Lu <hjl.to...@gmail.com> Date: Tue Oct 13 05:10:24 2020 -0700 Gold: Enable safe ICF for shared object on x86-64 With commit 4aebb6312eb5dcd12f2f8420028547584b708907 Author: Rahul Chaudhry <rahulchaud...@google.com> Date: Wed Feb 15 00:37:10 2017 -0800 Improved support for --icf=safe when used with -pie. we now check opcode with R_X86_64_PC32 relocation, which tell branches from other instructions. We can enable safe ICF for shared object on x86-64. Also, global symbols with non-default visibility should be folded like local symbols. PR gold/21452 * x86_64.cc (Scan::local_reloc_may_be_function_pointer): Remove check for shared library. (Scan::global_reloc_may_be_function_pointer): Remove check for shared library and symbol visibility. * testsuite/icf_safe_so_test.cc (bar_static): New function. (main): Take function address of bar_static and use it. * testsuite/icf_safe_so_test.sh (arch_specific_safe_fold): Also check fold on x86-64. Check bar_static isn't folded. -- You are receiving this mail because: You are on the CC list for the bug.
