Tests fail on armel (little-endian ARM)

[oerdnj]

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Build on armel and run test

What is the expected output?
ok sync/atomic

What do you see instead?
SIGILL: illegal instruction
PC=0xc233c

Which compiler are you using (5g, 6g, 8g, gccgo)?
5g

Which operating system are you using?
armel (Little-endian ARM, e.g. GOARM=5)

Which version are you using?  (run 'go version')
go1

Please provide any additional information below.
The build variables are set using this logic:

ifeq ($(DEB_HOST_ARCH_CPU), i386)
    GOARCH := 386
    GOPREFIX := 8
else ifeq ($(DEB_HOST_ARCH_CPU), amd64)
    GOARCH := amd64
    GOPREFIX := 6
else ifeq ($(DEB_HOST_ARCH_CPU), arm)
    GOARCH := arm
    GOPREFIX := 5
ifeq ($(DEB_HOST_ARCH), armel)
    GOARM := 5
else ifeq ($(DEB_HOST_ARCH), armhf)
    GOARM := 6
else
    $(error unrecognized arm architecture $(DEB_HOST_ARCH)!)
endif
else
    $(error unrecognized instruction set $(DEB_HOST_ARCH_CPU)!)
endif

It looks like some GOARM=6 code has creeped into GOARM=5 branch, but I could be mistaken.

Comment 1:

Thanks for reporting. I will tackle this issue soon.

Status changed to Duplicate.

Merged into issue #3331.
