  "message": "PowerPC: Add support for IEEE 128-bit format.\n\nThe test gdb.base/infcall-nested-structs-c.exp fails on a gdb assert\nin function ppc64_sysv_abi_return_value in file gdb/ppc-sysv-tdep.c.  The\nassert is due to the missing IEEE 128-bit support in file\ngdb/ppc-sysv-tdep.c.\n\nThe IBM long double was the initial float 128-bit support added by IBM\nThe IEEE 128-bit support, which is similar IBM long double support, was\nmade the default starting with GCC 12.  The floating point format\ndifferences include the number of bits used to encode the exponent\nand significand.  Also, IBM long double values are passed in a pair of\nfloating point registers.  The  IEEE 128-bit value is passed in a single\nvector register.\n\nThis patch fixes the gdb_assert (ok); in function\nppc64_sysv_abi_return_value in gdb/ppc-sysv-tdep.c by adding IEEE FLOAT\n128-bit type support for PowerPC.\n\nThe patch has been tested on Power 10, ELFv2.  It fixes the following list\nof regression failures on Power 10:\n\ngdb.base/infcall-nested-structs-c.exp      192\ngdb.base/infcall-nested-structs-c++.exp     76\ngdb.base/structs.exp                         9\n\nThe patch has been tested on Power 8 BE which is ELFv1.\n",
