> Hi, > > in PR 61340 it has been reported that clang warns about unhandeld enum > values in a switch (gcc does not, I guess I'll open a new PR for > that). > > Fixed thusly by adding a default label with a gcc_unreachable() in > both. The potentially unhandled enum value in both cases is > IPA_REF_ALIAS which we cannot encounter because > > 1) in ipa-pure-const.c we are not processing aliases and > > 2) in ipa-reference.c we analyze references of a function to a > variable and that cannot be an alias. > > OK for trunk?
