Hello all,

My go version is 1.7.1.

My env variable is listed in the following:
export GOROOT=~/go
export GOOS=linux
export GOARCH=arm
export CC=/usr/local/arm-linux/bin/gcc
export CXX=/usr/local/arm-linux/bin/g++
export GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
build829110422=/tmp/go-build -gno-record-gcc-switches"
export CGO_ENABLED=1

I wanted to cross compile a go program but the following was returned:

go build
:
:

runtime/cgo

../../go/src/runtime/cgo/gcc_arm.S: Assembler messages:
../../go/src/runtime/cgo/gcc_arm.S:27: Error: bad instruction push {r4,r5,r6,r7,r8,r9,r10,r11,ip,lr}' ../../go/src/runtime/cgo/gcc_arm.S:37: Error: bad instructionpop {r4,r5,r6,r7,r8,r9,r10,r11,ip,pc}'

I checked the ../../go/src/runtime/cgo/gcc_arm.S file and it does exist but why it contains bad instructions?

BR,
Terry

What compiler and assembler do you have installed (cc --version, as --version)?

Show us the output of go build -x.

ubuntu@ubuntu:~$ /usr/local/arm-linux/bin/gcc --version
gcc (GCC) 3.2.1

ubuntu@ubuntu:~$ /usr/local/arm-linux/bin/as --version
GNU assembler 2.13.2

go build -x can build successfully. But the file output is of type x86, not arm.

We believe gcc 4.x will fix this. If not, please file a new issue. Thanks.
