Mark internal functions with attribute_hidden to allow direct access to internal functions within libc.so and libc.a without using GOT nor PLT. Size comparison of libc.so: On x86-64: text data bss dec hex Before: 1728577 20584 17088 1766249 1af369 After : 1728593 20584 17088 1766265 1af379 The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined since it is hidden, which increases the code size of gconv_dl.os by 18 bytes. On i686: text data bss dec hex Before: 1869039 11444 11112 1891595 1cdd0b After : 1868635 11444 11112 1891191 1cdb77 The code size is decreased by avoiding GOT/PLT for hidden functions.
