[PATCH] D41644: Rename --icf-data and add a corresponding flag for functions

[Rafael Avila de Espindola via Phabricator via llvm-commits]

espindola created this revision.
espindola added reviewers: ruiu, emaste, rnk, dim.

This is a replacement to https://reviews.llvm.org/D41207. I could not figure out how to update it with my new phab account.

When we have --icf=safe we should be able to define --icf=all as a shorthand for --icf=safe --ignore-function-address-equality.

For now --ignore-function-address-equality is used only to control access to non preemptable symbols in shared libraries.
