* x86: Add sysdeps/x86/sysdep.hH.J. Lu2017-11-011-41/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new header file, sysdeps/x86/sysdep.h, for common assembly code macros between i386 and x86-64. Tested on i686 and x86-64. There are no differences in outputs of "readelf -a" and "objdump -dw" on all glibc shared objects before and after the patch. * sysdeps/i386/sysdep.h: Include <sysdeps/x86/sysdep.h> instead of <sysdeps/generic/sysdep.h>.

* X86_64: Don't use PLT nor GOT in static archives [BZ #20750]H.J. Lu2016-11-281-1/+2
| | | | | | | | | | | There is no need to use PLT nor GOT in static archives to branch to a function, regardless whether static archives is compiled with PIC or not. When static archives are used to create dynamic executable, PLT/GOT may be used. The resulting executable still works correctly. [BZ #20750] * sysdeps/x86_64/sysdep.h (JUMPTARGET): Check SHARED instead of PIC.
* Avoid an extra branch to PLT for -z nowH.J. Lu2016-05-241-2/+6
| | | | | | | | | | | | | | | | | | | When --enable-bind-now is used to configure glibc build, we can avoid an extra branch to the PLT entry by using indirect branch via the GOT slot instead, which is similar to the first instructuon in the PLT entry. Changes in the shared library sizes in text sections: Shared library Before (bytes) After (bytes) libm.so 1060813 1060797 libmvec.so 160881 160805 libpthread.so 94992 94984 librt.so 25064 25048 * config.h.in (BIND_NOW): New. * configure.ac (BIND_NOW): New. Defined for --enable-bind-now. * configure: Regenerated. * sysdeps/x86_64/sysdep.h (JUMPTARGET)[BIND_NOW]: Defined to indirect branch via the GOT slot.
