[gcc] 2017-11-14 Michael Meissner <meissner@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. (truncf128_round_to_odd): Likewise. (addf128_round_to_odd): Likewise. (subf128_round_to_odd): Likewise. (mulf128_round_to_odd): Likewise. (divf128_round_to_odd): Likewise. (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. [gcc/testsuite] 2017-11-14 Michael Meissner <meissner@linux.vnet.ibm.com> * gcc.target/powerpc/float128-hw4.c: New test. From-SVN: r254740
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
