             Bug #: 14716
           Summary: libtool: link messes up '-mllvm -vectorize' to '-mllvm
                    -Wl,...'

           Version: trunk

Yes, it is actually a libtool issue but in the meantime clang should be able to
handle this.

/bin/sh ../../../libtool  --tag=CC   --mode=link clang -fvisibility=hidden
-Wall -std=c99 -Werror=implicit-function-declaration -Werror=missing-prototypes
-fno-strict-aliasing -fno-builtin-memcmp -g -O0 -fmessage-length=0 -O2 -Wall
-D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables

-no-undefined  -o libOpenVG.la -rpath /usr/lib64 entry.lo mapi.lo stub.lo

libtool: link: clang -shared  -fPIC -DPIC  .libs/entry.o .libs/mapi.o

-O2 -mllvm   -Wl,-soname -Wl,libOpenVG.so.1 -o .libs/libOpenVG.so.1.0.0

clang-3: warning: argument unused during compilation: '-mllvm -Wl,-soname'

/usr/bin/ld: cannot find libOpenVG.so.1: No such file or directory

clang-3: error: linker command failed with exit code 1 (use -v to see
invocation)


Manually invoking it works (s:-mllvm:-mllvm -vectorize):
clang -shared  -fPIC -DPIC  .libs/entry.o .libs/mapi.o .libs/stub.o
.libs/table.o .libs/u_current.o .libs/u_execmem.o   -lpthread  -O0 -O2 -mllvm
-vectorize  -Wl,-soname -Wl,libOpenVG.so.1 -o .libs/libOpenVG.so.1.0.0

clang-3: warning: argument unused during compilation: '-mllvm -vectorize'
