From 67c0579669ba1fc265d770252fab31babf887329 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 8 Jun 2018 10:28:38 -0700 Subject: Mark _init and _fini as hidden [BZ #23145] _init and _fini are special functions provided by glibc for linker to define DT_INIT and DT_FINI in executable and shared library. They should never be put in dynamic symbol table. This patch marks them as hidden to remove them from dynamic symbol table. Tested with build-many-glibcs.py. [BZ #23145] * elf/Makefile (tests-special): Add $(objpfx)check-initfini.out. ($(all-built-dso:=.dynsym): New target. (common-generated): Add $(all-built-dso:$(common-objpfx)%=%.dynsym). ($(objpfx)check-initfini.out): New target. (generated): Add check-initfini.out. * scripts/check-initfini.awk: New file. * sysdeps/aarch64/crti.S (_init): Mark as hidden.
