* libc: Access _logname_valid more efficiently.jilles2013-08-171-8/+1
| | | | | | | | | | | The variable _logname_valid is not exported via the version script; therefore, change C and i386/amd64 assembler code to remove indirection (which allowed interposition). This makes the code slightly smaller and faster. Also, remove #define PIC_GOT from i386/amd64 in !PIC mode. Without PIC, there is no place containing the address of each variable, so there is no possible definition for PIC_GOT.
* Add section .note.GNU-stack for assembly files used by 386 and amd64.kib2011-01-071-0/+2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch

* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-141-2/+2
| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.
* Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__)peter1996-05-051-5/+5
| | | | | | | | | | | In a nutshell, this macroizes the local/global symbol scoping rules that are different in a.out and ELF. It also makes the i386 assembler stubs conform to i386 PIC calling conventions - the a.out ld.so didn't object, but the ELF one needs it as it implements PIC jumps via PLT's as well as calls. The a.out rtld only worked because it was accidently snooping the grandparent calling function's return address off the stack.. This also affects the libc_r code a little, because of cpp macro nesting.
* First round of changes to clean up the RCSID mess in libc:dg1995-01-231-4/+5
| | | | | | | | 1) Changed LIB_SCCS and SYSLIB_SCCS to LIB_RCS and SYSLIB_RCS. 2) Changed sccsid[] variables to rcsid[] 3) Moved all RCSID strings into .text 4) Converted all SCCSID's to RCS $Id$'s 5) Added missing $Id$'s after copyright.
* First crack at making libc work with the new make macros. It compiles onwollman1994-08-051-0/+58
my machine, and a simple static (genassym) and shared (sysctl) executable both work. Still to be done: RPCand YP merge.
