riastradh | ld.elf_so(1): Nix trailing whitespace.
No functional change intended.
|
| 1.24 |
| 17-Aug-2014 |
matt | Add proper registers for register counts.
|
| 1.23 |
| 17-Aug-2014 |
matt | add a missing register prefix.
|
| 1.22 |
| 22-Mar-2014 |
matt | branches: 1.22.4;
Make sure r1 is preserved _rtld_bind_start.
|
| 1.21 |
| 21-Mar-2014 |
matt | Simplify. If we got called via a calls $n, *pcrel32, instead of constructing
a new stack frame, back up the PC by 7 and return back to the calls so it
will be reinvoked. (This is by far the most common way it gets invoked).
Otherwise rebuild a new callframe and jump to the routine.
|
| 1.20 |
| 19-Mar-2014 |
joerg | Save actual start of function, not address of entry mask on the stack.
|
| 1.19 |
| 19-Mar-2014 |
matt | Fix two bugs. (jump past entry mask, fix insv)
|
| 1.18 |
| 19-Mar-2014 |
matt | Once we know the bound routine, rebuilt a new callframe that can be unwound
properly.
|
| 1.17 |
| 18-Mar-2014 |
matt | Add .cfi ops so that one can unwind through this.
|
| 1.16 |
| 02-Mar-2003 |
mycroft | branches: 1.16.54; 1.16.60;
Shorten rtld_start() slightly -- there's a base-relative _DYNAMIC pointer at
the beginning of the GOT, so we don't need an extra one here. Also, remove a
bogus comment -- we do in fact have to do fixups, because there are pointers in
ld.elf_so's data segment that need to be relocated.
|
| 1.15 |
| 05-Oct-2002 |
mycroft | Minor cleanup.
|
| 1.14 |
| 27-Sep-2002 |
mycroft | We don't need to save r7, either...
|
| 1.13 |
| 27-Sep-2002 |
mycroft | Put back the short-circuiting code -- Matt claims there are functions that rely
on it.
OTOH, don't bother saving r6 a second time.
|
| 1.12 |
| 27-Sep-2002 |
mycroft | 1) There is no reason to flush the I$ here, given that we do not modify any
instructions. Function calls use GOT indirection, and we only patch the
GOT.
2) The mask-comparison optimization always fails, because the saved mask
always has 0x2000 set, and the PLT stub mask never does. So, remove it.
|
| 1.11 |
| 27-Sep-2002 |
mycroft | Save one more instruction.
|
| 1.10 |
| 26-Sep-2002 |
mycroft | Save relocbase in %r10, not %r1.
Also, save one instruction.
|
| 1.9 |
| 26-Sep-2002 |
mycroft | Implement a self-relocate function for the VAX.
|
| 1.8 |
| 12-Sep-2002 |
mycroft | Figure out the relocation offset and pass it to _rtld().
|
| 1.7 |
| 24-Feb-2002 |
matt | branches: 1.7.2;
Change to use a register prefix.
|
| 1.6 |
| 07-Aug-2000 |
matt | Simplify some stuff.
|
| 1.5 |
| 17-Jul-2000 |
matt | More VAX ELF changes.
|
| 1.4 |
| 14-Jul-2000 |
matt | No need for RELOCATE_SELF since the VAX does real PIC. Rewrite the bind
routine to deal with JMP .vs. CALLx differences.
|
| 1.3 |
| 03-Jul-2000 |
matt | Update to current <machine/asm.h>
|
| 1.2 |
| 22-May-2000 |
matt | minor fix now that i've defined the plt0 entry.
|
| 1.1 |
| 21-Aug-1999 |
matt | 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.
|
| 1.7.2.1 |
| 28-May-2004 |
tron | Apply patch (request by skrll in ticket #1702):
Bring "ld.elf_so" (mostly) in sync with NetBSD-current:
- MI and MD (e.g. under NetBSD-alpha) performance improvements
- RTLD_SELF, RTLD_NEXT, RTLD_DEFAULT support
- much better structured code
- closes PR bin/25464
|
| 1.16.60.1 |
| 20-Aug-2014 |
tls | Rebase to HEAD as of a few days ago.
|
| 1.16.54.1 |
| 22-May-2014 |
yamt | sync with head.
for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.
this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")

| 1.22.4.1 |
| 20-Aug-2014 |
martin | Pullup the following to netbsd-7 (requested by matt in ticket #37):
external/gpl3/gcc/dist/gcc/config/vax/builtins.md 1.4
external/gpl3/gcc/dist/gcc/config/vax/vax.c 1.10
Rework so that the ctzsi builtin is supported.
lib/libc/compiler_rt/Makefile.inc 1.26
VAX does need __clzsi2
libexec/ld.elf_so/arch/vax/rtld_start.S 1.23
libexec/ld.elf_so/arch/vax/rtld_start.S 1.24
add a missing register prefix.
Add proper registers for register counts.
