            Bug ID: 20047
           Summary: The arc assembler outputs an "unrecognized option"
                    error with a weird character in it
           Product: binutils
           Version: 2.26
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: dhowells at redhat dot com
  Target Milestone: ---

Running the arc assembler produces an error with a weird character in it:

echo | /data/fedora/cross-gcc/gcc-6.1.1-20160427/arc-linux-gnu/./gcc/as -v
-mARC700 -mEA -o conftest.o 
GNU assembler version 2.26 (arc-linux-uclibc) using BFD version version
2.26.20160125
Assembler messages:
Error: unrecognized option -Î

It appears that it doesn't like the -mEA argument supplied by gcc, but gets the
error message wrong.

The version was binutils-2.26. The configuration was:

LDFLAGS='-Wl,-z,relro ' \
../binutils-2.26/configure --disable-dependency-tracking --disable-silent-rules
--enable-checking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin
--sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share
--includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec
--localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man
