RE: Adding custom scheduler dependency between 2 insns

["Tomer Benyamini" <Tomer dot Benyamini at ceva-dsp dot com>]

Hi Maxim,

Thanks for the prompt response! I'm using gcc 4.2.0, and couldn't locate
sd_add_dep in sched-deps.c. Is add_dependence () an appropriate
equivalent?

Thanks,
Tomer

It sounds to me like you want a dirty hack.  Anyway, call to 
sched-deps.c: sd_add_dep () should be enough.
