* cleanup shared library build system to be more $HOME-local-install friendlyRich Felker2011-06-271-13/+15
| | | | | the path for the dynamic linker is now configurable, and failure to install the symlink for it will not stop the build.
* use soname in ld-musl.so to prevent filename appearing in DT_NEEDEDsRich Felker2011-06-241-1/+1
|
* use symlink rather than bogus linker script for libc.soRich Felker2011-06-241-2/+2
| | | | the linker script caused a bogus DT_NEEDED entry
* adapt build/install/gcc-wrapper systems for dynamic linking supportRich Felker2011-06-231-5/+15

* various changes in preparation for dynamic linking supportRich Felker2011-02-241-3/+3
| | | | | | | | | | | | | | | | | 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.
