fvdl a84b13f43f CSU for x86-64 port. 2001-06-19 00:49:06 +00:00

fredette e80c95ddb2 Don't use an EA with a scaled index, it isn't supported on the 68000. 2001-05-17 21:21:07 +00:00
fredette 872a39428c Don't compile with -fPIC when MACHINE_ARCH is m68000. 2001-05-17 21:17:02 +00:00
kleink 7bd28edec7 Add, but do not yet enable, m68k code for .init and .fini section fallthroughs. 2001-05-12 00:17:55 +00:00
ross 2d62241cb9 Reorganization of crtbegin/crtend. 
o  Primary mod: alpha and i386 code for .init and .fini section fallthroughs
o  Actual fallthru is not yet enabled, see csu/{alpha,i386_elf}/Makefile
o  When enabled, should fix bin/12865 & should fix at least one WINE bug,
   see http://www.winehq.com/hypermail/wine-devel/2001/05/0021.html
o  Also, removed the function pointer hack put in to prevent gcc from
   incorrectly attempting to do short calls over section boundaries,
   on some architectures, rather, simply simply move ctors() and dtors()
   into .init and .fini.
Other notes.
o  Our crtbegin.c and crtend.c were completely in C, despite
   the fact that .init and .fini section fallthroughs require machine code.
   These modules implement the gnu ctors/dtors mechanism directly, eliminating
   in part the need for the elf .init/.fini section fallthrough. However,
   if we ever want to use the gnu-provided constructor support, we need to
   do the fallthrough, at least one program (WINE) apparently uses the
   feature independently, and other compilers may depend on the mechanism.
o  It is amusing that the previous NetBSD _init() and _fini() were put
   into the .init and .fini sections, because nothing is gained over
   plain .text if they don't fall through. Cargo cult!
o  Other elf ports will need to copy the alpha and i386 example mods.

bjh21 0113cca535 Our ARM ELF ld(1) currently has problems with PIC relocations, so don't 
generate them.  I suspect this is safe until we get PIC in general working.

mycroft 94581370f5 The ELF ABI declares that argc must fill an `argument slot'. Make it so. 
For __sparc_v9__ only, do a hack to make executables work temporarily before
and after the kernel is switched.

mycroft 209e309de1 Always dereference argc as an int. 2000-07-26 02:11:44 +00:00
mycroft 0ef3f52396 Make this work before and after the kernel is switched to DTRT with argc. 
This is temporary, only to make the flag day less painful.

matt d71ca2d66e __syscall takes a quad_t as its first argument, not an int. 
_strrchr takes an int (due to promotion) as its third arg.
don't print the null byte at the end of string.
error messages should end with a linefeed.

christos 3d65200a80 remove initialization of mainprog_obj from here; it is too late for .ini 
sections that want to use dlopen(3).

bjh21 6c97e2bd78 Initial commit of arm26 port 2000-05-09 21:55:44 +00:00
dmcmahill 7348e432f3 change -fpic to -fPIC. Among other things this will let sparc shared 
c++ libraries built with pkglibtool (which uses -fPIC) work.
change approved by mycroft.

eeh 818cfe2268 Workaround for gcc 2.96 bugs. 1999-12-30 15:34:47 +00:00
lukem fe5a2bf74b remove the ``static'' from `static void __start()' and `static void ___start()' 
because an overly aggressive gcc -O3 "cleverly" optimizes the functions out.
noted in [port-i386/8493], but seen in other ports as well.

matt 741f18b695 Initial VAX ELF32 support (mostly untested). It's checked primarily for 
testing and archival for now.  I don't expect anyone to work with it
since the binutils and gas changes are still pending.  But you got to
crawl before you walk.

and provide weak aliases.

by ld for the i386 ELF case.

kleink 28d76befd4 When calling dlerror() in a non-dynamically linked executable, return a pointer 
to an error string rather than NULL (`no errors occured) to indicate the cause
of failure return values of other dl*() interfaces.

simonb 45c86b888b Instead of rolling our own "install" target, use FILES/FILESDIR and 
LINKS to that things like "make install UPDATE=" work properly.
