Interesting. I think it's the first time we run into this problem. I
don't see force_gimple_operand trying to emit low GIMPLE. But we always
use it from the optimizers, so it should.
You cannot force the omp_atomic gimplifiers to emit low GIMPLE as those
are called by the GENERIC->GIMPLE conversion. The easiest way to fix
this, I think, is to call lower_stmt() from force_gimple_operand() after
the call to gimplify_expr. For this you'll need to setup a stmt
iterator on the resulting list of statements from gimplify_expr and call
lower_stmt on each of them (this should be implemented in gimple-low.c).
Longer term, I think we need to have an indicator of what level of
GIMPLE the function is in. This way the various helpers like
force_gimple_operand can decide what to do.
