Rich Felker	ec05a0b08f	adapt build/install/gcc-wrapper systems for dynamic linking support	2011-06-23 22:13:47 -04:00
Rich Felker	41d518360f	various changes in preparation for dynamic linking support ... prefer using visibility=hidden for __libc internal data, rather than an accessor function, if the compiler has visibility. optimize with -O3 for PIC targets (shared library). without heavy inlining, reloading the GOT register in small functions kills performance. 20-30% size increase for a single libc.so is not a big deal, compared to comparaible size increase in every static binaries. use -Bsymbolic-functions, not -Bsymbolic. global variables are subject to COPY relocations, and thus binding their addresses in the library at link time will cause library functions to read the wrong (original) copies instead of the copies made in the main program's bss section. add entry point, _start, for dynamic linker.	2011-02-24 16:37:21 -05:00
