optimize with -O3 for PIC targets (shared library). without heavy

use -Bsymbolic-functions, not -Bsymbolic. global variables are subject

9 years agoremove standalone syscall cruft
Rich Felker [Tue, 15 Feb 2011 19:39:02 +0000 (14:39 -0500)]
remove standalone syscall cruft

this was originally written for an early draft of the library where
non-standard functions would reside in a static library separate from
the shared libc.so, which would implement a pure standard. the idea
was not to depend on an implementation-dependent __syscall_ret
function in the main libc. but it turned out to be better to put
everything in a single library for both static and dynamic linking
uses, and thus the (incomplete) remnants of this feature were just
enlarging the source and binary.
