(powerpc64 already has "red-zone" use because that is part of the powerpc64 ABI used by FreeBSD.) https://llvm.org/bugs/show_bug.cgi?id=3D26519 Some parts of the following item apply to more general code generation cont= exts than just exception-handling, although it started with finding exception-handling examples. https://llvm.org/bugs/show_bug.cgi?id=3D26856 The below 2 are for exception-handling code generation issues (counting .eh_frame information as code). https://llvm.org/bugs/show_bug.cgi?id=3D26761 https://llvm.org/bugs/show_bug.cgi?id=3D26844 The 1 item below was fixed in 3.8.0 rc3 but not in rc2 or earlier versions. https://llvm.org/bugs/show_bug.cgi?id=3D26605 (All these submittals to llvm.org came from attempting to use clang 3.8.0 f= or TARGET_ARCH=3Dpowerpc buildworld on an old PowerMac.
