Date: Thu, 17 Dec 2020 18:31:22 +0000 (GMT) [thread overview] Message-ID: <20201217183122.D80B23896C0F@sourceware.org> (raw) https://gcc.gnu.org/g:33ccbb506750cb14b2ac57b5a7c6f936c5ea1b6f commit 33ccbb506750cb14b2ac57b5a7c6f936c5ea1b6f Author: Michael Meissner <meissner@linux.ibm.com> Date: Thu Dec 17 13:30:11 2020 -0500 Revert patch. gcc/ 2020-12-17 Michael Meissner <meissner@linux.ibm.com> Revert. * config/rs6000/rs6000.c (rs6000_mangle_decl_assembler_name): Add support for mapping built-in function names for long double built-in functions if long double is IEEE 128-bit. gcc/testsuite/ 2020-12-17 Michael Meissner <meissner@linux.ibm.com> Revert. * gcc.target/powerpc/float128-longdouble-math.c: New test. * gcc.target/powerpc/float128-longdouble-stdio.c: New test. * gcc.target/powerpc/float128-math.c: Adjust test for new name being generated. Add support for running test on power10. Add support for running if long double defaults to 64-bits.
