--- Comment #4 from Michael Meissner <meissner at gcc dot gnu.org> --- Author: meissner Date: Thu Nov 16 20:29:52 2017 New Revision: 254846 URL: https://gcc.gnu.org/viewcvs?rev=254846&root=gcc&view=rev Log: [gcc] 2017-11-16 Michael Meissner <meiss...@linux.vnet.ibm.com> Back port from trunk 2017-11-16 Michael Meissner <meiss...@linux.vnet.ibm.com> * config/rs6000/rs6000.c (rs6000_expand_builtin): Do not do the switch statement mapping KF built-ins to TF built-ins if we don't have the proper ISA 3.0 assembler support. Back port from trunk 2017-11-14 Michael Meissner <meiss...@linux.vnet.ibm.com> * config/rs6000/rs6000-c.c (is_float128_p): New helper function. (rs6000_builtin_type_compatible): Treat _Float128 and long double as being compatible if -mabi=ieeelongdouble. * config/rs6000/rs6000-builtin.def (BU_FLOAT128_HW_1): New macros to setup float128 built-ins with hardware support. (BU_FLOAT128_HW_2): Likewise. (BU_FLOAT128_HW_3): Likewise. (BU_FLOAT128_HW_VSX_1): Likewise. (BU_FLOAT128_HW_VSX_2): Likewise. (scalar_extract_expq): Change float128 built-in functions to accommodate having both KFmode and TFmode functions. Use the KFmode variant as the default. (scalar_extract_sigq): Likewise. (scalar_test_neg_qp): Likewise. (scalar_insert_exp_q): Likewise. (scalar_insert_exp_qp): Likewise. (scalar_test_data_class_qp): Likewise. (sqrtf128_round_to_odd): Delete processing the round to odd built-in functions as special built-in functions, and define them as float128 built-ins. Use the KFmode variant as the default.

(fmaf128_round_to_odd): Likewise. * config/rs6000/rs6000.c (rs6000_expand_binop_builtin): Add support for KFmode and TFmode xststdcqp calls. (rs6000_expand_builtin): If long double is IEEE 128-bit floating point, switch the built-in handlers for the get/set float128 exponent, get float128 mantissa, float128 test built-ins, and the float128 round to odd built-in functions. Eliminate creating the float128 round to odd built-in functions as special built-ins. (rs6000_init_builtins): Eliminate special creation of the float128 round to odd built-in functions. * config/rs6000/vsx.md (xsxexpqp_<mode>): Change float128 built-in function insns to support both TFmode and KFmode variants. (xsxsigqp_<mode>): Likewise. (xsiexpqpf_<mode>): Likewise. (xsiexpqp_<mode>): Likewise. (xststdcqp_<mode>): Likewise. (xststdcnegqp_<mode>): Likewise. (xststdcqp_<mode>): Likewise.

(BU_FLOAT128_2): Likewise. (BU_FLOAT128_1_HW): Likewise. (BU_FLOAT128_2_HW): Likewise. (BU_FLOAT128_3_HW): Likewise. (FABSQ): Delete old 'q' built-in functions. (COPYSIGNQ): Likewise.

(FMAF128_ODD): Likewise. * config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Map old 'q' built-in names to 'f128'. * config/rs6000/rs6000.c (rs6000_fold_builtin): Remove folding the old 'q' built-in functions, as the machine independent code for 'f128' built-in functions handles this. (rs6000_expand_builtin): Add expansion for float128 round to odd functions, keying off on -mabi=ieeelongdouble of whether to use the KFmode or TFmode variant. (rs6000_init_builtins): Initialize the _Float128 round to odd built-in functions. * doc/extend.texi (PowerPC Built-in Functions): Document the old _Float128 'q' built-in functions are now mapped into the new 'f128' built-in functions.
