Sorry my previous answer was cut.
The motivation for prepass global code motion is indeed that after register
allocation, inter-block scheduling is even more restricted due to
anti-dependencies, including those due to live-out on side exit branches.
Global code motion is a key performance enabl

Hello,
Is there a way to activate control speculation of loads in GCC, starting with
the ia64 target? For a loop as simple as on GCC 7.5, I could not get any:
double
list_sum(list_cell list)
{
double result = 0.0;
while (list->next) {
list = list->next;
result += list->payload;
