Comment (by erikd):

 Have a simple Make script that passes on x86_64/linux and fails on
 arm64/linux:

 {{{
 #!/usr/bin/make -f

 GHC = inplace/bin/ghc-stage1
 GHCFLAGS = -fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output \
                 -no-user-package-db -rtsopts  -fno-warn-tabs \
                 -fno-warn-missed-specialisations -optc-Dlinux_HOST_OS=1
 -v0

 TESTDIR = testsuite/tests/rts

 all :
         rm -f *.o
         $(GHC) $(GHCFLAGS) -c $(TESTDIR)/T5435_asm.c -o T5435_load_v_asm.o
         $(GHC) $(GHCFLAGS) $(TESTDIR)/T5435.hs -o T5435_v_asm
         ./T5435_v_asm v ./T5435_load_v_asm.o

 }}}
