Lu <hjl.to...@gmail.com> Date: Wed Apr 8 09:47:35 2020 -0700 x86: Insert ENDBR if function will be called indirectly Since constant_call_address_operand has ;; Test for a pc-relative call operand (define_predicate "constant_call_address_operand" (match_code "symbol_ref") { if (ix86_cmodel == CM_LARGE || ix86_cmodel == CM_LARGE_PIC || flag_force_indirect_call) return false; if (TARGET_DLLIMPORT_DECL_ATTRIBUTES && SYMBOL_REF_DLLIMPORT_P (op)) return false; return true; }) even if cgraph_node::get (cfun->decl)->only_called_directly_p () returns false, the fuction may still be called indirectly. Copy the logic from constant_call_address_operand to rest_of_insert_endbranch to insert ENDBR at function entry if function will be called indirectly. gcc/ PR target/94417 * config/i386/i386-features.c (rest_of_insert_endbranch): Insert ENDBR at function entry if function will be called indirectly. gcc/testsuite/ PR target/94417 * gcc.target/i386/pr94417-1.c: New test. * gcc.target/i386/pr94417-2.c: Likewise. * gcc.target/i386/pr94417-3.c: Likewise.
