| 23-May-2014 |
uebayasi | Put missing END() markers to set ELF symbol size.
|
| 1.23 |
| 12-Sep-2013 |
joerg | branches: 1.23.2;
Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.
|
| 1.22 |
| 18-Nov-2011 |
joerg | branches: 1.22.6;
Mark __cerror as hidden and exploit that to simplify assembler.
|
| 1.21 |
| 09-Mar-2007 |
ad | branches: 1.21.36;
If I686_LIBC is defined, make syscalls using the 'sysenter' instruction.
|
| 1.20 |
| 07-Aug-2003 |
agc | Move UCB-licensed code from 4-clause to 3-clause licence.
Patches provided by Joel Baker in PR 22280, verified by myself.
|
| 1.19 |
| 20-Mar-2002 |
ross | use canonical indirect jmp & call syntax to squelch new as(1) warning
|
| 1.18 |
| 06-May-2001 |
ross | I have no idea why this syscall wrapper does some very un-unix-like
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.
*
* However, I do know that it should use jb and not jl.

| 1.17 |
| 08-Dec-2000 |
mycroft | branches: 1.17.2;
Use the SYSTRAP() macro more uniformly.
|
| 1.16 |
| 26-Jun-2000 |
kleink | Thinko in previous: we do always use an internal name.
|
| 1.15 |
| 23-Jun-2000 |
kleink | Add internal names for brk() and sbrk().
|
| 1.14 |
| 03-Apr-2000 |
mycroft | branches: 1.14.4;
Clean up.
* _REENTRANT is always defined.
* The vfork() stubs can use cerror.
|
| 1.13 |
| 03-Apr-2000 |
mycroft | Repair syscall stubs that were not updated when the cerror interface was
modified.
|
| 1.12 |
| 08-Feb-1999 |
christos | branches: 1.12.2;
Amend for the PLT fixes, things broke last night with the changes to SYS.h
and cerror.S. In particular, the syscalls in the files committed below were
broken.
|
| 1.11 |
| 14-Jan-1999 |
kleink | * On architectures using ELF, and conditionally on those in transition, rename
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.
|
| 1.10 |
| 16-Jul-1997 |
christos | RCSID fixes: Always use the NetBSD rcsid and the macro RCSID() defined in
<machine/asm.h>; Also syscalls should be protected using the SYSLIBC_SCCS
define not LIBC_SCCS
|
| 1.9 |
| 26-Oct-1994 |
mycroft | Use trap gate to enter kernel.
|

| 27-Jan-1994 |
mycroft | Random cleanup.
|
| 1.6 |
| 27-Jan-1994 |
mycroft | SYS_brk --> SYS_break. Where's my axe?
|
| 1.5 |
| 27-Jan-1994 |
mycroft | More stylistic changes.
|
| 1.4 |
| 24-Jan-1994 |
jtc | Optimization tweaks:
Use testl %reg,%reg instead of cmpl $0,%reg
Use xorl %reg,%reg instead of movl $0,%reg
|
| 1.3 |
| 06-Dec-1993 |
pk | Use PIC_PLT for error returns.
Correct operand order in accessing `minbrk' and `curbrk'.
|
| 1.2 |
| 21-Oct-1993 |
jtc | Move the old berkeley sccs id into the header comment like it is done
for other source files.
