eeh 41065b740e Don't need `start' in crt0.o any more. ld expects `_start' as the entry
symbol, while gcc likes `__start'.

matt 0ce5ca145f Change to use a register prefix. 2002-02-24 01:06:18 +00:00
matthias 21fb786623 Declare the global register variable kps_strings before including anything
as this needs to be done before any function is defined (and there seems
to be a function definition in one of the include files).

drochner e757f639d2 don't include <machine/asm.h> to avoid conflicts with definitions

thorpej fd9112a780 Build and install crtfm.o (sets the Alpha FP_C in a way that GCC's
-ffast-math on Alpha expects).
2002-01-14 01:31:58 +00:00
thorpej 24ca47c4d5 * Use the new ALPHA_SET_FP_C sysarch call.
* Provide an internal sysarch entry point, so that this works
  with statically-linked programs.
2002-01-14 01:31:00 +00:00
thorpej 655925395a Support for the GCC "-ffast-math" option on the Alpha. 2002-01-13 20:05:42 +00:00
thorpej caaec27cfe * Use += to assign OBJS so that machine-dependent Makefiles can
add their own objects to the list.
* Garbage-collect an unneeded CLEANFILES assignment.

thorpej d8abc59932 Add support for invoking GNU C++ local destructors in shared objects
via the __cxa_finalize() mechanism.

XXX Only enabled for new-toolchain platforms, as it requires the assembler
to support the .hidden pseudo-op.
2001-12-31 00:40:11 +00:00
thorpej a50163af65 Build separate crt{begin,end}.o and crt{begin,end}S.o files, rather
than linking them at install time.  Forthcoming changes require different
behavior for static vs. shared object versions of these files.

thorpej c41160abff Add support for registering Java classes emitted by the Java compiler
(e.g. the Java compiler in GCC 3.x) into the ".jcr" section.

skrll 6d6c931c5a This is an a.out thing and doesn't belong here. 2001-10-26 16:05:25 +00:00
scw f768a5c42b Reduce the alignment constraint from 4 to 2. This fixes the problem where
gas(2) pads the text segment with 0x0 instead of NOP. Since m68k instructions
only need 16-bit alignment, .align 2 works just fine.

bjh21 751e6fa590 Ensure that the stack is aligned to an 8-byte boundary before calling C code.

simonb 9a68629ca6 Enlarge the stack frame to 16 bytes, and store the return address 8
bytes in instead of at the start, to leave room for a .cpload to store
the gp at offset 0 in the frame.  Allow 8 bytes for each (for mips64
one day...).

.cpload overwrite problems noted by Michael Hitch.

matt ee6a16ad18 Add a secondary label called __start (makes gcc 2.95.3 happier) and rename
the internal __start to ___start.   (Since -e is not supplied by default,
this has no effect on a native build.)
2001-08-05 00:01:27 +00:00
thorpej 102df4197d Enable DWARF2 EH support. Confirmed working w/ GCC 2.95.3 on sparc
and i386.
2001-08-03 14:26:13 +00:00
thorpej a6855eea24 Add support for DWARF2 frame unwinding/exception handling. This
should be sufficient for GCC 2.95.3, and probably GCC 3.0 as well.

Not yet enabled by default; further testing required.

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.
