Description at@altlinux.org 2003-01-13 20:04:33 MSK 
According to Ulrich Drepper paper, it is worth to pass -O1 command line option to GNU linker to perform final binary optimizations. Currently this relates at least symbol table optimization for shared libraries. The author also states that new linker version will be developed which will use advanced optimizations techniques.

%optflags_linker -Wl,-O1
%optflags_default ... %optflags_linker

Comment 3 Dmitry V. Levin 2005-09-05 00:35:22 MSD 
Do you suggest to set default LDFLAGS?
Comment 4 Dmitry V. Levin 2006-01-10 02:07:18 MSK 
Or maybe just enable it in ld by default?
Comment 5 Denis Smirnov 2006-01-10 13:50:24 MSK 
Если это работает корректно -- лучше установить по-умолчанию в ld.
Comment 6 Dmitry V. Levin 2006-06-07 03:12:34 MSD 
Enabled by default in binutils-2.16.91.0.5-alt2 on Mon Jan 09 2006,
