Hi.
The param is changed here:
/* Restrict the amount of work combine does at -Og while retaining
most of its useful transforms. */
if (opts->x_optimize_debug)
SET_OPTION_IF_UNSET (opts, opts_set, param_max_combine_insns, 2);
and so that it should be per-function. The only usage is in combine RTL
pass, which is per-function optimization.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
