I've tried compiling the problematic test case with the sh-lra branch (LRA
enabled) and '-Os -m4 -ml -matomic-model=soft-gusa' and '-Os -m4 -mb
-matomic-model=soft-gusa'. The problem seems to be gone for those parameters,
but when compiling for '-O2 -m4 -ml -matomic-model=soft-gusa' it crashes:
internal compiler error: in check_rtl, at lra.c:1928
TEST_FUNCS (complex_float_add, _Complex float, , += 1, 0, 20000)
