the IBM XL compiler. The high-level builtins will be described in a future revision of the z/OS XL C/C++ Programming Guide. I'll try to come up with a documentation appropriate for the GCC manual as well (sometimes in the future). gcc/ChangeLog: 2017-03-24 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/s390/s390-builtins.def: Add VXE builtins. Add a flags argument to the overloaded builtin variants. Use the new flag to deprecate certain builtin variants. * config/s390/s390-builtin-types.def: Add new builtin types. * config/s390/s390-builtins.h: Support new flags field for overloaded builtins. * config/s390/s390-c.c (OB_DEF_VAR): New flags field. (s390_macro_to_expand): Enable vector float data type. (s390_cpu_cpp_builtins_internal): Indicate support of the new builtins by incrementing the __VEC__ version number. (s390_expand_overloaded_builtin): Support expansion of vec_xl and vec_xst. (s390_resolve_overloaded_builtin): Emit error messages depending on the builtin flags. * config/s390/s390.c (s390_expand_builtin): Support additional flags argument. Change error message to match the messages emitted in s390-c.c. * config/s390/s390.md: New UNSPEC_* constants. (op_type): Add new instruction types. * config/s390/vecintrin.h: Add new builtins and test data class constants. * config/s390/vx-builtins.md (V_HW_32_64): Add V4SF. (V_HW_4, VEC_HW, VECF_HW): New mode iterators. (VEC_INEXACT, VEC_NOINEXACT): New constants. ("vec_splats<mode>", "vec_insert<mode>", "vec_promote<mode>") ("vec_insert_and_zero<mode>", "vec_mergeh<mode>") ("vec_mergel<mode>"): V_HW -> VEC_HW.

("vec_ctd_s64", "vec_ctsl", "vec_ctul", "vec_st2f"): Use rounding mode constant instead of magic value. gcc/testsuite/ChangeLog: 2017-03-24 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * gcc.target/s390/target-attribute/tattr-3.c: Adjust error message and remove the high-level builtin. The error message for the would prevent compilation from reaching the second. * gcc.target/s390/target-attribute/tattr-4.c: Likewise. From-SVN: r246459
