[gcc] 2017-11-06 Michael Meissner <meissner@linux.vnet.ibm.com> PR target/82748 * config/rs6000/rs6000-builtin.def (BU_FLOAT128_1): Delete float128 helper macros, which are no longer used after deleting the old 'q' built-in functions, and moving the round to odd built-in functions to being special built-in functions. (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. (SQRTF128_ODD): Move round to odd built-in functions to be special built-in functions, so that we can handle -mabi=ieeelongdouble. (TRUNCF128_ODD): Likewise. (ADDF128_ODD): Likewise. (SUBF128_ODD): Likewise. (MULF128_ODD): Likewise. (DIVF128_ODD): 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.

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.
