Previously GCC created built-in declarations for doing long double complex +multiply and divide when long double is IEEE 128-bit. However, it did not +support __ibm128 complex multiply and divide if long double is IEEE 128-bit. + +This code does not create the built-in declaration with the changed name. +Instead, it uses the TARGET_MANGLE_DECL_ASSEMBLER_NAME hook to change the name +before it is written out to the assembler file like it now does for all of the +other long double built-in functions. + +2023-03-08 Michael Meissner <meissner@linux.ibm.com> + +gcc/ + + PR target/109067 + * config/rs6000/rs6000.cc (create_complex_muldiv): Delete. + (init_float128_ieee): Delete code to switch complex multiply and divide + for long double. + (complex_multiply_builtin_code): New helper function. + (complex_divide_builtin_code): Likewise. + (rs6000_mangle_decl_assembler_name): Add support for mangling the name + of complex 128-bit multiply and divide built-in functions. + +gcc/testsuite/ + + PR target/109067 + * gcc.target/powerpc/divic3-1.c: New test. + * gcc.target/powerpc/divic3-2.c: Likewise. + * gcc.target/powerpc/mulic3-1.c: Likewise. + * gcc.target/powerpc/mulic3-2.c: Likewise. + +==================== Branch work110, baseline ==================== + 2023-03-06 Michael Meissner <meissner@linux.ibm.com> Clone branch
