* ELF preparation step 2:Søren Schmidt1998-05-261-2/+2
| | | | | | | | | | | | | | | | | Move a.out libraries to /usr/lib/aout to make space for ELF libs. Make rtld usr /usr/lib/aout as default library path. Make ldconfig reject /usr/lib as an a.out library path. Fix various Makefiles for LIBDIR!=/usr/lib breakage. This will after a make world & reboot give a system that no longer uses /usr/lib/*, infact one could remove all the old libraries there, they are not used anymore. We are getting close to an ELF make world, but I'll let this all settle for a week or two... Notes: svn path=/head/; revision=36397

* Don't share sources with i386-elf. That was too difficult. 8-(John Birrell1998-03-111-4/+7
| | | | | | | | | | | Add a bootstrap mode so that non-rtld versions of these objects can be built when bootstrapping the system with NetBSD tools, headers and libraries. Once the FreeBSD tools are built, the FreeBSD headers are installed and *then* these objects can be recompiled with the rtld references. Phew. Notes: svn path=/head/; revision=34487
* Sharing the crt sources with i386-elf wasn't too successful. The crtiJohn Birrell1998-03-113-20/+167
| | | | | | | | | | | | | | | | | | | | | asm code didn't link the way it was supposed to and the calling convention for the entry "function" turned out to be very different. On alpha it's a true function, but on i386 it's a fudge. Blech. So jdp suggested keeping separate sets of source and avoiding lots of #ifdefs. These files are based on his i386-elf code, with crt1.c borrowing code from NetBSD's crt0. The copyright reflects that. Complicating matters, the code turned out to be difficult to bootstrap build using NetBSD tools. To compile against the FreeBSD rtld header requires FreeBSD specific headers, but these can't be installed until the tools are built, and they can't be built without the FreeBSD crt objects. Anal retentive. So I introduced a HAVE_RTLD #define that isn't set during the build process until all the tools are built and the headers installed.

* Trash startup sources from NetBSD in favour of jdp's FreeBSD sourceJohn Birrell1998-03-104-419/+23
| | | | | | | | | | | | now that has been committed. The makefile is derived from the i386-elf version, modified to pick up most of the source (except crt1.c) from i386-elf. With minor changes to i386-elf/crt1.c, this directory can be combined with i386-elf to be a single csu/elf directory for all seasons. Notes: svn path=/head/; revision=34454

* Remove the include of <dlfcn.h> from crt0.c; it is not needed nowJohn Polstra1998-02-113-79/+3
| | | | | | | | | | that the dl* trampolines have been moved into libc. Move dlfcn.h from src/lib/csu/i386 into src/include. Nothing in src/lib/csu/i386 uses it any more. Notes: svn path=/head/; revision=33236
* Move the trampolines for dlopen and related functions from crt0.oJohn Polstra1998-02-094-481/+18
| | | | | | | | | | | | | | | | | | into libc. This reduces the size of every dynamically linked executable by 248 bytes, and it reduces the size of static executables by a lesser amount. It also eliminates some global namespace pollution. With this change in place, the source for dlfcn.h should probably be moved to "/usr/src/include". I'll save that for another day. Compatibility note: Programs which use dlopen, if compiled on systems with this change, will not run on systems with a libc from prior to this change. Very few programs use dlopen, so I think that is OK. Notes: svn path=/head/; revision=33180

* Declare the constructor/destructor linker sets as extern rather thanJohn Polstra1997-04-091-3/+24
| | | | | | | | | | | | | | | | | | | | common. Add one do-nothing element to each set. This ensures that the linker realizes that they are linker sets rather than simple commons, and makes it possible to link c++rt0.o into every shared library regardless of whether it is a C++ library or not. Without this change, the constructors and destructors in the main program could be executed multiple times. This change is going to make it possible to get rid of the CPLUSPLUSLIB makefile variable once and for all. It is a piece of the solution to PR gnu/3505 (gcc -shared). Finally, it fixes a heretofore unreported bug: If CPLUSPLUSLIB was set in a makefile for a C++ shared library that had no static constructors or destructors in it, then the main program's constructors and destructors would be executed multiple times.

* Set the "crt_ldso" member of the crt-to-ld.so interface structure. ThisJohn Polstra1997-01-111-1/+2
| | | | | | | | | | | | | was apparently overlooked at the time the member was added. Its absence causes some error messages from the dynamic linker to begin with "(null):" instead of with the pathname of the dynamic linker as they should. I am also adding a work-around to the dynamic linker, to cope with legacy binaries that were built with older versions of crt0. Notes: svn path=/head/; revision=21571
* Use ${COPY} instead of -C for installing non-source files. crt*.oBruce Evans1997-01-011-2/+2

* When linking with no rtld support, provide stub dl*() functions thatPeter Wemm1996-12-281-1/+43

John Polstra once mentioned that this was on his "todo" list. Note that one can use: cc -Wl,-Bstatic -o foo foo.o and get an executable that has it's libraries statically linked, but has a fully functional runtime linker so the executable can call dlopen() and have it work.

The crt startup tries version 4 first, and falls back to version 3, so an executable that is linked on -current will work with the ld.so on 2.1.x and less.

* Changed the dimensions of __CTOR_LIST__ and __DTOR_LIST__ from 0John Polstra1996-02-201-14/+6
| | | | | | | | | | | | | | | | | to 2. This makes them agree with the declarations in libgcc, and clears the way once again for linking c++rt0.o into all libraries, and eliminating CPLUSPLUSLIB from <bsd.lib.mk>. (I have not made that change yet, because there is still a bootstrapping problem for "make world".) Also, removed a check which ensured that the constructor count in the first word of __CTOR_LIST__ was greater than zero before traversing the list. I had added that check earlier, but it is no longer necessary, now that there is guaranteed to be at least 2 words in __CTOR_LIST__. Notes: svn path=/head/; revision=14161

| | | | | | | | | | | | | | | | | | | | the loop that invokes the static constructors. That makes it safe to link c++rt0.o into any shared library, even one that does not have any static constructors. Formerly, doing that would cause a bus error. If the library has no static constructors, __CTOR_LIST__ comes out as a simple 4-byte COMMON region, and it does not have the usual NULL word that terminates the list of constructors. This caused the old code to "call" a garbage address via the non-existent entry __CTOR_LIST__[1]. The analogous code that invokes the static destructors was already safe. This change is fully backward-compatible. Reviewed by: dfr@render.com (Doug Rabson) Notes: svn path=/head/; revision=13441
