--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:0069ce6631880776a44fb8408c6428c0812285cf commit r12-9526-g0069ce6631880776a44fb8408c6428c0812285cf Author: Dan Horák <d...@danny.cz> Date: Wed May 3 14:29:09 2023 -0500 libffi: fix handling of homogeneous float128 structs (#689) If there is a homogeneous struct with float128 members, they should be copied to vector register save area. The current code incorrectly copies only the value of the first member, not increasing the pointer with each iteration. Fix this. Merged from upstream libffi commit: 464b4b66e3cf3b5489e730c1466ee1bf825560e0 2023-05-03 Dan Horák <d...@danny.cz> libffi/ PR libffi/109447 * src/powerpc/ffi_linux64.c (ffi_prep_args64): Update arg.f128 pointer.
