--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alexandre Oliva <aol...@gcc.gnu.org>: https://gcc.gnu.org/g:dbdddc92a3b955fce71af47755c226132559eda2 commit r15-786-gdbdddc92a3b955fce71af47755c226132559eda2 Author: Alexandre Oliva <ol...@adacore.com> Date: Thu May 23 03:20:19 2024 -0300 [testsuite] xfail pr79004 on longdouble64; drop long_double_64bit Some of the asm opcodes expected by pr79004 depend on -mlong-double-128 to be output. E.g., without this flag, the conditions of patterns @extenddf<mode>2 and extendsf<mode>2 do not hold, and so GCC resorts to libcalls instead of even trying rs6000_expand_float128_convert. Perhaps the conditions are too strict, and they could enable the use of conversion insns involving __ieee128/_Float128 even with 64-bit long doubles. For now, xfail the opcodes that are not available on longdouble64. While at that, drop long_double_64bit, since it's broken and sort of redundant. for gcc/testsuite/ChangeLog PR target/105359 * gcc.target/powerpc/pr79004.c: Xfail opcodes not available on longdouble64. * lib/target-supports.exp (check_effective_target_long_double_64bit): Drop. (add_options_for_long_double_64bit): Likewise.
