(Not a claim of a fix, just a reclassification.) = This is one of the bugs listed in "[Bug 25780] [META] Using Clang as the = FreeBSD/ppc system compiler" as known to be blocking the use of clang = for powerpc. With the recent addition of -mlongcall [llvm bug 19098 is now listed as = fixed on trunk], this may hint that some clang related work is = overlapping with what FreeBSD happens to need for powerpc64 and/or = powerpc. As no comments were added I'm not sure if it was looked at enough for my = original analysis of the code generated to have any independent = verification yet. Some of my original submittals got a cross check when = I submitted them and the comments reflect the process in such cases. = This one did not get such activity at the time or since. =3D=3D=3D Mark Millard markmi at dsl-only.net Begin forwarded message: From: bugzilla-daemon at llvm.org Subject: [Bug 26761] clang 3.8.0 messes up __builtin_dwarf_cfa (), at = least for TARGET_ARCH=3Dpowerpc and powerpc64 (gcc/g++ mismatch) Date: August 29, 2016 at 7:50:28 PM PDT To: Hal Finkel changed bug 26761=20 What Removed Added CC hfinkel at anl.gov Component LLVM Codegen Common Code Generator Code =20 Version 3.8 trunk Assignee unassignedclangbugs@nondot.org = unassignedbugs@nondot.org Product clang libraries You are receiving this mail because: =E2=80=A2 You reported the bug.
