https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207736 --- Comment #2 from Mark Millard <markmi@dsl-only.net> --- As of clang 3.9.1 TARGET_ARCH=3Dpowerpc still has some R31 restoration problems when floating point code is also involved: R31 is restored but later floating-point cleanup code is based on R31 not having been restored yet. In other words: R31 is restored too early. This is not specific to _Unwind_RaiseException . --=20 You are receiving this mail because: You are the assignee for the bug.=
