Severity: normal
Tags: upstream patch
Whenever gccgo is used via the /usr/bin/go command, it calls "ar cru ...",
which causes this warning:
$ go build -compiler=gccgo
# github.com/ecc1/primes
ar: `u' modifier ignored since `D' is the default (see `U')
Details:
$ go build -x -compiler=gccgo
WORK=/tmp/go-build529072590
mkdir -p $WORK/github.com/ecc1/primes/_obj/
mkdir -p $WORK/github.com/ecc1/primes/_obj/exe/
cd /home/ecc/go/src/github.com/ecc1/primes
/usr/bin/gccgo -I $WORK -c -g -m64
-fgo-relative-import-path=_/home/ecc/go/src/github.com/ecc1/primes -o

# github.com/ecc1/primes
ar: `u' modifier ignored since `D' is the default (see `U')
cd .
/usr/bin/gccgo -o $WORK/github.com/ecc1/primes/_obj/exe/a.out
$WORK/github.com/ecc1/primes/_obj/_go_.o -Wl,-( -m64 -Wl,-)
mv $WORK/github.com/ecc1/primes/_obj/exe/a.out primes
The attached patch simply uses "ar cr" instead. The extra I/O for
unchanged archive members is probably negligible.
