Hi.
Again, the param is set based on optimize_size:
if (opts->x_optimize_size)
/* We want to crossjump as much as possible. */
SET_OPTION_IF_UNSET (opts, opts_set, param_min_crossjump_insns, 1);
So that, the param should be per-function. The only usage is in cfgcleanup
that is done per-function.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
