Adding custom scheduler dependency between 2 insns

[Tomer Benyamini]

Hi,

I was wondering if it is possible to create a dependency between 2 insns
through a specific scheduler hook (maybe through
TARGET_SCHED_DEPENDENCIES_EVALUATION_HOOK) even though the insns are not
really dependent (not really read-after-write etc.). If it is possible,
what is the best way to do it?

Thanks,
Tomer
