I'll sync them up. -- Brooks On Tue, Mar 17, 2015 at 08:02:47PM -0700, Mark Millard wrote: > patch-utils_llvm-build_llvmbuild_main.py is missing a powerpc64 entry, su= ch as illustrated below. >=20 > $ svnlite diff /usr/ports/lang/clang36 > Index: /usr/ports/lang/clang36/files/patch-utils_llvm-build_llvmbuild_mai= n.py > =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D > --- /usr/ports/lang/clang36/files/patch-utils_llvm-build_llvmbuild_main.p= y (revision 381120) > +++ /usr/ports/lang/clang36/files/patch-utils_llvm-build_llvmbuild_main.p= y (working copy) > @@ -3,7 +3,7 @@ > =20 > --- utils/llvm-build/llvmbuild/main.py.orig > +++ utils/llvm-build/llvmbuild/main.py > -@@ -633,7 +633,13 @@ > +@@ -633,7 +633,14 @@ > =20 > # We handle a few special cases of target names here for historical > # reasons, as these are the names configure currently comes up with. > @@ -13,6 +13,7 @@ > + 'i386' : 'X86', > + 'mips' : 'Mips', > + 'powerpc' : 'PowerPC', > ++ 'powerpc64' : 'PowerPC', > + 'sparc64' : 'Sparc', > + 'x86' : 'X86', > 'x86_64' : 'X86', >=20 >=20 > =3D=3D=3D > Mark Millard > markmi at dsl-only.net >=20 > On 2015-Mar-16, at 11:00 PM, Mark Millard <markmi at dsl-only.net> wrote: >=20 > The 2 powerpc (non-64) build attempts for clang 3.6 did not get this prob= lem. >=20 > So this specific problem is powerpc64 specific. >=20 > Bootstrapping powerpc (non-64) clang 3.6 via gcc 4.8.4 (the current lang/= gcc) works fine.
