--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jan Hubicka <hubi...@gcc.gnu.org>: https://gcc.gnu.org/g:f7dceb4e658399edfbf8dd0e08ce0c686bfa2c9d commit r10-7282-gf7dceb4e658399edfbf8dd0e08ce0c686bfa2c9d Author: Jan Hubicka <j...@suse.cz> Date: Fri Mar 20 00:42:13 2020 +0100 Fix cgraph_node::function_symbol availability compuattion [PR94202] this fixes ICE in inliner cache sanity check which is caused by very old bug in visibility calculation in cgraph_node::function_symbol and cgraph_node::function_or_virtual_thunk_symbol. In the testcase there is indirect call to a thunk. At begining we correctly see that its body as AVAIL_AVAILABLE but later we inline into the thunk and this turns it to AVAIL_INTERPOSABLE. This is because function_symbol incorrectly overwrites availability parameter by availability of the alias used in the call within thunk, which is a local alias. gcc/ChangeLog: 2020-03-19 Jan Hubicka <hubi...@ucw.cz> PR ipa/94202 * cgraph.c (cgraph_node::function_symbol): Fix availability computation.
